无法在 i.MX93 上构建 EASYEVSE Linux 镜像 大家好， 我正在阅读并执行 EVerest 用户指南中的 UG10357 NXP EasyEVSE 电动汽车充电站开发平台。但是，我在运行 bitbake 命令“ bitbake imx-image-everest ”（用户指南第 12 页）时遇到了错误。问题可以在附图的截图中看到。我认为这个问题与 EdgeLock SE05x Plug and Trust 中间件版本有关，该指南基于 04.07.01 版本，但 NXP 只提供 04.08.01 版本。有什么办法解决这个兼容性问题吗？ 谢谢， 罗兰多 评估板 Re: Unable to build EASYEVSE Linux image on i.MX93 嗨@Rolando 请尝试修改此文件，使其与 EdgeLock SE05x 即插即用中间件版本04.08.01相匹配。 Zhiming_Liu_0-1787040520433.png志明_刘_0-1787040520433.png 此致， 志明

Unable to build EASYEVSE Linux image on i.MX93 Hello everyone, I am reading and executing the UG10357 NXP EasyEVSE EV Charging Station Development Platform on EVerest user guide. However I encountered an error when running the bitbake command "bitbake imx-image-everest" (page 12 on the user guide). The problem can be read and seen on the attached screenshot. I believe the issue is related to the EdgeLock SE05x Plug and Trust Middleware version, which the guide is built on version 04.07.01, but NXP only supplies the version 04.08.01. Any idea on how to fix this compatibility problem? Thanks, Rolando Evaluation Board Re: Unable to build EASYEVSE Linux image on i.MX93 Hi @Rolando  Please try to modify this file to match the  EdgeLock SE05x Plug and Trust Middleware version 04.08.01 Zhiming_Liu_0-1787040520433.pngZhiming_Liu_0-1787040520433.png Best Regards, Zhiming

SEMCのRT1176 チップ（外部DRAM）のクロックピンレベルが正常に動作していません。チップのプログラミングは正常に完了しましたが、クロックピンレベルが変化しないことが判明しました。 コアとメモリ 開発委員会 Re: RT1176 of SEMC こんにちは、@qxy111 さん。 NXPのRTシリーズ製品にご関心をお寄せいただきありがとうございます。喜んでお手伝いさせていただきます。 RT1176のSEMC外部ピンは、NVCC_EMC I/O電源ドメインから給電されます。そのため、SEMC_CLKの出力レベルはNVCC_EMCの電源電圧によって決まります。通常、そのハイレベルは、コア電圧である1.1Vではなく、設計で使用されているNVCC_EMC電圧（例えば1.8Vまたは3.3V）と一致させる必要があります。 まず、以下のハードウェアおよびソフトウェア構成をご確認ください。 1. カスタム開発ボードが正常に電源オンになるかどうか、特にNVCC_EMC1 / NVCC_EMC2電源が正しく機能しているかどうかを確認してください。 2：外部SDRAMのVDD電圧はRT1176のNVCC_EMC電圧と一致していますか？ 3：SEMC関連のピンマルチプレクサとSEMCクロックは正しく初期化されていますか？ 4：SDRAMの初期化パラメータは、実際に使用されているSDRAMデバイスと一致していますか？ さらに、SEMC_CLKは高速クロック信号です。この信号が正常かどうかを判断するためにマルチメーターを使用するのではなく、チップのピン付近でオシロスコープを使用して測定することをお勧めします。 MIMXRT1170-EVKB開発ボードの設計図もご参照いただくことをお勧めします。このボードのSDRAMインターフェースは検証済みであり、回路図やソフトウェア構成の比較検証にご利用いただけます。   よろしくお願いします 5月 Re: RT1176 of SEMC コア1.1V信号をNVCC_EMC電圧まで昇圧することはできません。 Re: RT1176 of SEMC コア1.1V信号をNVCC_EMC電圧まで昇圧することはできません。

RVT70HSTNWC00-B (ILI2132A) 和 MIMXRT1176-evkb 您好， 我目前正在使用MIMXRT1176-EVKB进行一个项目。在这个项目中，我希望在RVT70HSTNWC00-B显示屏上显示一些屏幕，并能够注册触摸坐标。 我已经通过NXP论坛上的另一篇文章获得了一个可以正常工作的屏幕： https://community.nxp.com/t5/i-MX-Processors/Creating-a-driver-for-a-MIPI-LCD/mp/1772322 我唯一的问题是，此显示器的触摸驱动程序（ ILI2132A ）与其他驱动程序（例如 GT911）的工作方式略有不同，但仍然使用 I²C 作为协议，而 SDK 中没有使用此驱动程序的示例。 有没有人有基于 MIMXRT1170 系列芯片的解决方案？ 欢迎提供任何帮助和信息。 提前感谢！ 通信与控制（I3C | I2C | SPI | FlexCAN | 以太网 | FlexIO） Re: RVT70HSTNWC00-B (ILI2132A) with MIMXRT1176-evkb 嗨@KobeV ， 我们目前没有为 ILI2132A 提供合适的驱动程序，但 RT1170-EVKB 支持 Zephyr，Zephyr 有一个名为“input_ili2132a.c”的触摸 IC 驱动程序（文档， GitHub ）。 考虑到 ILI2132A 触摸 IC 的具体功能已经在该驱动程序中实现，迁移到裸机驱动程序的过程是完全可以实现的。该驱动程序中使用的所有 GPIO 和 I2C 功能在我们的 SDK 中都应该已经有了对应的底层硬件版本，所以我建议迁移或基于该 SDK 创建您自己的驱动程序。 此外，由于 Zephyr 已经支持 RT1170-EVKB，因此您可以使用基于 Zephyr 的项目进行测试场景，以确保驱动程序的功能，并在任何迁移过程之前调试其功能。 BR， 埃德温。

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。

MCXA185 Reading values of a potentiometer MCXA185 LPADC Potentiometer Reading – Looking for a More Stable ADC Value I am working with an NXP MCXA185 and using the LPADC to read a potentiometer connected to P2_0 / ADC0_A0. My current implementation uses: ADC0 / ADC0_A0 High-resolution conversion mode LPADC hardware averaging of 128 samples Long ADC sample time (kLPADC_SampleTimeADCK19) One ADC reading every 1 ms (1000 Hz) Software-triggered conversions A block average of 100 samples The resulting average is updated every 100 ms So effectively, each value used in the block average has already been averaged by the ADC hardware over 128 conversions. Current approach cmdConfig.conversionResolutionMode = kLPADC_ConversionResolutionHigh; cmdConfig.hardwareAverageMode = kLPADC_HardwareAverageCount128; cmdConfig.sampleChannelMode = kLPADC_SampleChannelSingleEndSideA; cmdConfig.sampleTimeMode = kLPADC_SampleTimeADCK19; Then every 1 ms: 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; } My question Is this a good approach for getting a stable potentiometer value, or is there a better ADC filtering/averaging strategy? In particular, I am wondering about: Is using 128-count hardware averaging + 100-sample software averaging excessive for a potentiometer? Does this actually provide useful additional noise reduction, or am I just increasing the response latency? Would it be better to use a smaller hardware average, such as 16 or 32 samples, and then use a software filter? Would an IIR/exponential moving average be better than a 100-sample block average for a potentiometer because it provides a smoother value while responding faster to knob movement? Is kLPADC_SampleTimeADCK19 appropriate for a typical potentiometer, or should I use a different sample time? Are there any MCXA185-specific LPADC settings that I should enable for better stability? Is polling the ADC result inside a 1 ms function a reasonable implementation, or would a hardware timer trigger + ADC FIFO/interrupt approach be preferable? Pin configuration I am currently using: cfg.pullSelect = kPORT_PullDisable; cfg.driveStrength = kPORT_LowDriveStrength; cfg.passiveFilterEnable = true; cfg.inputBuffer = kPORT_InputBufferDisable; The potentiometer is connected as a voltage divider, with the wiper connected to P2_0 / ADC0_A0. I am mainly interested in getting a value that is: Stable when the potentiometer is not moving Responsive when the potentiometer is turned Not unnecessarily delayed by excessive averaging Resistant to small ADC/wiper noise I would appreciate feedback on whether my current 128 hardware average + 100-sample block average approach is appropriate, and what filtering strategy you would recommend for this application. Analog(ADC|CMP|DAC|OpAmps) MCXA Re: MCXA185 Reading values of a potentiometer Hello, Could you confirm if you are using a high-speed channel? Are you using an example from the SDK as base? You are using a high AVGS value, A higher value of conversions averaged will help you in having a more stable response, but if you are looking for a more balanced response, you can use a smaller AVGS as 16 samples (0100) for providing good noise suppression with much lower conversion time. In MCX-A-185 Datasheet, the Figure 11 and Figure 12 can help you in redirect on how much averaging do you need, considering a High speed mode. For using kLPADC_SampleTimeADCK19 It will depend on your application mission. The shortest sample time maximizes conversion speed for lower impedance inputs. Extending sample time allows higher impedance inputs to be accurately sampled. If you need to optimize conversion speed for a lower impedance as the potentiometer you can use a shorter sample time for example kLPADC_SampleTimeADCK7. If you need to calculate the Required sample time considering the desired accuracy, you can review for the formula in Datasheet Table 33 Subsection 4.B Probably the instructions for ADC Calibration in MCX-A-18 Reference Manual Chapter 45.5.1.2 - 45.5.1.4 are what you are looking for.

i.MX 9は「もう完成形」と言えるのでしょうか？ 数年前にプロジェクトを始めたのですが、NXPの i.MX 9シリーズMPUがリリースされ始めていましたが、ほとんど入手困難だったため、重い i.MX 8 にしました。現段階では、これは私の必要以上の性能なので、もっと小型のMPUに移行したいと考えています。最小の1 i.MX 8を買うつもりでしたが、i.MX91が彼らのCPUの中で最も小さいです。より成熟した8よりも91の方が良いのではないかと考えていました。サーマルが一番気になるので、新品の方が良いと思いますが、まだ新しいので「まだ成熟している」かはわかりません。8に移植されるのがより公平な動きも動機になるかもしれません。 Re: Is i.MX 9 "there yet"? こんにちは、 @ceva156さん あなたのプロジェクトの主な目的は何ですか？現在どのIMX8シリーズ製品を使っていますか? BR Re: Is i.MX 9 "there yet"? こんにちは、 i.MX8のような重いマルチメディアGPU機能は不要です。i.MX91の方がずっと合いやすく、シンプルで低消費電力の設計ができるかもしれません。

FLXIO SENT IP 驱动程序 你好、 我们配置了 4 个 SENT 信道，并分配了附件中所示的信道。我们希望定时器 0、1、2、3 配置为 SENT RX 和 DMA 传输。定时器 5、6、7、8 配置为 SPCO。我们看到带有 SPCO 的 SENT 框架。我们希望定时器比较标志位 0 和 1 置位，并启动 DMA 传输，从而清除该标志。我们使用的是 S32K388 控制器。 仅供参考 - 软件目前只使用 2 个发送通道，即 SPCO 只发送到通道 0 和通道 1。 其中一个现象是 TIMERSDEN 寄存器显示的值为 0x0C。当所有 4 个 SENT 都配置好后，不是应该显示 0x0F 值吗？另外，如果只使用了 2 个 SENT，寄存器中是否应该只显示 2 个设置位？如果只有 2 位，难道不应该是定时/计数器 0 和定时/计数器 1 的 0 位和 1 位吗？我们认为定时器与 TIMERSDEN 寄存器的映射不匹配。 请查看所附屏幕截图，了解配置详情和软件版本如下。 编译版本：S32K3_RTD_6_0_0_D2506_ASR_REL_4_7_REV_0000_0000_20250610 * 项目 ：RTD AUTOSAR 4.7 * Platform ：CORTEXM * Peripheral : FLEXIO_SENT_IP Re: FLXIO SENT IP driver 您好， 我尝试使用 S32DS 中的 Sent_Receiver_S32K344 RTD 示例来模仿您的配置。 我选择 FlexIO 通道 0、1、2、3 配置为 SENT RX 和 DMA 传输，通道 5、6、7、8 配置为 SPC。 调用 Sent_init 后，我看到TIMERSDEN=0xF ，这似乎与通道映射一致。 您能否共享完整配置和简化项目，以便我们直接检查？ BR, Petr Re: FLXIO SENT IP driver 我们使用的是 S32K388 控制器，请查看所附的项目配置文件，并将您的反馈意见告诉我。 Re: FLXIO SENT IP driver 您好， 我不经常使用 EB Tresos，所以我让 SW 团队检查了你们的配置文件。 我已将 SW 工程师的回复（说明回调的使用情况）直接转发给您，忘记放在这里了。如果没有帮助，请告诉我，我可以再问问他们。 谢谢！ 彼得 Re: FLXIO SENT IP driver 您好， 请参见附件中的最新配置。 Re: FLXIO SENT IP driver 你好@annappa 正如我们在电话中讨论的那样，您能否上传最新的配置和代码修改？ 提前感谢！ Re: FLXIO SENT IP driver 谢谢@annappa 另外，您能分享一下您的最新配置吗？ 谢谢您！ Re: FLXIO SENT IP driver 您好， 为通道 0Flexio_Sent_Ip_DmaTimerValue_0_0数组分配的 DMA 缓冲区的值为12。在数据处理过程中，我们计算包括 SPC 在内的数据数（Func：Flexio_Sent_Ip_DmaHandlerline:NumberOfData = Receiver->ChnlCfg[ChannelId].DmaBufferDepth * (Receiver->ChnlCfg[ChannelId].NibbleCnt + 3U + (uint8)((Receiver->ChnlCfg[ChannelId].SpcMode == FALSE) ? 0U : 1U)).0U : 1U)); )生成的缓冲区数组应该是14，而不是12。我们看到 Ch0 的 DMA 缓冲区数值溢出到 Ch1 缓冲区。 下面是附带说明的截图。 DMA_BufferSize12_WithOverFlow：在 DMA 缓冲区大小为 12 时，数据溢出到 Ch1 缓冲区。 DMA_BufferSize14_WithOutOverFlow：DMA 缓冲区大小为 14 时，数据不会溢出到 Ch1。 缓冲区比较代码：在Flexio_Sent_Ip_Cfg.c文件中将缓冲区大小手动编辑为 14 后的代码比较。 谢谢！ Re: FLXIO SENT IP driver 你好@annappa 你能尝试将 SENT Pause 脉冲更改为启用吗？   2026-03-03_11-26-19.png2026-03-03_11-26-19.png 谢谢& ，致以最崇高的敬意。 阿克塞尔 Re: FLXIO SENT IP driver 嗨，Annappa 感谢您的配置更新，我已经向 RTD 团队报告了 DMA 问题，他们正在进一步调查，不过我看到您启用了 FlexIO ISR，但没有启用 DMA ISR。 关于驱动程序的建议是使用 DMA 中的 DMA 中断来处理它。 关于 DMA 缓冲区，我将在收到 RTD 团队的反馈后尽快更新，谢谢！ Re: FLXIO SENT IP driver 此外，我们还需要更新 DMA 缓冲区。 Re: FLXIO SENT IP driver 你好，阿克塞尔、 我们已在 Mcl 中配置了 DMA 逻辑通道和 Flexio 回调函数，请参见所附屏幕截图（DMA_Channel_config），此外，SENT 处理类型已设置为 DMA，请参见所附屏幕截图（SENT_DMA_Process）。 请告诉我驱动程序 如何使用 DMA 中的 DMA 中断来处理？ 此致 安娜帕 Re: FLXIO SENT IP driver 你好，阿克塞尔、 如果我们启用暂停脉冲缓冲区的大小可能会增加，但此配置与我们的传感器配置不匹配，则我们的传感器配置没有暂停脉冲。如果没有暂停，则应生成缓冲区大小为 14 的脉冲阵列。 此致 安娜帕 Re: FLXIO SENT IP driver 你好，Annapa，你试过我几周前发布的暂停复选框吗？ 此外，SENT 的处理是通过通知完成的 Screenshot 2026-03-18 095735.pngScreenshot 2026-03-18 095735.png 请确认启用暂停脉冲可以解决 DMA 缓冲区的问题（它将缓冲区从 12 个元素增加到 14 个元素）。 顺祝商祺！ 阿克塞尔 Re: FLXIO SENT IP driver 您好，Axel, 关于这个问题您有什么最新消息吗？ 这是驱动程序的缺陷吗？ Regards Rahul Re: FLXIO SENT IP driver 你好， 已确认需要更换司机。以下是 Jira 工单： [SRTDCCOM-3401] [已发送]使用 SPC 模式时 Dma 缓冲区溢出 - NXP JIRA 。 此致， 约翰

imx8 nano kernel migration for a53 core from 5.15 to 6.18 imx_rproc_kick Hi  I am upgrading my kernel of the A53 core from 5.15 to 6.18 but i am imx_rproc_kick missing. please find the debug messages # dmesg | grep -nE "rpmsg|virtio|remoteproc|imx-rproc|imx_rproc_kick|goodbye|new channel|get [0-9]" 118:[ 0.030048] imx rpmsg driver is registered. 222:[ 1.538994] remoteproc remoteproc0: imx-rproc is available 224:[ 1.544537] remoteproc remoteproc0: attaching to imx-rproc 225:[ 1.555034] rproc-virtio rproc-virtio.1.auto: assigned reserved memory node vdevbuffer@b8400000 226:[ 1.564322] virtio_rpmsg_bus virtio0: rpmsg host is online 227:[ 1.569846] rproc-virtio rproc-virtio.1.auto: registered virtio0 (type 7) 228:[ 1.576689] remoteproc remoteproc0: remote processor imx-rproc is now attached 327:[ 5.860600] imx-rproc imx8mn-cm7: imx_rproc_kick: failed (1, err:-62) Regards Yadunath R Re: imx8 nano kernel migration for a53 core from 5.15 to 6.18 imx_rproc_kick imx_rproc_kick is not missing in your 6.18 kernel — your log shows the driver reached it and it returned an error: imx-rproc imx8mn-cm7: imx_rproc_kick: failed (1, err:-62) err:-62 means the kick to the remote core timed out. In NXP’s i.MX remoteproc/RPMsg context, this is described as a timeout during the RPMsg kick path; the default BSP remote-ready wait time is 50 ms, and the M-core may need longer if RPMsg initialization is delayed, for example when cache is off or firmware is not ready yet . From your log, the Linux side gets this far: remoteproc0: attaching to imx-rproc rproc-virtio... assigned reserved memory node vdevbuffer@b8400000 virtio_rpmsg_bus virtio0: rpmsg host is online remote processor imx-rproc is now attached So the A53/Linux side is attaching to the already-running M7 and creating the virtio RPMsg host. The failure happens later when Linux tries to notify virtqueue 1 , but the MU/RPMsg side does not complete the handshake in time. The i.MX remoteproc kick path uses the mailbox/MU for IPC interrupt signaling between Linux remoteproc and the hardware MU . Most likely debug areas for your 5.15 → 6.18 upgrade: M7 firmware resource table / RPMsg memory layout Verify the M7 firmware resource table still matches the Linux DT reserved-memory layout. NXP documentation shows the resource table defines the virtio device and vring entries, including RSC_VDEV , NUM_VRINGS , VDEV0_VRING_DA_BASE , VRING_ALIGN , and buffer count. If the image has no valid resource table, NXP’s Linux User’s Guide notes that the resource-table area should be cleared; for i.MX 8M Mini/Nano/Quad LPDDR4 EVK, the documented command is mw 0xb80ff000 0 4 . Device tree reserved-memory and rsc-da Check that the 6.18 DT still reserves the RPMsg vring/buffer/resource-table regions at the same addresses expected by the M7 firmware. Your log shows Linux assigned vdevbuffer@b8400000 , so confirm the M7 firmware’s RPMsg-Lite/OpenAMP config uses the same vring/buffer base region. Also confirm the imx8mn-cm7 node has the correct mboxes , memory-region , and rsc-da values for your board/firmware. M7 firmware readiness The log does not show an RPMsg “new channel” line before the timeout. That suggests Linux is online as RPMsg host, but the M7 side may not be announcing/servicing the channel correctly. Make sure the M7 application initializes RPMsg-Lite/OpenAMP before Linux sends traffic, and that it is not blocked before enabling the endpoint. Firmware built for the new kernel’s RPMsg assumptions NXP has documented cases where the Linux side continues to kick the M7 after the remote RPMsg resources have been destroyed, producing imx_rproc_kick: failed (..., err:-62) . If you are using an SDK ping-pong style demo, confirm whether the M7 firmware exits/destroys the RPMsg endpoint after a fixed number of messages. That pattern can trigger this exact class of error. Suggested next debug commands: dmesg | grep -nE "remoteproc|rproc|rpmsg|virtio|mailbox|mu|imx-rproc|imx_rproc" ls -l /sys/class/remoteproc/remoteproc0/ cat /sys/class/remoteproc/remoteproc0/state cat /sys/class/remoteproc/remoteproc0/name Also compare these between 5.15 and 6.18: grep -n "imx8mn-cm7" -n your-board.dts grep -n "vdevbuffer\|vdev0vring\|rsc\|rpmsg\|reserved-memory" your-board.dts The main thing I would check first is whether the 6.18 device tree still matches the M7 firmware’s resource table and RPMsg memory addresses . Your Linux side is attaching successfully; the failure is at the MU/RPMsg kick/ack stage, which points more to M7 readiness, mailbox/DT configuration, or resource-table/vring mismatch than to the imx_rproc_kick function being absent.

S32K358のLPSPI0とLPSPI2が動作しない こんにちは、NXPヘルパーさん。 RTD:7.0.1 Licunhao_5-1786787375079.pngLicunhao_5-1786787375079.png S32DS3.6.10 Licunhao_3-1786787331998.pngLicunhao_3-1786787331998.png Licunhao_4-1786787354386.pngLicunhao_4-1786787354386.png 私はS32K358 LPSPI0、LPSPI1、LPSPI2を使っていますが、LPSPI1だけが動作し、LPSPI0とLPSPI2は動作しません。ピン配置にいくつか違いがあることに気づきました。 Licunhao_0-1786787130994.pngLicunhao_0-1786787130994.png Licunhao_1-1786787179244.pngLicunhao_1-1786787179244.png マスターには3つのLPSPIを使用します。そして、同期送信APIを使用します。RTD 7.0.1 Licunhao_2-1786787237518.pngLicunhao_2-1786787237518.png しかし、出力はLPSPI1しか出ません。 何か設定する必要はありますか？ どうか助けてください。 Re: S32K358 LPSPI0 and LPSPI2 not work こんにちは、 各SpiExternalDeviceのSpiHwUnit割り当てを再度確認してください。 スクリーンショットから判断すると、SpiExternalDevice_2はCSIB0に割り当てられているようですが、SpiPhyUnitの設定では複数のSPIハードウェアユニットが表示されています。SpiExternalDevice_2が別のLPSPIインスタンスを介して通信することを意図している場合、そのSpiHwUnit参照は、そのインスタンス用に構成された対応するSPIハードウェアユニットを指している必要があります。 SpiExternalDevice_xとSpiPhyUnitのエントリ間のマッピングはユーザーが設定可能なので、番号付けが必ずしも一致する必要はありません。ただし、SpiHwUnitの割り当ては、転送を実行する予定のLPSPIインスタンスと一致していなければなりません。 スクリーンショットから判断すると、SpiExternalDevice_2 は CSIB0 を使用するように設定されているようですが、これは SpiPhyUnit で定義されている最初の SPI ハードウェア ユニットに対応しているものの、その設定は表示されていません。 さらに、3番目のハードウェアユニットはLPSPI_2用に構成されています。LPSPI_2 を介して通信することを意図している場合、SpiExternalDevice_2 は CSIB0 ではなく、その LPSPI インスタンス (CSIB2) に関連付けられた SpiPhyUnit を参照する必要があります。 各SpiExternalDeviceが、希望するLPSPIペリフェラルに関連付けられた正しいSpiPhyUnit(CSIBx)を参照しているか必ず確認してください。誤った割り当てが、転送が1つのSPIインスタンスでのみ観察される理由を説明できるかもしれません。 BR、ペトル

IMX8MP自社設計ボードでシステム起動後にシステムがクラッシュする こんにちは、皆さん i.MX8M Plus(IMX8MP)CPUに 4GB LPDDR4 RAM と 128GB eMMC ストレージを搭載したカスタムボードを設計しました。 以下は起動ログです。ご覧の通り、Linuxを起動した後、コンソールにコマンドを一時的に入力できますが、システムはほぼ即座にフリーズし、完全に反応しなくなります。 この問題は、ログに表示されているEXT4-fsエラーが原因である可能性が高いと考えています。 同じような問題に遭遇した方はいらっしゃいますか?また、トラブルシューティングのアドバイスをいただけませんか?どんなご支援でも大変ありがたく思います！ よろしくお願いいたします。 U-Boot SPL 2020.04 (Aug 10 2026 - 12:59:20 +0800) DDRINFO: start DRAM init DDRINFO: DRAM rate 3200MTS DDRINFO:ddrphy calibration done DDRINFO: ddrmix config done Normal Boot Trying to boot from MMC2 Authentication key not yet programmed keyslot package magic error, do nothing here!

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。

RVT70HSTNWC00-B (ILI2132A) with MIMXRT1176-evkb Hi, I'm currently working on a project with the MIMXRT1176-EVKB. In this project, I would like to display some screens on the RVT70HSTNWC00-B display and be able to register touch coordinates. I already have a working screen thanks to another NXP forum post: https://community.nxp.com/t5/i-MX-Processors/Creating-a-driver-for-a-MIPI-LCD/m-p/1772322 The only issue I have is that the touch driver (ILI2132A) for this display works slightly differently than other drivers (e.g., the GT911) but still uses I²C as protocol and there are no examples in the SDK that use this driver. Does anyone have a solution for this that can be built on the MIMXRT1170 series? All help and information are welcome. Thanks in advance! Communication & Control(I3C | I2C | SPI | FlexCAN | Ethernet | FlexIO) Re: RVT70HSTNWC00-B (ILI2132A) with MIMXRT1176-evkb Hi @KobeV, We do not currently provide a proper driver for the ILI2132A, but the RT1170-EVKB does support Zephyr, which has a driver for this touch IC called "input_ili2132a.c" (Doc, GitHub). Considering that the specifics for the ILI2132A touch IC are already implemented on that driver, the migration process to a bare metal driver is quite achievable. All the GPIO and I2C functions that are using on that driver should already have their bare metal equivalent on our SDK, so I suggest migrating or create your own driver based on that one. Also, since the RT1170-EVKB is already supported by Zephyr, you could do testing scenarios with a Zephyr-based projects to ensure the functionality of the driver and debug its functionality before any migration process. BR, Edwin.

FLXIO SENT IP ドライバー こんにちは、 4 つの SENT チャネルを設定し、添付ファイルに示すようにチャネルを割り当てました。SENT RX および DMA 転送用に Timer0、1、2、3 が構成されることを期待しています。タイマー 5、6、7、8 は SPCO 用に設定されています。SPCO で SENT フレームが表示されています。タイマー比較フラグのビット 0 と 1 が設定され、DMA 転送が開始されてフラグがクリアされることが予想されます。S32K388 コントローラーを使用しています。 参考までに - ソフトウェアは現在 2 つの SENT のみを使用しています。つまり、SPCO はチャネル 0 と 1 に対してのみ送信されます。 1 つの観察結果は、TIMERSDEN レジスタが 0x0C の値を示していることです。4 つの SENT がすべて構成されている場合、0x0F の値が表示されるのではないでしょうか。また、2 つの SENT のみが使用されている場合、このレジスタには 2 つのビット セットのみが表示されるのでしょうか?2 ビットだけなら、ビット 0 と 1 はタイマー 0 ビットとタイマー 1 ビットではないでしょうか?TIMERSDEN レジスタへのタイマー マッピングに不一致があると思われます。 構成の詳細とソフトウェア バージョンについては、添付のスクリーン ショットをご覧ください。 ビルドバージョン: S32K3_RTD_6_0_0_D2506_ASR_REL_4_7_REV_0000_20250610 * プロジェクト: RTD AUTOSAR 4.7 * プラットフォーム: CORTEXM * 周辺機器: FLEXIO_SENT_IP Re: FLXIO SENT IP driver こんにちは、 S32DS 内の Sent_Receiver_S32K344 RTD デモ例を使用して構成を模倣しようとしました。 FlexIO チャネル 0、1、2、3 を SENT RX および DMA 転送用に構成し、チャネル 5、6、7、8 を SPC 用に構成することを選択しました。 Sent_init が呼び出された後、TIMERSDEN=0xF が表示されますが、これはチャネル マッピングと一致しているようです。 直接確認できるように、完全な構成と簡略化されたプロジェクトを共有していただけますか?

RT1176 of SEMC 该芯片的时钟引脚电平（外接DRAM）无法正常工作，正常烧录程序后，检查发现该时钟脚电平未改变 Core and Memory Development Board Re: RT1176 of SEMC Hi @qxy111 ， 感谢您关注恩智浦RT系列产品，很高兴为您服务。 RT1176 的 SEMC 外部引脚由 NVCC_EMC I/O 电源域 供电。因此，SEMC_CLK 的输出电平由 NVCC_EMC 的供电电压决定。正常情况下，其高电平应与设计所采用的 NVCC_EMC 电压一致，例如 1.8 V 或 3.3 V，而不是 1.1 V core 电压。 请首先确认以下硬件和软件配置： 1：您定制开发板是否正常上电，特别是 NVCC_EMC1 / NVCC_EMC2 电源是否正常  2： 外接 SDRAM 的 VDD是否与 RT1176 的 NVCC_EMC 电压匹配  3：SEMC 相关 pin mux、SEMC clock 是否已正确初始化  4： SDRAM 初始化参数是否与实际使用的 SDRAM 器件匹配  另外，SEMC_CLK 是高速时钟信号，建议使用示波器在芯片引脚附近测量，不建议使用万用表判断该信号是否正常。 同时建议您参考 MIMXRT1170-EVKB 开发板设计。该开发板的 SDRAM 接口已经过验证，可以用于原理图和软件配置的对比验证。   Best Regards May Re: RT1176 of SEMC 内核 1.1V 信号无法抬升到 NVCC_EMC 电压 Re: RT1176 of SEMC 内核 1.1V 信号无法抬升到 NVCC_EMC 电压

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！
