how to pick up MPXM2053GS by nozzle During the SMT process, air may get blown into the pressure port from the pick-and-place nozzle. Is it possible to damage the sensor inside? Re: how to pick up MPXM2053GS by nozzle Hello David, A brief, low-pressure air pulse from the pick-and-place nozzle into the side pressure port is unlikely to cause damage, provided the applied pressure does not exceed the device's maximum rated overpressure. However, repeated or high-pressure air blasts could in principle stress the diaphragm or, under extreme conditions, compromise it. To avoid any risk entirely, the recommended approach is to position the pick-and-place nozzle on the flat top body surface of the M-PAK package, away from the side pressure port. This ensures the nozzle never contacts or directs airflow into the sensing port opening. Application Note AN1984 – Handling Freescale Pressure Sensors provides specific guidance on nozzle design and placement for this device family and is the primary reference for SMT handling of MPX-series sensors. Application Note AN936 – Mounting Techniques, Lead Forming, and Testing of the MPX Series Pressure Sensors is also a useful complement. Please note that as of February 2, 2026, NXP MEMS sensor products (including the MPXM2053GS) have been transitioned to STMicroelectronics. For ongoing product support and handling documentation going forward, I recommend also consulting STM directly. BRs, Tomas

LAN96455F i.MX95とのイーサネット・スイッチ統合 – デバイスツリーガイダンス こんにちは、NXPチームの皆様、 Microchip LAN96455F Ethernet Switch(LAN9645xファミリ)をカスタムのi.MX95 19x19 LPDDR5ボード(imx95-19x19-evk.dtsベース)に統合しています。適切なデバイスツリー統合に関するガイダンスをいただければ幸いです。 Re: LAN96455F Ethernet Switch Integration with i.MX95 – Device Tree Guidance Linuxの場合、外部スイッチポートを個別に公開・管理する予定がある場合は、LAN96455FをDSA イーサネット・スイッチとしてモデル化してください。スイッチのCPU/アップリンクポートに接続するi.MX95 ENETC/NECイーサネットMACはDSAコンジットインターフェースであるべきです。LAN96455FポートはDSAユーザーNetDevとなります。DSAは、専用CPUポートがSoCイーサネットコントローラに接続されたスイッチ向けに設計されており、CPUポート自体の別のネット開発ではなく、フロントパネルごとの「ユーザー」インターフェースを作成します。 適切なデバイスツリーの構造は次のとおりです。 /* &enetX / &mdioX を実際の i.MX95 BSP ラベルに置き換えてください  * 選択した NETC ENETC ポートについては、imx95-19x19-evk.dts / imx95.dtsi を参照してください。 */ /* i.MX95 ENETCポートがCPU/アップリンクポートに接続LAN96455F */ &enetX {                  ステータス = "okay";               /* i.MX95とLAN96455F間の電気インターフェースを一致させる必要があります: * "rgmii-id", "rgmii", "sgmii", "2500base-x", など。                */               phy-mode = "rgmii-id";               /* MACからスイッチへのCPUポートは通常PHYがないため、説明してください               * LAN96455F CPU ポートが実際に固定リンクでない限り、固定リンクとして扱われます。                  * PHY/PCS を介して管理されます。                */ 固定リンク {                              速度 = <1000>; 全二重; }; }; /* MDIOコントローラはスイッチ マネジメント インターフェースにアクセスするために使用されました。 * i.MX95 NETCは外部PHY用のマスターMDIOインターフェースを備えています。  * 条項 22 および条項 45 を支持する 。 */ &mdioX {                  ステータス = "okay"; イーサネットswitch@0 {                              /* LAN9645xのドライバー/バインディングの互換文字列を使用してください * カーネル/BSP に同梱されています。この文字列を創作しないでください。 */ 互換性 = "microchip, reg = <0>; /* MDIO アドレスをボード上に固定 */ ポート { #address-cells = <1> #size-cells = <0>;                                            port@0 { reg = <0>; label = "lan0"; /* この外部ポートに外部 PHY がある場合: * phy-handle = <&phy0> * phy-mode = "..." */                                             };                                            port@1 { reg = <1>; label = 「lan1」;                                             };                                            port@2 { reg = <2>; label = "lan2";                                             };                                            port@3 { reg = <3> label = "lan3";                                             }; /* LAN96455F CPU/アップリンクポート番号は、 * マイクロチップのデータシート/ドライバ定義。 */                                            ポート@N { reg = ; label = "CPU"; イーサネット = <&enetX>;                                                            phy-mode = "rgmii-id";                                                            固定リンク {                                                                             スピード = <1000>; 全二重;                                                               };                                             };                           }; }; }; DTSを最終決定する前に確認すべき重要なポイント： カーネルから実際のLAN9645xバインディングを使用してください。取得したソースから公開されたメインLAN96455Fライン固有のバインディングを確認できなかったため、上記の互換性文字列は意図的にプレースホルダーとして使っています。NXPのBSP/Microchipドライバーツリーのドキュメント/devicetree/bindings/net/dsa/またはMicrochip LAN9645xドライバーソースを確認してください。 イーサネット = <&enetX>すべてのスイッチポートではなく、SwitchのCPUポートに設置しています。 DSAポートバインディングでは、イーサネットプロパティがスイッチポートがコネクテッドされているホストイーサネットデバイスへのphandleであると書かれています。 CPU/DSAポートには、phylink形式のリンク記述が必要です。CPUポートの場合、イーサネット=<&enetX>;このバインディングはphyモードと固定リンク、phyハンドル、またはマネージドのいずれかを必要とします。 固定リンクはMACからスイッチへのCPUポート直接続に使います。 一般的なイーサネットバインディングは、速度、全二重、オプションの一時停止特性を持つ固定リンクを定義しています。サポートされる固定リンク速度には、オブジェクト形式で10/100/1000/2500/5000/10000 Mbit/sが含まれます。 RGMIIの遅延モードは正確に設定してください。phy-mode = "rgmii-id" は、PCB が RGMII クロック/データ遅延を提供せず、MAC/PHY 側が内部遅延を提供する必要があることを意味します。plain "rgmii" は、PCB の配線が遅延を提供することを意味します。ほとんどのカスタムボードでは、レイアウトで意図的に遅延を追加しない限り、「rgmii-id」が想定される開始点となります。 また、i.MX95のMACがスイッチCPUポートに接続されている場合、通常の外部PHYのように設定しないでください。DSAモデルでは、MACが導管となり、外部ユーザーのポートはスイッチポートノードで表されます。 lan0やlan1などのLinuxインターフェースが期待できます。DSAはフロントパネルポート用のユーザーネットワークデバイスを作成し、DSAラベルプロパティがnetdevの名前となります。 準備チェック: dmesg | grep -i -E "dsa|lan964|mdio|enetc|netc" IPリンク cat /sys/class/net/ /dsa/tagging 2>/dev/null ip link set up ip link set lan0 up ethtool lan0 lanXインターフェースが表示されない場合は、次の順番でデバッグを行います:MDIOアドレス/ストラップ値、GPIOタイミングのリセット、ドライバーの要求による割り込みGPIO、正しいLAN9645x互換、正しいCPUポートレジグ、i.MX95とスイッチ間の正しい物理モード/固定リンク速度。 i.MX95 ENETCポートをDSA導管として使い、MDIO/SPI管理バスの下でポートブロックでLAN96455Fを記述し、スイッチCPUポートをENETC MACに戻すようにします。イーサネット = <&enetX>に加え有効なphyモードと固定リンク/マネージド/phyハンドルを使用します。

NXP S32K312 CAN0 – FIRC 与 FXOSC 时钟源导致 CAN 错误 大家好， 我正在使用 S32K312 上的 CAN0，速率为 500 kbps，采样点为 87.5%。 最初，我将 CAN0 设置为使用内部 FIRC_CLK 作为时钟源。当我将 S32K312 连接到具有多个 CAN 节点的网络时，我注意到出现了很多 CAN 错误帧。 然后，我将 CAN 时钟源从 FIRC_CLK 切换到外部 FXOSC_CLK，同时保持 CAN 比特率和采样点不变。做出这一改变后，通信变得稳定，我不再看到错误帧。 请问有人能帮我理解一下为什么将时钟源从 FIRC_CLK 切换到 FXOSC_CLK 就能解决 CAN 错误吗？ Re: NXP S32K312 CAN0 – FIRC vs. FXOSC Clock Source Causing CAN Errors 你好@Karthik_R ， 通常不建议将 FIRC 时钟用于 FlexCAN 通信，因为根据 CAN 协议 (ISO 11898-1)，其精度超过了 ~1% 的要求。从 S32K3 的数据表中可以看出，FIRC 的偏差为 +/- 5%。 建议使用 FXOSC 或由 XOSC 运行的 PLL。您可以参考FlexCAN 位时序计算文档和MPC5xxx/S32Kxx/LPCxxxx：CAN / CAN FD 位时序计算工具进行时钟和时序计算。 希望这能说清楚。 此致， 朱利安

GCCはプラグマステートメントを無視して、コードをITCMメモリに配置します。 こんにちは！ ここでは、S32K3バージョン1.7.1用のMatlab R2025b、Simulink、およびMBDTを使用しています。 私たちが開発中のモーターコントローラアプリケーションの性能を最適化するために、コードの一部をITCMメモリに、さらに後にはデータ用のDTCMメモリに配置したいと考えています。 今のところ、ワークフローをテストするために、ITCMのメモリに関数を配置しようとしています。Simulink/Embedded Coderを使って、以下のような正しいプラグマステートメントをCコードに挿入することに成功しました。 #pragma GCC section text ".itcm_text" static void Motor_Drive_Subsystem(void) ヤージュ .......... } #pragma GCC セクション テキスト "" しかし、アプリケーションをコンパイルする際には、gccはこれらのプラグマ文を無視し、コードを標準の.textに配置しますセグメント。これはobjdumpコマンドで結論づけられます: arm-none-eabi-objdump -h Motor_Control.o (being the .oMotor_Drive_Subsystem関数を含むcファイルから生成されたファイル） .itcm_text はありませんリストには、.text.xxxx セグメントのみが含まれています (他の非テキストセグメントの中に)。 コンパイル時には、MBDT環境で設定された標準のGCCスイッチを使用しています。 arm-none-eabi-gcc -O2 -c -std=c99 -fshort-enums -funsigned-char -fstack-usage -ffunction-sections -fdata-sections -g -pedantic -Wall -Wextra -fmessage-length=0 -funsigned-bitfields -fno-common -Wunused -Wstrict-prototypes -Wsign-compare -Werror=implicit-function-declaration -mcpu=cortex-m7 -mthumb -mlittle-endian -mfloat-abi=hard -mfpu=FPV5-sp-d16 -DD_CACHE_ENABLE -DI_CACHE_ENABLE -specs=nano.specs -specs=nosys.specs --sysroot="C:\MATLAB_Add-Ons\Toolboxes\NXP_MBDToolbox_S32K3\tools\build_tools\gcc_v10.2\gcc-10.2-arm32-eabi\arm-none-eabi\newlib」-DSTEP_GPT_TIMER -DSTEP_GPT_CHANNEL=GptConf_GptChannelConfiguration_StepTimer -DSTEP_GPT_CHANNEL_FREQ=40000000 -DSTEP_GPT_CHANNEL_VALUE_MAX=4294967295 -DAUTOSAR_OS_NOT_USED -D__MW_TARGET_USE_HARDWARE_RESOURCES_H__ -DGCC -DS32K3XX -DS32K396 -DCPU_S32K396 -DENABLE_FPU -DMPU_ENABLE -DMBDT_INIT -DCLASSIC_INTERFACE=0 -DALLOCATIONFCN=0 -DTERMFCN=0 -DONESTEPFCN=1 -DMAT_FILE=0 -DMULTI_INSTANCE_CODE=0 -DINTEGER_CODE=0 -DMT=0 -DTID01EQ=0 -DSTACK_SIZE=64 -DRT -DMODEL=Motor_Control -DNUMST=1 -DNCSTATES=0 -DHAVESTDIO -DMODEL_HAS_DYNAMICALLY_LOADED_SFCNS=0 -IC: ..... 生成されたcコードファイルを修正し、手動でコンパイルすることで、次の結論が得られます。 関数の「static」宣言を削除しても効果はありません。しかし、「static」を削除し、関数に属性ステートメントを追加するという別の方法を使用すると、次のようになります。 static void  __attribute__((section(".itcm_text")))Motor_Drive_Subsystem(void); .itcm_textを作成します.o のセグメントファイル。 私が何か間違ったことをしているのか、それともツールに問題があるのか、よく分かりません。 これをうまく動かす方法を誰か教えてもらえますか? もちろん、ツールチェーンにこの処理を任せたいので、コード生成後にCコードを手動で修正したくはありません。 私の見る限り、startup_cm7.Sのようですまた、ITCMおよびDTCMメモリを処理するためにlinker_flash_s32k396.ldファイルが用意されています。 フォーラムでこの投稿を見つけました。関連性があるかどうかはわかりませんが、こちらです： https://community.nxp.com/t5/S32-Design-Studio/No-GCC-11-4-item-in-new-project-wizard-dialog-on-S32DS-3-6-2/td-p/2134523 MBDTのgccはビルド1728のようですが、投稿で修正されているものはビルド1803です。 よろしくお願いいたします！ Re: Gcc ignoring pragma statements to place code into ITCM memory. こんにちは、 カスタムストレージクラスの設定方法については、MathWorksのウェブサイトにある以下のページをご確認ください。プラグマを挿入することによって、メモリ内のデータと関数の配置を制御する。 使用する必要がある部分は、「サブシステム機能とデータのデフォルトメモリ配置を上書きする」です。 SorinIBancila_0-1786627722302.pngSorinIBancila_0-1786627722302.pngSorinIBancila_0-1786627722302.pngSorinIBancila_0-1786627722302.png カスタムストレージクラスを作成した後は、モデルを読み込むように設定する必要があります: 0. カスタムストレージクラスの作成および構成: SorinIBancila_5-1786628332348.pngSorinIBancila_5-1786628332348.pngSorinIBancila_5-1786628332348.pngSorinIBancila_5-1786628332348.png 1. コードパースペクティブに入る SorinIBancila_1-1786628013296.pngSorinIBancila_1-1786628013296.pngSorinIBancila_1-1786628013296.pngSorinIBancila_1-1786628013296.png 2. オープン組み込みコーダー辞書(モデル) SorinIBancila_2-1786628097732.pngSorinIBancila_2-1786628097732.pngSorinIBancila_2-1786628097732.pngSorinIBancila_2-1786628097732.png 3. 先ほど作成したカスタムクラスを読み込みます。 SorinIBancila_3-1786628212316.pngSorinIBancila_3-1786628212316.pngSorinIBancila_3-1786628212316.pngSorinIBancila_3-1786628212316.png 4. モデル内で新しいサブシステムを作成し、それを原子に設定します。 SorinIBancila_6-1786628433580.pngSorinIBancila_6-1786628433580.pngSorinIBancila_6-1786628433580.pngSorinIBancila_6-1786628433580.png 5. コード生成内で、実行関数のメモリセクションをカスタムクラスで設定されている「MemSection_ITCM」に設定します。 SorinIBancila_7-1786628826071.pngSorinIBancila_7-1786628826071.pngSorinIBancila_7-1786628826071.pngSorinIBancila_7-1786628826071.png 6. arm-none-eabi-objdump が.oを.itcm_textに読み込むときに正しくITCM_ToggleDIO植え替えメモリセクション SorinIBancila_8-1786631977524.pngSorinIBancila_8-1786631977524.pngSorinIBancila_8-1786631977524.pngSorinIBancila_8-1786631977524.png arm-none-eabi-nm -n s32k3xx_dio_s32ct.elfも、ITCM_ToggleDIOは0x0住所で見つかると言っています。 SorinIBancila_9-1786632086079.pngSorinIBancila_9-1786632086079.pngSorinIBancila_9-1786632086079.pngSorinIBancila_9-1786632086079.png もし.elfをS32DSからフラッシュし、内部でブレークポイントを使うと関数s32k3xx_dio_s32c_ITCM_ToggleDIO、逆アセンブルビューでは命令がアドレスから始まる0x0が確認できます。 SorinIBancila_0-1786632484317.pngSorinIBancila_0-1786632484317.pngSorinIBancila_0-1786632484317.pngSorinIBancila_0-1786632484317.png よろしくお願いします、 ソリン・バンシラ Re: Gcc ignoring pragma statements to place code into ITCM memory. こんにちは、ソリンさん 手伝ってくれてありがとう！ 私は実際にMathWorksのウェブサイトに掲載されていた指示に従っていました。 これで、プラグマ文の代わりに属性文を挿入する機能が動作するようになりました。 しかし、それでもgccは関数を.itcm_textに挿入することを拒否する。セグメント。 ブロックには以下のコード生成設定を使用します。 RNJ_0-1786705067074.pngRNJ_0-1786705067074.pngRNJ_0-1786705067074.pngRNJ_0-1786705067074.png 次のような関数のコードが生成されます。 /* 標準コード生成をITCMにリダイレクトする */ __attribute__ ((section(".itcm_text"))) static void Motor_Drive_Subsystem(void) { .... } 結論： .o に itcm_text セグメントがありませんファイル Gcc は関数を完全に最適化します (.o を逆アセンブルすると確認できます)ファイル） 生成された.cファイルから関数の「static」宣言を削除すると手動で再コンパイルすると、.itcm_text が取得できます。.o のセグメントファイル。 どうやら「static」宣言によって、gccコンパイラは属性プレフィックスを無視するようになるようです。 Modelsimでブロックを「再利用可能な関数」に設定すれば、静的宣言が削除されることを期待します。 RNJ_1-1786705067131.pngRNJ_1-1786705067131.pngRNJ_1-1786705067131.pngRNJ_1-1786705067131.png 私は以下を受け取ります： .itcm_text はまだありません.o のセグメントファイル 生成されたCコードでは、関数は依然として「static」として宣言されています。 .o の逆アセンブルファイルを見ると、gcc はアセンブリコード内に関数を保持しているが、.itcm_text への指示は見られない。セグメント では、「静的」宣言が問題なのか(Simulinkや組み込みコーダーの設定に関係しているのか)、それともGCCが「static」を優先して「attribute」宣言を優先している問題なのか?

Gcc 忽略 pragma 语句，将代码放入 ITCM 内存中。 您好！ 这里使用的是 Matlab R2025b、Simulink 和 MBDT for S32K3 版本 1.7.1。 为了优化我们正在开发的电机控制器应用程序的性能，我们希望将部分代码放入 ITCM 内存中，稍后将数据放入 DTCM 内存中。 目前，为了测试工作流程，我正在尝试将一个函数放入 ITCM 内存中。我成功地让 Simulink/嵌入式程序员将正确的编译指示语句插入到 C 代码中，例如： #pragma GCC 部分文本 ".itcm_text" static void Motor_Drive_Subsystem(void) { .......... } #pragma GCC 部分文本“” 然而，在编译应用程序时，gcc 会忽略这些编译指示语句，并将代码放置在标准的 .text 文件中。部分。可以用 objdump 命令得出结论： arm-none-eabi-objdump -h Motor_Control.o （即 .o 文件）由包含 Motor_Drive_Subsystem 函数的 c 文件生成的文件） 没有 .itcm_text列表中只有 .text.xxxx 段（以及其他非文本段）。 编译时，我使用 MBDT 环境中设置的 gcc 标准开关： arm-none-eabi-gcc -O2 -c -std=c99 -fshort-enums -funsigned-char -fstack-usage -ffunction-sections -fdata-sections -g -pedantic -Wall -Wextra -fmessage-length=0 -funsigned-bitfields -fno-common -Wunused -Wstrict-prototypes -Wsign-compare -Werror=implicit-function-declaration -mcpu=cortex-m7 -mthumb -mlittle-endian -mfloat-abi=hard -mfpu=fpv5-sp-d16 -DD_CACHE_ENABLE -DI_CACHE_ENABLE -specs=nano.specs -specs=nosys.specs --sysroot="C:\MATLAB_Add-Ons\Toolboxes\NXP_MBDToolbox_S32K3\tools\build_tools\gcc_v10.2\gcc-10.2-arm32-eabi\arm-none-eabi\newlib"-DSTEP_GPT_TIMER -DSTEP_GPT_CHANNEL=GptConf_GptChannelConfiguration_StepTimer -DSTEP_GPT_CHANNEL_FREQ=40000000 -DSTEP_GPT_CHANNEL_VALUE_MAX=4294967295 -DAUTOSAR_OS_NOT_USED -D__MW_TARGET_USE_HARDWARE_RESOURCES_H__ -DGCC -DS32K3XX -DS32K396 -DCPU_S32K396 -DENABLE_FPU -DMPU_ENABLE -DMBDT_INIT -DCLASSIC_INTERFACE=0 -DALLOCATIONFCN=0 -DTERMFCN=0 -DONESTEPFCN=1 -DMAT_FILE=0 -DMULTI_INSTANCE_CODE=0 -DINTEGER_CODE=0 -DMT=0 -DTID01EQ=0 -DSTACK_SIZE=64 -DRT -DMODEL=Motor_Control -DNUMST=1 -DNCSTATES=0 -DHAVESTDIO -DMODEL_HAS_DYNAMICALLY_LOADED_SFCNS=0 -IC: ..... 通过修改生成的 C 代码文件并手动编译，我可以得出以下结论： 移除函数的“static”声明并不能解决问题。然而，移除“static”并使用另一种方法，即在函数上添加属性语句： static void __attribute__((section(".itcm_text")))Motor_Drive_Subsystem(void); 将创建一个 .itcm_text.o 段文件。 我不确定是我操作有误还是工具出了问题。 请问有人能指导我如何才能让它正常运行吗？ 当然，我们希望工具链能够处理这种情况，而不希望在代码生成后手动修改 C 代码。 据我所见，它看起来像是 startup_cm7.s。并准备了 linker_flash_s32k396.ld 文件来处理 ITCM 和 DTCM 存储器。 我在论坛上找到了这篇帖子，不确定是否与此相关： https://community.nxp.com/t5/S32-Design-Studio/No-GCC-11-4-item-in-new-project-wizard-dialog-on-S32DS-3-6-2/td-p/2134523 MBDT gcc 的版本似乎是 1728，而帖子中修复的版本是 1803。 提前感谢！ Re: Gcc ignoring pragma statements to place code into ITCM memory. 你好， 请查看 MathWorks 网站上的以下页面，了解如何设置自定义存储类：通过插入编译指示来控制数据和函数在内存中的位置。 您需要使用的部分是“覆盖子系统功能和数据的默认内存放置”。 SorinIBancila_0-1786627722302.pngSorinIBancila_0-1786627722302.pngSorinIBancila_0-1786627722302.pngSorinIBancila_0-1786627722302.png 创建自定义存储类后，必须配置模型以加载它： 0. 创建并配置自定义存储类： SorinIBancila_5-1786628332348.pngSorinIBancila_5-1786628332348.pngSorinIBancila_5-1786628332348.pngSorinIBancila_5-1786628332348.png 1. 进入代码透视图 SorinIBancila_1-1786628013296.pngSorinIBancila_1-1786628013296.pngSorinIBancila_1-1786628013296.pngSorinIBancila_1-1786628013296.png 2. 开放式嵌入式编码器字典（模型） SorinIBancila_2-1786628097732.pngSorinIBancila_2-1786628097732.pngSorinIBancila_2-1786628097732.pngSorinIBancila_2-1786628097732.png 3. 加载你之前创建的自定义类。 SorinIBancila_3-1786628212316.pngSorinIBancila_3-1786628212316.pngSorinIBancila_3-1786628212316.pngSorinIBancila_3-1786628212316.png 4. 在模型内部，创建一个新的子系统并将其设置为原子级。 SorinIBancila_6-1786628433580.pngSorinIBancila_6-1786628433580.pngSorinIBancila_6-1786628433580.pngSorinIBancila_6-1786628433580.png 5. 在代码生成中，设置执行函数的内存部分：“MemSection_ITCM”，如自定义类中设置的那样。 SorinIBancila_7-1786628826071.pngSorinIBancila_7-1786628826071.pngSorinIBancila_7-1786628826071.pngSorinIBancila_7-1786628826071.png 6. arm-none-eabi-objdump 正确报告 ITCM_ToggleDIO.o 已加载到 .itcm_text 中存储器部分 SorinIBancila_8-1786631977524.pngSorinIBancila_8-1786631977524.pngSorinIBancila_8-1786631977524.pngSorinIBancila_8-1786631977524.png arm-none-eabi-nm -n s32k3xx_dio_s32ct.elf 还指出，ITCM_ToggleDIO 位于 0x0 地址。 SorinIBancila_9-1786632086079.pngSorinIBancila_9-1786632086079.pngSorinIBancila_9-1786632086079.pngSorinIBancila_9-1786632086079.png 如果从 S32DS 烧录 .elf 文件，并在s32k3xx_dio_s32c_ITCM_ToggleDIO 函数内部使用断点，则在反汇编视图中我们可以看到指令是从 0x0 地址开始存储的。 SorinIBancila_0-1786632484317.pngSorinIBancila_0-1786632484317.pngSorinIBancila_0-1786632484317.pngSorinIBancila_0-1786632484317.png 此致， 索林·班奇拉 Re: Gcc ignoring pragma statements to place code into ITCM memory. 索林你好 谢谢你的帮助！ 我当时确实是按照 Mathworks 网站上的说明操作的。 现在我已经实现了用属性语句代替编译指示语句插入数据的功能。 但是，gcc 仍然拒绝将该函数放入 .itcm_text 文件中。部分。 我使用以下代码块生成设置： RNJ_0-1786705067074.pngRNJ_0-1786705067074.pngRNJ_0-1786705067074.pngRNJ_0-1786705067074.png 为如下函数生成的代码： /* 将标准代码生成重定向到 ITCM */ __attribute__ ((section(".itcm_text"))) static void Motor_Drive_Subsystem(void) { .... } 结论： .o 文件中不存在 itcm_text 段。文件 Gcc 完全优化掉了这个函数（可以通过反汇编 .o 文件看到）。文件） 如果我移除生成的 .c 文件中函数的“static”声明手动重新编译后，我将得到 .itcm_text 文件。.o 段文件。 看起来“static”声明导致gcc编译器忽略了属性前缀。 如果我在 Modelsim 中将该代码块设置为“可重用函数”，希望这样可以移除静态声明： RNJ_1-1786705067131.pngRNJ_1-1786705067131.pngRNJ_1-1786705067131.pngRNJ_1-1786705067131.png 我得到： 仍然没有 .itcm_text.o 段文件 生成的 C 代码中，该函数仍然声明为“静态”函数。 .o 文件的反汇编文件显示 gcc 保留了汇编代码中的函数，但没有迹象表明它指向 .itcm_text 文件。部分 那么，问题是“static”声明（Simulink 或嵌入式编码器中的设置）还是 gcc 优先使用“static”声明而不是“attribute”声明？ 顺祝商祺！ Re: Gcc ignoring pragma statements to place code into ITCM memory. 你好， 我很高兴你解决了这个问题！ 😄 此致， 索林·班奇拉 Re: Gcc ignoring pragma statements to place code into ITCM memory. 啊哈！ 既然“static”声明是导致我问题的原因，我查看了配置参数中的代码生成部分，发现了以下内容： RNJ_0-1786969749323.pngRNJ_0-1786969749323.pngRNJ_0-1786969749323.png 取消勾选后问题就解决了！ 没有静态声明函数，但我可以在映射文件中看到 itcm_text 段。如果你也认为这是最佳解决方案，我就满意了。 谢谢你的帮助，非常感谢！ Re: Gcc ignoring pragma statements to place code into ITCM memory. 你好， 我尝试重现您遇到的问题，生成的函数不包含“static”关键字。 SorinIBancila_0-1786963037855.pngSorinIBancila_0-1786963037855.png 为了进行测试，我加载了一个基本示例（s32k3xx_dio_s32ct），并将所有模块移动到一个子系统中，将其配置为原子操作，并使用 MemSection_ITCM 定义。你能试着也这样做吗？如果这种情况没有重现，可能是你的模型中某些设置强制生成的函数是静态的。 此致， 索林·班奇拉

LAN96455F 以太网交换机与 i.MX95 集成 – 设备树指南 您好，NXP团队： 我们正在将Microchip LAN96455F以太网交换机（LAN9645x系列）集成到定制的i.MX95 19x19 LPDDR5板（基于imx95-19x19-evk.dts）上，我希望得到关于正确集成设备树的指导。 Re: LAN96455F Ethernet Switch Integration with i.MX95 – Device Tree Guidance 对于 Linux，如果您希望 Linux 单独公开/管理外部交换机端口，请将 LAN96455F 建模为DSA 以太网交换机。连接到交换机 CPU/上行链路端口的 i.MX95 ENETC/NETC 以太网 MAC 应该是 DSA通道接口；LAN96455F 端口成为 DSA 用户网络设备。DSA 专为具有连接到 SoC 以太网控制器的专用 CPU 端口的交换机而设计，它为每个前面板创建“用户”界面，而不是为 CPU 端口本身创建单独的网络设备。 一个好的设备树结构是： /* 将 &enetX / &mdioX 替换为实际使用的 i.MX95 BSP 标签 * 在 imx95-19x19-evk.dts / imx95.dtsi 中，选择您喜欢的 NETC ENETC 端口。 */ /* i.MX95 ENETC 端口连接到 LAN96455F CPU/上行链路端口 */ &netX { 状态 = "好的" /* 必须匹配 i.MX95 和 LAN96455F 之间的电气接口： * "rgmii-id", "rgmii", "sgmii", "2500base-x", 等。 */               phy-mode = "rgmii-id"; /* MAC 到交换机的 CPU 端口通常是无 PHY 的，因此请对其进行描述 *除非 LAN96455F CPU 端口实际处于固定链路状态，否则不会作为固定链路使用 * 通过 PHY/PCS 进行管理。 */ 固定链接 { 速度 = <1000> 全双工；               }; }; /* MDIO 控制器用于访问交换机管理接口。 * i.MX95 NETC 具有用于外部 PHY 的外部主 MDIO 接口， * 支持第 22 条和第 45 条 。 */ &mdioX { 状态 = "好的" 以太网交换机@0 { /* 使用 LAN9645x 驱动程序/绑定中的兼容字符串 * 已包含在您的内核/BSP 中。不要编造这个字符串。 */ 兼容 = "microchip, " reg = <0>; /* 板上绑定的 MDIO 地址 */ 端口 { #address-cells = <1> #size-cells = <0> port@0 { reg = <0> 标签 = "lan0" /* 如果此外部端口具有外部 PHY： * phy-handle = * phy-mode = "..." */ }; port@1 { reg = <1> 标签 = "lan1" }; port@2 { reg = <2> 标签 = "lan2" }; port@3 { reg = <3> 标签 = "lan3" }; /* LAN96455F CPU/上行链路端口号必须与 * Microchip 数据手册/驱动程序定义。 */                                            端口@N { reg = 标签 = "cpu" 以太网 = <&enetX>;                                                            phy-mode = "rgmii-id"                                                                 固定链接 { 速度 = <1000> 全双工; }; }; };               }; }; 最终确定DTS之前需要检查的关键点： 使用内核中的实际 LAN9645x 绑定。我无法从检索到的源中确认公共主线 LAN96455F 特定绑定，因此上面的兼容字符串故意用作占位符。检查 NXP 电路板支持包/Microchip 驱动程序树，路径为 Documentation/devicetree/bindings/net/dsa/ 或 Microchip LAN9645x 驱动程序源代码。 在交换机 CPU 端口上设置 ethernet = <&enetX>;，而不是在每个交换机端口上设置。DSA 端口绑定表示以太网属性是交换机端口所连接的主机以太网设备的句柄。 CPU/DSA 端口需要 phylink 风格的链路描述。对于以太网 = <&enetX>; 的 CPU 端口，绑定需要 phy-mode 和 fixed-link、phy-handle 或 managed 之一。 使用固定链路实现 MAC 地址到交换机 CPU 端口的直接连接。通用以太网绑定定义了具有速度、全双工和可选的暂停属性的固定链路；支持的固定链路速度包括对象形式的 10/100/1000/2500/5000/10000 Mbit/s。 使用RGMII延迟模式时要精确控制。phy-mode = "rgmii-id" 表示 PCB 不提供 RGMII 时钟/数据延迟，MAC/PHY 端必须提供内部延迟；plain "rgmii" 表示 PCB 布线提供延迟。对于大多数自定义电路板而言，“rgmii-id”是预期的起点，除非您的布局特意添加了延迟。 如果 MAC 连接到交换机 CPU 端口，则不要将 i.MX95 MAC 配置为具有普通外部 PHY 。在 DSA 模型中，MAC 是通道，外部用户端口由交换机端口节点表示。 预计会出现 lan0、lan1 等 Linux 接口。DSA为前面板端口创建用户网络设备，DSA 标签属性将成为网络设备名称。 出院检查： dmesg | grep -i -E "dsa|lan964|mdio|enetc|netc" IP链接 cat /sys/class/net/ /dsa/tagging 2>/dev/null ip 链路已设置 已启动 ip link set lan0 up ethtool lan0 如果没有 lanX 接口出现，请按以下顺序进行调试：MDIO 地址/strap 值、重置 GPIO 时序、如果驱动程序需要中断 GPIO、正确的 LAN9645x 兼容、正确的 CPU 端口寄存器以及 i.MX95 和交换机之间的正确 phy 模式/固定链路速度。 使用 i.MX95 ENETC 端口作为 DSA 通道，在 MDIO/SPI 管理总线下使用端口块描述 LAN96455F，并使交换机 CPU 端口指向 ENETC MAC，使用 ethernet = <&enetX> 加上有效的 phy-mode 和 fixed-link / managed / phy-handle。

NXP S32K312 CAN0 – FIRC vs. FXOSC クロックソースによる CAN エラーの発生 こんにちは、皆さん 私はS32K312でCAN0を使用し、500kbpsの速度で87.5%のサンプリングポイントを設定しています。 最初は、CAN0を内部のFIRC_CLKをクロックソースとして使用するように設定しました。S32K312を複数のCANノードがあるネットワークに接続したところ、多くのCANエラーフレームに気付きました。 その後、CANのクロックソースをFIRC_CLKから外部FXOSC_CLKに切り替え、CANのビットレートとサンプリングポイントは同じにしました。この変更後、通信は安定し、エラーフレームが表示されなくなりました。 なぜクロックソースをFIRC_CLKからFXOSC_CLKに切り替えるとCANエラーが直るのか、どなたか教えてもらえますか? Re: NXP S32K312 CAN0 – FIRC vs. FXOSC Clock Source Causing CAN Errors こんにちは、 @Karthik_R さん。 通常、FIRCクロックはFlexCAN通信には推奨されません。なぜなら、精度がCANプロトコル(ISO 11898-1)の~1%要件を超えているためです。S32K3のデータシートを見ると、FIRCの偏差は+-5%です。 FXOSCを使用するか、XOSCから実行されるPLLを使用することを推奨します。FlexCANビットタイミング計算のドキュメントや、MPC5xxx/S32Kxx/LPCxxxx: CAN / CAN FDビットタイミング計算ツールをご参照ください。 これで分かりやすくなったでしょうか。 よろしくお願いします、 ジュリアン

Gcc ignoring pragma statements to place code into ITCM memory. Hello! Using Matlab R2025b, Simulink and MBDT for S32K3 version 1.7.1 here. To optimize the performance of a motor controller application we are developing we want to place some parts of the code into the ITCM memory and later on, DTCM memory for data. As for now, for testing the workflow, I am trying to get a function placed into ITCM memory. I managed to get Simulink/ embedded coder to place the correct pragma statements in to the c code like: #pragma GCC section text ".itcm_text" static void  Motor_Drive_Subsystem(void) { .......... } #pragma GCC section text "" However, when compiling the application gcc ignore these pragma statements and places the code in the standard .text segment. This can be concluded with The objdump command: arm-none-eabi-objdump -h Motor_Control.o      (beeing the .o file generated from the c-file containing the Motor_Drive_Subsystem function) There are no .itcm_text in the list just .text.xxxx segments (among the other non text segments). When compiling I use the standard switches for gcc set by the MBDT environment: arm-none-eabi-gcc -O2 -c -std=c99 -fshort-enums -funsigned-char -fstack-usage -ffunction-sections -fdata-sections -g -pedantic -Wall -Wextra -fmessage-length=0 -funsigned-bitfields -fno-common -Wunused -Wstrict-prototypes -Wsign-compare -Werror=implicit-function-declaration -mcpu=cortex-m7 -mthumb -mlittle-endian -mfloat-abi=hard -mfpu=fpv5-sp-d16 -DD_CACHE_ENABLE -DI_CACHE_ENABLE -specs=nano.specs -specs=nosys.specs --sysroot="C:\MATLAB_Add-Ons\Toolboxes\NXP_MBDToolbox_S32K3\tools\build_tools\gcc_v10.2\gcc-10.2-arm32-eabi\arm-none-eabi\newlib" -DSTEP_GPT_TIMER -DSTEP_GPT_CHANNEL=GptConf_GptChannelConfiguration_StepTimer -DSTEP_GPT_CHANNEL_FREQ=40000000 -DSTEP_GPT_CHANNEL_VALUE_MAX=4294967295 -DAUTOSAR_OS_NOT_USED -D__MW_TARGET_USE_HARDWARE_RESOURCES_H__ -DGCC -DS32K3XX -DS32K396 -DCPU_S32K396 -DENABLE_FPU -DMPU_ENABLE -DMBDT_INIT -DCLASSIC_INTERFACE=0 -DALLOCATIONFCN=0 -DTERMFCN=0 -DONESTEPFCN=1 -DMAT_FILE=0 -DMULTI_INSTANCE_CODE=0 -DINTEGER_CODE=0 -DMT=0  -DTID01EQ=0 -DSTACK_SIZE=64 -DRT -DMODEL=Motor_Control -DNUMST=1 -DNCSTATES=0 -DHAVESTDIO -DMODEL_HAS_DYNAMICALLY_LOADED_SFCNS=0 -IC: ..... By modifying the generated c code file and manually compiling it I can conclude the following: Removing the “static” declaration of the function does not help. However, removing “static” and using the alternative way for this by adding an attribute statement on the function: static void  __attribute__((section(".itcm_text")))Motor_Drive_Subsystem(void); will create a .itcm_text segment in the .o file. I am not sure if I am doing something wrong here or if it is a tool problem. Can someone guide me on how to get this working? Of course, we want the tool chain to handle this and do not want to manually modify the c code after code generation. As far as I can see it looks like the startup_cm7.s and linker_flash_s32k396.ld files are prepared for handling the ITCM and DTCM memories. I found this post in the forum, not sure if it is relevant for this: https://community.nxp.com/t5/S32-Design-Studio/No-GCC-11-4-item-in-new-project-wizard-dialog-on-S32DS-3-6-2/td-p/2134523 The MBDT gcc seems to be build 1728 where as the fixed one in the post is build 1803.

Hi Sorin Thanks for helping out! I was actually following those instructions at Mathworks web site. Now I have the insertion of attribute statements instead of pragma statements working. But still, gcc refuses to put the function into the .itcm_text segment.

Can you try to do the same? If it doesn't reproduce in this scenario, maybe there are some setting in your model that force the generated function to be static. Best regards, Sorin Bancila Re: Gcc ignoring pragma statements to place code into ITCM memory. Hello, I am glad that you were able to solve the problem! 😄 Best regards, Sorin Bancila Re: Gcc ignoring pragma statements to place code into ITCM memory. Aha! Nowing that the "static" declaration is reason for my problems I had a look at the code generation section in configuration parameters and found this: RNJ_0-1786969749323.pngRNJ_0-1786969749323.png Unticking it solved the problem! No static declaration of the function(s) and I can see the itcm_text segment in the mapping file. I you also think this is the solution I am sattisfied. Thanks for the help, much appreciated!

FS23 V1 output abnormal V1 output is abnormal as below waveform: C1 was VSUP,C2 was VBOS,C3 was V2;C4 was V1(power to MCU)C1 was VSUP,C2 was VBOS,C3 was V2;C4 was V1(power to MCU) 微信图片_20260813093846_286_23.jpg V1 without npnV1 without npn 微信图片_2026-08-13_095130_111.png How can I thoroughly solve the problems I am currently facing? if you want to get more information,please let me know. Re: FS23 V1 output abnormal guoweisun_0-1786680381549.png guoweisun_1-1786680552393.png This diagram explains the softstart conditions highlighted above. If all conditions are met, V1 starts powering on and enters the M5 timing sequence, which takes 150-500µs. If the startup fails within this time, it enters the FS state and restarts after 100ms. This is roughly the process. Re: FS23 V1 output abnormal Could you please explain the softstart process? This section, " 19.4.6 V1UVLP monitoring chapter shows 'V1 is also monitored for V1UVLP when the device powers up after a wake-up from LPON, and during a cold start after TSOFT_START_V1. If, at the end of the softstart, V1 is still under the V1UVLP threshold, then the device goes into Fail-Safe state.'" What exactly is required for the V1 startup waveform? Thanks Re: FS23 V1 output abnormal This problem is most likely caused by V1 experiencing a startup failure during the soft boot process of OC, followed by a recovery. The solution is to add an external tube to the V1 port and enable this function when using FS23 OTP, or you can choose our HVBUCK version. Alternatively, you could remove some output capacitors to make the softstart smoother. I recommend choosing either of these two solutions for greater stability. Re: FS23 V1 output abnormal 1: If PIN37 in the schematic is not used, ground it. 2: V1's load current is not large, only a maximum of 100mA. Please confirm the load at your location. 3: The decoupling capacitor of V1_IN is 1uF. guoweisun_0-1786671133675.png 4: In the case above, if the first startup fails and the second startup occurs, can the register M_GEN_FLAG be read to see what happened? Let's change these things first and see the results. Re: FS23 V1 output abnormal We measured a new waveform and found that V1 sometimes fails to start on the first try when the input is 12V. af12f0f0-afa6-40e3-881d-890516697b5a.png This is the waveform of the first startup failure. V1第一次启动未成功图V1 failed to start on the first attempt (image) This is the waveform of the second successful startup. V1第二次启动成功图V1 successfully started for the second time (image) Is this related to the undervoltage detection in V1 after a soft boot? The typical soft boot time is 300µs, and the maximum is 500µs. Why does it seem like it won't boot if it exceeds 500µs, but it seems to work if it's below 500µs? Could you please describe the soft boot process? The manual doesn't provide much information about it. Re: FS23 V1 output abnormal guoweisun_0-1786608712650.png With 8V Vin, could you reduce the time axis of the waveform circled above? I want to see how long V1 has been running. Can we also test the same waveform with 12V VIN? I don't have a high and low temperature test chamber here, so I can't do too many tests. I can only rely on your results. Re: FS23 V1 output abnormal You can see below circled part. guoweisun_0-1786601658488.png Re: FS23 V1 output abnormal Channel 1 was VSUP,C2 was VBOS,C3 was V2;C4 was V1(power to MCU) Re: FS23 V1 output abnormal which one indicate V1 follow up VBAT from 0? current test results show VBOS>3.06V TO V1 UPing used 13.2ms, please check Re: FS23 V1 output abnormal guoweisun_0-1786601048119.png guoweisun_1-1786601077374.png A lots of confuse for your test result ,you can see when Vbat< Vsup_uv,the V1 should be stay 0,why your V1 follow up VBAT from 0? I suppose your test waveform yellow is VBAT,Green is V1,am I right? Re: FS23 V1 output abnormal This is testing. by the way, we check the manual and found 19.4.6 V1UVLP monitoring chapter shows "V1 is also monitored for V1UVLP when the device powers up after a wake up from LPON, and during a cold start after TSOFT_START_V1. If, at the end of the softstart, V1 is still under V1UVLP threshold, then the device goes into Fail-Safe state." does it mean V1 should beyond V1UVLP threshold after TSOFT_START_V1(type,300us)? in addition ,this V1 abnormal issue happened in low temperature (-30℃ ） and low Vsup power(8v)。in this condition, we increased VSUP to 12V，V1 output OK。 Re: FS23 V1 output abnormal VBOS>3.06V TO V1 UPing used 13.2msVBOS>3.06V TO V1 UPing used 13.2ms Re: FS23 V1 output abnormal You can try to disconnect  MCU with V1 and test it again for example add some loading 50mA.

If, at the end of the softstart, V1 is still under V1UVLP threshold, then the device goes into Fail-Safe state."”到底是要求什么样的V1启动波形？ 谢谢 Re: FS23 V1 output abnormal 这个问题大概率是V1 发生了OC在软启动的过程中导致启动失败然后又恢复的这个过程。 解决方案可以外加管子阔流在V1端口然后FS23 OTP的时候把这个功能打开，也可以选择我们的HVBUCK的版本。 要么就是适当的去掉一些输出电容让softstart更顺畅，我建议选择上面两个方案更稳妥 Re: FS23 V1 output abnormal 1：原理图PIN37不用的话接地。 2：V1的负载电流不大的最大才100mA确认下您那里的负载 3：V1_IN的decouple 电容是1uF. guoweisun_0-1786671133675.png 4: 就像上面这个情况第一次启动不成功第二次起来了能否读取寄存器 M_GEN_FLAG register 看看发生了什么？ 先改上面这些看看结果。 Re: FS23 V1 output abnormal 我们新测了个波形，在输入12V时也发现V1有时第一次启动是失败的。 af12f0f0-afa6-40e3-881d-890516697b5a.png 这是第一次启动失败的波形 V1第一次启动未成功图V1第一次启动未成功图 这是第二次启动成功的波形 V1第二次启动成功图V1第二次启动成功图 这个是不是和那个V1 在软启动之后的欠压检测有关联，但是软启动的时间是典型值300，最大值500us。现在为啥感觉是超过500us就启动不起来，低于500us好像就行。 能否帮忙描述下软启动的内容，看手册没有太多描述 Re: FS23 V1 output abnormal guoweisun_0-1786608712650.png 在8V Vin的情况下能否把这个上面圈出来的波形的时间轴放小些，我想看V1启动了多久？ 另外12V VIN的情况下也测试下相同的波形可以嘛？ 我这里没有高低温试验箱无法做太多的测试只能看你们的结果了。 Re: FS23 V1 output abnormal 您可以看到下面圈出的部分。 guoweisun_0-1786601658488.png Re: FS23 V1 output abnormal 通道 1 为 VSUP，C2 为 VBOS，C3 为 V2；C4 为 V1（MCU 电源） Re: FS23 V1 output abnormal 哪个指标表示 V1 后续 VBAT 从 0 开始？ 当前测试结果显示 VBOS>3.06VV1 更新耗时 13.2 毫秒，请检查 Re: FS23 V1 output abnormal guoweisun_0-1786601048119.png guoweisun_1-1786601077374.png 你的测试结果有很多令人困惑的地方。你可以看到，当 Vbat < Vsup_uv 时，V1 应该保持为 0，为什么你的 V1 会跟随 VBAT 从 0 开始变化呢？我猜你的测试波形中，黄色代表 VBAT，绿色代表 V1，对吗？ Re: FS23 V1 output abnormal 这是测试。 顺便说一下，我们查阅了手册，发现 19.4.6 V1UVLP 监测章节显示“当设备从 LPON 唤醒后上电，以及在 TSOFT_START_V1 之后冷启动时，也会监测 V1UVLP。如果在软启动结束时，V1 仍然低于 V1UVLP 阈值，则设备进入故障保护状态。 这是否意味着在 TSOFT_START_V1(type,300us) 之后，V1 应该超过 V1UVLP 阈值？ 此外，V1的异常问题发生在低温（-30℃）和低Vsup功率（8V）下。在这种情况下，我们将VSUP提高到12V，V1输出正常。 Re: FS23 V1 output abnormal VBOS>3.06V TO V1 UPing used 13.2msVBOS>3.06V 至 V1 UPing 耗时 13.2ms Re: FS23 V1 output abnormal 您可以尝试断开MCU与V1的连接，然后再次进行测试，例如增加50mA的负载。

ノズルでMPXM2053GSをピックアップする方法 SMTプロセス中、ピックアンドプレースノズルから圧力ポートに空気が吹き込まれる可能性があります。内部のセンサを壊すことはあり得ますか? Re: how to pick up MPXM2053GS by nozzle こんにちは、デイビッドさん。 ピックアンドプレースノズルから側面の圧力ポートへ短時間で低圧の空気パルスが噴射されても、印加される圧力がデバイスの最大定格過圧を超えない限り、損傷を引き起こす可能性は低い。しかし、繰り返しまたは高圧の空気吹きは原理的にダイアフラムにストレスを与えたり、極端な条件下では損傷を与える可能性があります。 リスクを完全に回避するために推奨される方法は、ピックアンドプレースノズルをM-PAKパッケージの平らな上部表面、側面圧力ポートから離れた位置に配置することです。これにより、ノズルがセンサーポートの開口部に空気の流れを接触したり、導いたりすることがなくなります。アプリケーションノート AN1984 – フリースケール圧力センサの取り扱い は、このデバイスファミリのノズル設計と配置に関する具体的な指針を提供し、MPXシリーズセンサのSMT取り扱いに関する主要な参考資料です。応用ノート AN936 – MPXシリーズ圧力センサの取り付け技術、リード成形および試験 も有用な補完資料です。 なお、2026年2月2日現在、NXP MEMSセンサー製品(MPXM2053GSを含む)はSTMicroelectronicsに移行されました。今後の継続的な製品サポートやドキュメント管理については、STMに直接相談することをお勧めします。 BRs、トーマス

FS23 V1 出力異常 V1出力は、以下の波形のように異常です。 C1 was VSUP,C2 was VBOS,C3 was V2;C4 was V1(power to MCU)C1はVSUP、C2はVBOS、C3はV2、C4はV1(power to MCU) 微信图片_20260813093846_286_23.jpg V1 without npnV1で、NPNなしで 微信图片_2026-08-13_095130_111.png 現在直面している問題をどうすれば徹底的に解決できるでしょうか? さらに詳しい情報が必要な場合は、お知らせください。 Re: FS23 V1 output abnormal guoweisun_0-1786680381549.png guoweisun_1-1786680552393.png この図は、上記で説明したソフトスタート条件を示しています。すべての条件が満たされると、V1は電源投入を開始し、150～500µsかかるM5タイミングシーケンスに入ります。この時間内に起動に失敗した場合、FS状態に入り、100ms後に再起動します。これが大まかなプロセスです。 Re: FS23 V1 output abnormal ソフトスタートのプロセスについて説明していただけますか？ このセクション「 19.4.6 V1UVLP モニタリングの章」には、「LPON からのウェイクアップ後、および TSOFT_START_V1 後のコールドスタート中に、デバイスの電源投入時にも V1 は V1UVLP について監視されます。ソフトスタートの終了時に V1 がまだ V1UVLP しきい値を下回っている場合、デバイスはフェイルセーフ状態になります。」と記載されています。V1の起動波形には具体的に何が必要ですか？ ありがとう Re: FS23 V1 output abnormal この問題は、OCのソフトブートプロセス中にV1が起動に失敗し、その後復旧したことが原因である可能性が最も高い。 解決策としては、V1ポートに外部チューブを追加し、FS23 OTP使用時にこの機能を有効にするか、弊社のHVBUCKバージョンを選択することです。 あるいは、出力コンデンサをいくつか取り外すことで、ソフトスタートをよりスムーズにすることもできます。安定性を高めるためには、これら2つの方法のいずれかを選択することをお勧めします。 Re: FS23 V1 output abnormal 1: 回路図のPIN37が使用されていない場合は、接地してください。 2：V1の負荷電流は大きくなく、最大でも100mAです。設置場所の負荷をご確認ください。 3：V1_INのデカップリングコンデンサは1μFです。 guoweisun_0-1786671133675.png 4：上記の場合、最初の起動が失敗し、2回目の起動が行われた場合、レジスタM_GEN_FLAGを読み取って何が起こったかを確認できますか？ まずはこれらの点を変えてみて、結果を見てみましょう。 Re: FS23 V1 output abnormal 新しい波形を測定したところ、入力電圧が12Vの場合、V1が初回起動時に失敗することがあることがわかりました。 af12f0f0-afa6-40e3-881d-890516697b5a.png これは最初の起動失敗時の波形です。 V1第一次启动未成功图V1は最初の試行で起動に失敗しました（画像）。 これは、2回目の起動が成功した際の波形です。 V1第二次启动成功图V1は2回目の起動に成功しました（画像）。 これはソフトブート後のV1における低電圧検出と関係があるのでしょうか？ 通常のソフトブート時間は300µs、最大は500µsです。500µsを超えると起動しないように見えるのに、500µs未満だと正常に動作するように見えるのはなぜでしょうか？ ソフトブートの手順について説明していただけますか？マニュアルにはあまり詳しい説明がありません。 Re: FS23 V1 output abnormal guoweisun_0-1786608712650.png 入力電圧が8Vの場合、上記の丸で囲んだ波形の時間軸を短くできますか？V1がどれくらいの時間動作しているかを確認したいのです。 12Vの入力電圧で同じ波形をテストすることもできますか？ ここに高温・低温試験室がないので、あまり多くの試験はできません。あなたの結果を頼りにするしかありません。 Re: FS23 V1 output abnormal 下記に丸で囲まれた部分が見えます。 guoweisun_0-1786601658488.png Re: FS23 V1 output abnormal チャネル1はVSUP、C2はVBOS、C3はV2でした。C4はV1(MCUへの電源)でした。 Re: FS23 V1 output abnormal どちらがV1が0からVBATに追随することを示していますか？ 現在のテスト結果では、VBOS>3.06Vとなっています。TO V1 UPing は 13.2ms 使用しました。ご確認ください。 Re: FS23 V1 output abnormal guoweisun_0-1786601048119.png guoweisun_1-1786601077374.png テスト結果が混乱します。Vbat< Vsup_uvが0のままでいるべきなのに、なぜV1は0から続くのでしょうか?テストの波形の黄色はVBAT、緑はV1、合っていますか? Re: FS23 V1 output abnormal これはテストです。 ちなみに、マニュアルを確認したところ、19.4.6 V1UVLP モニタリングの章に「LPON からのウェイクアップ後にデバイスの電源がオンになったとき、および TSOFT_START_V1 後のコールドスタート中に、V1 も V1UVLP 用に監視されます」と記載されていました。ソフトスタートの終了時にV1がV1UVLPしきい値を下回っている場合、デバイスはフェイルセーフ状態に移行します。 これは、TSOFT_START_V1(type,300us)の後、V1がV1UVLPのしきい値を超える必要があるという意味ですか？ さらに、このV1異常は低温（-30℃）および低Vsup電源（8V）の条件下で発生しました。この状況下でVsupを12Vに上げたところ、V1出力は正常になりました。 Re: FS23 V1 output abnormal VBOS>3.06V TO V1 UPing used 13.2msVBOS>3.06VからV1へのアップイングには13.2msかかりました。 Re: FS23 V1 output abnormal 例えば、V1のMCUを切断して再度テストしてみてください。例えば、50mAの負荷を追加してみてはどうでしょうか。

MCXA185 读取电位器的值 MCXA185 LPADC 电位器读数 – 寻找更稳定的 ADC 值 我正在使用NXP MCXA185 ，并使用 LPADC 读取连接到P2_0 / ADC0_A0 的电位器。 我目前的实现方式是： ADC0 / ADC0_A0 高分辨率转换模式 LPADC硬件平均128个样本 长ADC采样时间（kLPADC_SampleTimeADCK19） 每1 毫秒 (1000 Hz)读取一次 ADC 数据 软件触发的转化 100 个样本的块平均值 最终得到的平均值每100 毫秒更新一次。 因此，实际上，块平均值中使用的每个值都已经由 ADC 硬件在 128 次转换中进行了平均。 当前方法 cmdConfig.conversionResolutionMode = kLPADC_ConversionResolutionHigh; cmdConfig.hardwareAverageMode = kLPADC_HardwareAverageCount128; cmdConfig.sampleChannelMode = kLPADC_SampleChannelSingleEndSideA; cmdConfig.sampleTimeMode = kLPADC_SampleTimeADCK19; 然后每隔 1 毫秒： LPADC_DoSoftwareTrigger(POT_LPADC_BASE, (1U << POT_LPADC_TRIGGER_ID)); while (!LPADC_GetConvResult(POT_LPADC_BASE, &result)) { /* Wait for conversion */ } s_blockSum += result.convValue; s_sampleCount++; if (s_sampleCount >= 100U) { s_lastAverage = (uint16_t)(s_blockSum / 100U); s_blockSum = 0U; s_sampleCount = 0U; } 我的问题 这种方法能获得稳定的电位器值吗？还是有更好的ADC滤波/平均策略？ 我尤其想知道： 对于电位器来说，使用128 计数硬件平均 + 100 采样软件平均是否过量？ 这样做真的能有效降低噪音，还是只会增加响应延迟？ 使用较小的硬件平均值（例如 16 或 32 个样本），然后再使用软件滤波器，是否会更好？ 对于电位器来说， IIR/指数移动平均是否比100个样本的块平均值更好，因为它能提供更平滑的值，同时对旋钮的移动响应更快？ kLPADC_SampleTimeADCK19 是否适用于典型的电位器，还是我应该使用不同的采样时间？ 有没有什么MCXA185特定的LPADC设置需要启用以提升稳定性？ 在 1 毫秒的函数内轮询 ADC 结果是否是一种合理的实现方式，还是采用硬件定时器触发信号 + ADC FIFO/中断的方法更好？ 引脚配置 我目前正在使用： cfg.pullSelect = kPORT_PullDisable; cfg.driveStrength = kPORT_LowDriveStrength; cfg.passiveFilterEnable = true; cfg.inputBuffer = kPORT_InputBufferDisable; 电位器连接成分压器，滑动端连接到P2_0 / ADC0_A0 。 我主要想得到的值是： 当电位器不移动时，电路保持稳定。 当电位器转动时，会有反应。 不会因过度平均而造成不必要的延误 能抵抗较小的ADC/滑动噪声 我希望得到反馈，看看我目前采用的128 硬件平均值 + 100 样本块平均值方法是否合适，以及您会推荐哪种滤波策略用于此应用。 模拟（ADC|CMP|DAC|运算放大器） MCXA Re: MCXA185 Reading values of a potentiometer 你好， 请问您使用的是高速信道吗？您是以 SDK 中的示例为基础吗？ 您使用了较高的 AVGS 值。较高的平均转换次数有助于获得更稳定的响应，但如果您追求更平衡的响应，可以使用较小的 AVGS 值，例如 16 个样本 (0100)，这样可以在更低的转换时间内提供良好的噪声抑制。 在MCX-A-185 数据表中，图 11 和图 12 可以帮助您确定在高速模式下需要多少平均值。 kLPADC_SampleTimeADCK19 的具体使用取决于您的应用需求。对于低阻抗输入，最短的采样时间可以最大限度地提高转换速度。延长采样时间可以对更高阻抗的输入信号进行精确采样。如果您需要针对较低的阻抗（例如电位器）优化转换速度，则可以使用较短的采样时间，例如 kLPADC_SampleTimeADCK7。 如果您需要根据所需的精度计算所需的采样时间，可以参考数据表表 33 第 4.B 小节中的公式。 可能是MCX-A-18 参考手册第 45.5.1.2 章中关于 ADC 校准的说明。- 45.5.1.4正是你想要的。 顺祝商祺！

MCXA185 ポテンショメータの値の読み取り MCXA185 LPADCポテンショメータの読み取り – より安定したADC値を求めて NXP MCXA185を使って作業しており、LPADCを使ってP2_0/ADC0_A0に接続されたポテンショメーターを読み取っています。 私の現在の実装では以下を使用しています。 ADC0 / ADC0_A0 高解像度変換モード LPADCハードウェアによる128サンプルの平均化 長時間のADCサンプリング時間（kLPADC_SampleTimeADCK19） 1ミリ秒ごと（1000Hz）にADCの読み取り値を取得 ソフトウェアトリガー変換 100サンプルのブロック平均 結果として得られる平均値は100ミリ秒ごとに更新されます。 つまり、ブロック平均に使われる各値は、ADCハードウェアによって128回の変換で平均化されているのです。 現在のアプローチ cmdConfig.conversionResolutionMode = kLPADC_ConversionResolutionHigh; cmdConfig.hardwareAverageMode = kLPADC_HardwareAverageCount128; cmdConfig.sampleChannelMode = kLPADC_SampleChannelSingleEndSideA; cmdConfig.sampleTimeMode = kLPADC_SampleTimeADCK19; そして1ミリ秒ごとに： LPADC_DoSoftwareTrigger(POT_LPADC_BASE, (1U << POT_LPADC_TRIGGER_ID)); while (!LPADC_GetConvResult(POT_LPADC_BASE, &result)) { /* Wait for conversion */ } s_blockSum += result.convValue; s_sampleCount++; if (s_sampleCount >= 100U) { s_lastAverage = (uint16_t)(s_blockSum / 100U); s_blockSum = 0U; s_sampleCount = 0U; } 私の質問 これは安定したポテンショメータ値を得るための良い方法でしょうか、それとももっと優れたADCフィルタリング／平均化戦略があるでしょうか？ 特に、以下の点について疑問に思っています。 ポテンショメーターとして 128カウントのハードウェア平均+100サンプルのソフトウェア 平均を使うのは過剰でしょうか? これは実際に有用な追加のノイズ低減になれるのでしょうか?それとも単にレスポンスレイテンシを増やしているだけでしょうか? 16サンプルや32サンプルのような小さなハードウェア平均を使い、その後ソフトウェアフィルターを使う方が良いのでしょうか? ポテンショメータの場合、 IIR/指数移動平均は100サンプルブロック平均よりも優れているでしょうか？なぜなら、IIR/指数移動平均の方が、つまみの動きに素早く反応しつつ、より滑らかな値が得られるからです。 kLPADC_SampleTimeADCK19は一般的なポテンショメータに適していますか、それとも別のサンプリング時間を使用すべきでしょうか？ 安定性を向上させるために有効にすべき、MCXA185固有のLPADC設定はありますか？ 1ms関数内でADCの結果をポーリングする方法は妥当な実装でしょうか、それともハードウェアタイマートリガーとADC FIFO/割り込み方式を組み合わせた方が望ましいでしょうか？ ピン構成 現在使用しているもの： cfg.pullSelect = kPORT_PullDisable; cfg.driveStrength = kPORT_LowDriveStrength; cfg.passiveFilterEnable = true; cfg.inputBuffer = kPORT_InputBufferDisable; ポテンショメータは電圧分圧器として接続され、ワイパーは P2_0/ADC0_A0に接続されています。 私が主に知りたいのは、以下の値です。 ポテンショメータが動いていないときは安定している ポテンショメータを回すと反応する 過度の平均化による不必要な遅延がない 小さなADC/ワイパーノイズに耐性がある 現在の ハードウェア平均128+100サンプルブロック平均 のアプローチが適切かどうか、またこの用途にどのようなフィルタリング戦略を推奨するかについてフィードバックをいただけるとありがたいです。 アナログ(ADC|CMP|DAC|OpAmp) MCXA Re: MCXA185 Reading values of a potentiometer こんにちは、 高速チャネルを使っているか確認してもらえますか?SDKの例をベースに使っていますか? 高いAVGS値を使っていますが、変換値を平均すると応答が安定しますが、よりバランスの取れた応答を求めるなら、16サンプル(0100)の小さいAVGSを使うことで、変換時間を短縮して良いノイズ抑制が得られます。 MCX-A-185のデータシートでは、図11と図12が高速モードを考慮すると、どれだけ平均が必要なかの方向転換に役立ちます。 kLPADC_SampleTimeADCK19を使うかどうかは、あなたのアプリケーションミッションによります。最短のサンプリング時間は、低インピーダンス入力における変換速度を最大化します。サンプリング時間を延長することで、より高いインピーダンスの入力も正確にサンプリングできるようになる。ポテンショメータのようにインピーダンスを抑える変換速度を最適化したいなら、例えばサンプル時間を短くする方法kLPADC_SampleTimeADCK7。 必要なサンプル時間を望ましい精度を考慮して計算する必要がある場合は、データシート表33小節4.Bの公式を確認できます おそらく MCX-A-18リファレンスマニュアル 45.5.1.2章のADCキャリブレーションの説明書でしょう- 45.5.1.4あなたが探しているのはこれです。 よろしくお願いいたします。

S32K3系列MCU的DFARS原产国/合格国家合规性 大家好， 我正在评估 NXP S32K3 系列 MCU，用于一个需要符合 DFARS 标准的采购项目，我希望这里有人能帮我指明正确的方向，或者以前处理过类似的事情。 具体来说，我想确认的是： 特定 S32K3 零件编号的制造/组装国家/地区（晶圆厂和封装/测试地点）——合规性通常与零件是否在DFARS 252.225-7002（合格国家/地区来源作为分包商）规定的 DFARS“合格国家/地区”制造有关，因此我需要零件编号/封装级别的信息，而不是一般的“NXP 符合规定”声明。 NXP 能否为特定部件出具原产地证书 (COO)或正式的DFARS 合规声明。 是否有TAA 合规函可供参考，因为这可能也适用于我们的项目。 感兴趣的部分（也欢迎符合同一级别的其他选择）： S32K344 S32K358 S32K314 我们的目标是闪存容量≥512 kB、RAM容量≥128 kB的MCU，所以我主要关注的是内存容量更高的S32K3系列产品，但如果其他S32K3系列产品（或更广泛的S32K1/S32K2系列）在合规性方面有更好的文档记录，我也很乐意了解。 向社区提出的问题： 有没有人成功直接从NXP获得过S32K3部件的COO/DFARS文件？如果是的话，您是与哪些人员合作的（现场应用工程师、代理商、质量团队）？ NXP 是否会公布这些信息，还是总是根据零件/日期代码逐个申请？ 是否有特定的 S32K3 零件编号或包装已知来自符合 DFARS 资格的国家，而其他不符合 DFARS 资格的国家则不然？ 鉴于 S32K3 主要面向汽车/工业功能安全应用，有没有人有获得国防相关项目合规性文件的经验？ 我知道社区工程师可能无法直接获取这些信息，所以如果有更好的渠道（例如区域现场应用工程师、代理商合规部门等）可以让我联系，请告诉我。非常感谢您的指导！ 谢谢您！ Re: DFARS Country-of-Origin / Qualifying-Country Compliance for S32K3 Series MCUs 嗨@dbow12 ， 我们没有公开的相关信息。 如需咨询首席运营官相关事宜，请联系[email protected] 。 如有任何出口管制方面的疑问，请联系[email protected]。 不过，我建议您先联系当地的代理商，他们应该能够在这方面为您提供帮助。 此致， 丹尼尔
