KW45B41Z EVK 无法通过板载调试器 MCU Link 进行编程。 你好， 我正在尝试使用kw45b41zevk_hello_world SDK 示例代码对KW45B41Z-EVK进行编程。开始调试时，板载调试器被检测到，但随后出现以下错误： 未检测到可用短波除尘设备。 连接设备后再试一次。 我已将 USB 电缆连接到J14 ，并将JP22 保持开路状态（以便使用板载调试器本身进行编程）。此外，如KW45UM中所述， JP28 引脚 1 和 2 短路了。然而，即使那样，我仍然无法对示例进行编程和调试。 我也尝试过kw45b41zevk_led_blinky SDK 示例，但它的表现也一样。 我还尝试使用外部调试器通过短接JP22来调试电路板，正如KW45UM中所述，但我遇到了同样的问题。 我附上了遇到的问题的截图。 我还尝试使用安全配置工具擦除闪存并写入映像。首先，我短接JP25以启用SW4 ，进入 ISP 模式，然后长按SW4和RESET (SW3) 。测试连接通过后，我成功擦除了闪存（位置0x00000000 ，大小0x100000 ）。然后我使用了以下图片： ${SPT_INSTALL_BIN} \data\sample_data\targets\KW45B41Z8\source_images\kw45b41zevk_led_blinky.s19 我已经成功构建并编程了图像，并且预期的RGB LED1也闪烁，表明 KW45B41Z 微控制器工作正常。然而，即使这样，我仍然无法对电路板进行编程或调试。 Re: KW45B41Z EVK not programming over on board Debugger MCU Link. 你好， @kaif1 你使用的是哪个集成开发环境（IDE）？ MCUXpresso IDE 还是 MCUXpresso for VS Code？ 让我先试一下，然后告诉你默认的跳线设置。 顺祝商祺！ Christine。 Re: KW45B41Z EVK not programming over on board Debugger MCU Link. 你好， @kaif1 请参考我的跳线设置，我在本地验证过，可以成功地将 hello_world 示例烧录到板上。 我使用的是 MCUXpresso IDE，SDK 版本为 25.12.00。 请尝试一下我的跳线设置，然后告诉我是否有效。 顺祝商祺！ Christine。

Linux QBMan QMan 驱动程序 safe_copy_dqrr QorIQ 处理器的 Linux SDK 在驱动程序暂存树中包含qman_high.c 。这包括 safe_copy_dqrr() 函数，注释中说该函数确保读取操作按顺序到达 QBMan ，并且//防止 QBMan 看到 WRAP 事务//。 我推测这里指的是 AXI WRAP 突发事务，而不是与 DQRR 索引回绕有关的任何事情。 谁能解释一下为什么这是一个需要解决的安全问题？ 提前致谢。 QorIQ LS1设备 Re: Linux QBMan QMan driver safe_copy_dqrr 你好， 是的——该评论很可能与总线/缓存线 WRAP 事务有关，而不是与 DQRR 生产者/消费者索引包装有关。 之所以需要“安全”，是因为 DQRR 条目不是普通的 RAM。这是一个 QBMan 门户结构，其内容由 QMan 生成，可能存储在 CPU 缓存中，并由使用VERB 字节中有效位的软件使用。DPAA 手册指出，即使 QMan 以原子方式更新 DQRR 条目，GPP 核心的读取操作也可能无法同时观察到条目的所有字节发生变化；软件必须确保包含有效位的 VERB 字节在加载 DQRR 条目的其余部分之前加载。 所以 safe_copy_dqrr() 试图避免这种不安全的模式： CPU 想要复制 DQRR 条目 编译 器 / CPU / 缓存子系统将其转换为突发或 缓存 行填充。 - > 事务 以 WRAP 样式 读取的方式到达 QBMan - > QBMan / 互连可能 以 与 逻辑字段顺序不同的顺序看到 / 读取节拍。 软件 可能会观察到 与 过期或 尚未 可见 的 条目数据关联的有效 VERB 字节 。 这很重要，因为有效位是同步点。启用 DQRR 条目暂存后，文档特别警告说， DQRR.PI 可以在关联的 DQRR 条目暂存到达处理器缓存之前更新，从而造成竞争；因此，软件应该使用 DQRR 条目中的有效位，而不是 DQRR.PI 来检测生产。有效位本身是一个交替极性位，每次环从最后一个条目回绕到条目 0 时，该位都会翻转。   此致 Re: Linux QBMan QMan driver safe_copy_dqrr 谢谢你的回复。 如果我理解正确，禁用 DQRR 暂存后，CPU 读取 DQRR 条目（在缓存失效和内存屏障之后）会发出触发信号，使缓存行填充，但当 DQRR 条目正在更新时，AXI 回绕突发事务可能会“破坏”这一过程？ 我正在使用 LS1046A RDB，但在 NXP 手册中找不到任何关于这种行为的参考，引用。有相关记录吗？我正在寻找参考，引用来证明这个安全复制功能的合理性。 启用 DQRR 缓存后，QMan 会将 DQRR 条目写入缓存。这个问题是否也存在？ 再次感谢您的帮助。

访问T2081处理器上的MT29F64G08AECAB 与非闪存 您好， 我正在尝试使用T2081 处理器访问MT29F64G08AECAB NAND Flash 。 与非闪存设备的总容量为8 GB，CE1（芯片使能 1）和CE2（芯片使能 2）分别通过CS5和CS6连接到IFC 控制器。 CS5用于连接到CE1 的4 GB 与非闪存。 CS6用于连接到CE2 的4 GB 与非 Flash。 此与非设备的XML闪存配置文件不在以下路径中： {CodeWarrior}\PA\bin\plugins\support\Products\ProductData\FPDevices.mwpdb\FP 因此，我参考文档《 Power Architecture Processors Flash Programmer 应用笔记》（AN4349）创建了一个新的 XML 文件。 我有以下几个问题： 对于 Flash Programmer 配置文件 (.xml)，我应该将 与非 Flash 大小配置为4 GB （每个片选）还是8 GB （CS5 和 CS6 之间的设备总容量）？ 我根据CS5上4 GB容量的 与非 Flash 配置修改了 T2081QDS_init_core.tcl 文件。 运行诊断测试以读取制造商 ID和设备 ID时，我在控制台中遇到以下错误。   我已附上 T2081QDS_init_core.tcl 和 MT29F64G08AECAB.xml 文件供您参考。 请您审核配置，并提供使用T2081 处理器访问 与非 闪存设备的正确步骤？ 此致， 维马尔。 QorIQ T2 设备 Re: Accessing MT29F64G08AECAB NAND Flash on T2081 Processor 你好， 当前超时的最可能原因是： TCL 中的片选索引错误、 IFC 时钟未初始化、 CSOR 页/块几何不匹配、时序过于激进，或者XML 条目指向的算法没有实现正确的 NAND ID 序列。如果您能分享实际的 XML 和修改后的 T2081QDS_init_core.tcl CS5/CS6 部分，我可以直接检查字段和寄存器值。 每个 Flash Programmer 目标/片选使用 4 GB，首先单独启动 CS5，并将 ID 超时作为 IFC 初始化/算法/几何问题进行调试，而不是作为 8 GB XML 大小问题。   此致 Re: Accessing MT29F64G08AECAB NAND Flash on T2081 Processor 你好@Bio_TICFSL ， 谢谢你的回复。 我们尝试使用芯片选择 5 (CS5) 来访问 4 GB 与非闪存，但我们仍然面临之前提到的相同问题。 我已将T2081QDS_init_core.tcl文件和xml文件以文本格式附上，供您参考。 请您查看这些文件和配置值，并提供相应的解决方案？ 此致， 维马尔。 Re: Accessing MT29F64G08AECAB NAND Flash on T2081 Processor 您好，   我尚未收到回复，因此在此跟进我之前的回复。   我对MT29F64G08AECAB 与非 Flash 的时序参数有一些疑问。请参考附件数据表图片中的时序表。 NXP T2081 IFC 接口应该使用哪种与非时序模式？   如何根据这些时序值得出相应的输入时钟周期？   请问如何通过 IFC 从 NxP T2081 处理器访问与非闪存 (MT29F64G08AECAB)？ 此致， 维马尔。

Uart using DMA is not working correct on S32K314 Hello,  We are currently trying to configure LPUART0 channel to work with DMA. The uart channel need to be working at a bitrate of 1Mbps. Our current configuration for UART and DMA looks like this.  The clock is enable in MCU, the buffers are declared inside a non cacheable area , the DMA ISR priority is smaller than the LPUART. Our problem is that we are not able to see the data inside the RX buffer or is incomplete.  Our workflow is like this (similar to LIN communication 😞 prepare rx buffer -> AsyncReceive send the header to the slave -> AsyncSend wait until the data from the slave is received in the next cycle (my function runs in a 1ms task) If I put a break point after AsyncSend is executed I can see all the data send from slave inside the RX buffer. If I let it run there is nothing there or is incomplete. My assumption is that the DMA interrupt comes later.  Could you give us some hints on what is wrong inside our configuration or what I could check next? Thank you! Cosmin Re: Uart using DMA is not working correct on S32K314 Hi@CosminSbera 1.Don't forget to enable DMA Request Option. 2.Don't forget to enable the LPUART0_IRQn interrupt in the "Platform" component. "Platform"->"LPUART0_IRQn --LPUART_UART_IP_0_IRQHandler“

KW45B41Z EVKが搭載デバッガーMCUリンクでプログラムされていないこと。 こんにちは、 kw45b41zevk_hello_world SDKのサンプルコードを使ってKW45B41Z-EVKをプログラムしようとしています。デバッグを開始すると、オンボードデバッガーは検出されますが、その後、次のエラーが発生します。 検出された利用可能なSWDデバイスは0個です。 デバイスを接続して、もう一度お試しください。 USBケーブルは J14 に接続し、 JP22はオン ボードデバッガでプログラムするために開いたままにしています。また、 KW45UMで述べられているように、 JP28のピン1と2は短絡されています。しかし、その後もサンプルプログラムをプログラミングしたりデバッグしたりすることができません。 kw45b41zevk_led_blinky SDKの例も試しましたが、同じように動作します。 KW45UMで説明されているように、外部デバッガを使用してJP22をショートさせてボードのデバッグも試みましたが、同じ問題が発生します。 発生している問題のスクリーンショットを添付しました。 セキュアプロビジョニングツールを使用して、フラッシュメモリを消去してイメージを書き込むことも試しました。まず、 JP25をショートさせてSW4を有効にし、次にSW4とリセット（SW3）を長押ししてISPモードに入りました。接続テストが成功した後、フラッシュメモリ（位置0x00000000 、サイズ0x100000 ）の消去に成功しました。次に、以下の画像を使用しました。 ${SPT_INSTALL_BIN} \data\sample_data\targets\KW45B41Z8\source_images\kw45b41zevk_led_blinky.s19 画像の構築とプログラムは無事にでき、意図した RGB LED1 も点滅しており、KW45B41Z マイクロコントローラが正常に動作していることを示しています。しかし、それでもなお、基板のプログラミングやデバッグができません。 Re: KW45B41Z EVK not programming over on board Debugger MCU Link. こんにちは、 @kaif1 どのIDEを使っていますか? MCUXpresso IDEまたはMCUXpresso for VS Code? 私の方で試してみて、デフォルトのジャンパー設定をお知らせします。 よろしくお願いいたします。 Christine。 Re: KW45B41Z EVK not programming over on board Debugger MCU Link. こんにちは、 @kaif1 ジャンパーの設定を参照してください。ローカル側で確認済みで、hello_world例をボードに正常にフラッシュできます。 そして、MCUXpresso IDEとSDK 25.12.00を使っています。 私のジャンパー設定を試してみて、うまくいくかどうか教えてください。 よろしくお願いいたします。 Christine。

IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error Hi, When using the LPSPI EDMA transfer API, sometimes when my callback is called from the SDK (when EDMA is complete), if I look at the LPSPI SR register, about one in 5-10 times it has the REF bit set (Read error flag / overflow).  My SPI clock is running at 500Khz.  I'm not really sure why I'm  getting this SPI RX overflow as the SPI clock is nowhere near fast enough to cause DMA to not be able to keep up.  Is there any way I can troubleshoot this and has anyone else seen this problem?  The data always looks correct even when I get the overflow (I zero my buffer between each transfer, so I know it's not old stale data I'm looking at).  I'm doing simultaneous TX/RX using the transfer API, and doing the transfer every 4ms.  There shouldn't be any issues with timing. Thanks, -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error Hi @nxp16 , Thank you so much for your interest in our products and for using our community. SR[REF] indicates a receive FIFO overflow. If this flag is really set during a transfer, the recommended recovery is to stop the transfer, empty the RX FIFO, clear REF, and restart the transfer. However, at 500 kHz, this does not look like a normal DMA bandwidth issue, assuming the RX EDMA channel is already prepared/enabled before the SPI clocks start. Since the received data is still correct, I suggest first check whether REF is a stale flag or is being set by the transfer start/stop sequence. For troubleshooting, please try the below: 1. Clear SR[REF] before starting each new transfer. 2. Make sure RX DMA is enabled before TX starts generating clocks. 3. Check whether LPSPI is disabled/re-enabled between transfers. If yes, apply the applicable errata workaround: clear REF after enabling LPSPI, or reset LPSPI before re-enabling. Wish it helps you Best Regards May Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error The errata mentions two workarounds, clearing the bit in SR, and resetting the peripheral.  Unfortunately, the errata seems to be incorrect about the first one as the SDK already does that and it doesn't workaround the problem.  Unfortunately, for me, resetting the peripheral is not an option as I would have to reconfigure everything afterward (it clears ALL registers).  For now, I'm going to assume that if DMA completed successfully and we get a REF error, then it's a false error and I'll just ignore it. Thanks, -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error Unfortunately, the SDK is disabling and enabling the LPSPI peripheral between transfers and I have no control over that. Thanks, -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error Hi @Mike_M3 ,  Please check whether LPSPI is disabled and re-enabled between transfers. If yes, avoiding this sequence would be preferable. If disable/re-enable is required, please follow the documented workaround. After clearing REF, please verify the RX FIFO state and the received data before starting the next transfer, and log/count this condition for further debug. Best Regards, May Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error Thanks for the update. The SDK may disable/re-enable LPSPI internally, but the application should still ensure that the previous LPSPI bus transfer has completed before starting the next transfer. The EDMA callback only indicates DMA completion. If the next transfer is started immediately from the EDMA callback while SR[MBF] is still set or SR[TCF] is not set, the SDK may enter the next transfer setup while LPSPI is not fully idle. Please wait for SR[TCF]=1 or SR[MBF]=0 before submitting the next LPSPI EDMA transfer.

请确认PHY中的复位信号是否正确生效。 当 PHY 在短时间内没有获得时钟信号，并且时钟信号恢复后，必须对 PHY 进行 RESET，以锁存所有配置带，恢复到正常工作模式。 请分享您的完整 dmesg 日志。 顺祝商祺！ Re: DMA Error with imx93 and eqos in RMII 你好， 谢谢你提供的信息。 由于可以访问寄存器，MAC 不会完全保持 RESET 状态。 能否提供原理图连接图，以便确认 REF_CLK 的提供方式？ 另外，请在 `cat /sys/kernel/debug/clk/clk_summary` 文件中分享您的时钟摘要信息。 顺祝商祺！ Re: DMA Error with imx93 and eqos in RMII 关于ref_clk和原理图的回复，请查看另一条消息，我好像不小心按错了回复按钮。 我还尝试了以下方法： https://community.nxp.com/t5/i-MX-Processors/i-MX93-EQoS-RMII-mode-with-internal-50MHz-reference-clock/mp/1947843 ，这看起来很像同一个问题，但也没能成功解决。 感谢您的支持！ Re: DMA Error with imx93 and eqos in RMII 我不想在公共论坛上分享完整的原理图。我可以私下发送吗？ REF_CLK 通过 ENET1_TD2（imx93 的 U12 引脚）提供。在设备树中，就是这一行： MX93_PAD_ENET1_TD2__CCM_ENET_QOS_CLOCK_GENERATE_REF_CLK 0x57e 我们已经用示波器检查过，在 u-启动 下时钟是正确的，但是我们遇到了类似的 DMA 错误（细节较少）。 在 Linux 系统下，某些东西停止了时钟（我猜测是 DMA 错误触发信号，使时钟的版本随后被 Linux 内核停止，因为它未使用）。 以下是 clk_summary 的内容： enable prepare protect duty hardware connection clock count count count rate accuracy phase cycle enable consumer

Getting a Dev Board PCB imported to Altium Our team is working with the S32K148-Q176 Evaluation Board RevB. We are designing a board to interface with the evaluation board and were trying to get a model of it to aid in that endeavor. The files are saved as a BRD when downloaded from your site. We use Altium here and so we cannot import that file. Would your engineering team be able to convert the .BRD to an ASCII .alg file, or another file format that altium can import? Re: Getting a Dev Board PCB imported to Altium Hi @rollypoli  Unfortunately, I do not have a way to convert the Allegro BRD database into Altium format. For similar requests in the past, I have typically recommended using the free Cadence Allegro viewer. Cadence provides a free viewer that can open BRD files and allows you to inspect the PCB database directly. Using the measurement and inspection tools available in the viewer, you should be able to accurately determine the placement and spacing of the connectors, mounting holes, and other mechanical features. This is usually sufficient to reproduce the board outline and connector locations on your own Altium design so that the new PCB remains mechanically compatible with the original board. The free Cadence viewer can be downloaded from: https://www.cadence.com/en_US/home/tools/pcb-design-and-analysis/allegro-downloads-start.html While this is not as convenient as having a native Altium design file, it has worked well for customers who needed to reference an Allegro PCB layout and recreate the relevant mechanical dimensions in another CAD tool. Regards, Lukas Re: Getting a Dev Board PCB imported to Altium Do you have the ability to convert it from a .brd to a .alg (ascII) allegro file? I will look at the viewer Re: Getting a Dev Board PCB imported to Altium I'm sorry but I do not have such possibility. 

GUIGuider 1.10.1 to 2.0.0 migration We have build our GUIGuider projects in version 1.10.1 and I am interested in migrating to the new 2.0.0 version to check out the new features. I found out the old GUIGuider project file could not be loaded in the new version, and I think it is because of the new JSON structure 2.0.0 projects use. Is there an easy way to migrate the projects to the newer version of GUIGuider or do we have to manually convert it? Re: GUIGuider 1.10.1 to 2.0.0 migration Hi @MJHammers_ICP, As you correctly mention, due to the redesigned architecture and new project structure of GUI Guider v2.0.0, this new version of GUI Guider is not fully backward compatible with GUI Guider v1.x. The recommended path would be to recreate the project in GUI Guider v2.0 rather than attempting a file-level conversion. You can find the recommended migration workflow to help you with this task in the following link: Tutorials — GUI Guider Documentation BR, Edwin.

S32K118 FlexIO こんにちは、 FlexIOモジュールをS32K118でモーターホールセンサー信号の両端検出を実装する件について相談したいです。 現在、BLDCモーターからの3つのホールフィードバック信号の立ち上がりエッジと立ち下がりエッジの両方を取得する必要があります。FlexIOピンを入力キャプチャチャネルとして設定しようとしています。しかし、FlexIOで立ち上がりエッジと立ち下がりエッジを同時に検出するように設定する方法がよくわかりません。 デュアルエッジキャプチャのための適切なFlexIOタイマーとシフターの設定ワークフローを共有してもらえますか?それに、割り込みがすべてのエッジでトリガーできるのか、またS32K118 FlexIOをホール信号サンプリングに使う場合に既知の制限や注意点があるのかも知りたいです。どうもありがとうございます。 Re: S32K118 FlexIO こんにちは、 @Niuyanlin さん、 もし**アプリケーション**がBLDCモーターフィードバックのホールセンサーなら、FTMモジュールを検討することをお勧めします。 以下の適用ノートでは、シングルエッジおよびデュアルエッジキャプチャの設定方法とキャプチャ割り込みの生成方法が記載されています:AN5303: S32KにおけるFlexTimerモジュールの機能と動作モード – アプリケーションノート。 「ホールセンサーは独立したFTM(FTM_CHx)のチャンネルに接続されています。FTMはホールセンサー信号の降下エッジと上昇エッジの両方を検出し、キャプチャ割り込みを生成します。" 一方、FlexIOはタイマー減衰モードを通じて間接的に入力キャプチャ動作を構築する必要があり、動作は可能ですが、私の意見ではFTMモジュールの方が適しています。 よろしくお願いします、 ジュリアン Re: S32K118 FlexIO こんにちは、 @Niuyanlin さん、 FlexIOには専用の入力キャプチャ機能がないため、ほとんどのドキュメントは通信エミュレーションに基づいています。私が主に提案できるのは、S32K1のリファレンスマニュアル第54章を参照することです。 シフターやタイマーの設定方法、そしてそれぞれの割り込みについて詳述した以下のアプリケーションノートを参照してください。 AN14284: FlexIOエミュレーテッドインターフェースのタイミングパラメータチューニング |NXPセミコンダクターズ AN12174:FlexIOを用いた通信およびタイミング**ペリフェラル**のエミュレーション – アプリケーションノート FlexIOを理解する FlexIOモジュールは3つのソースから割り込みを生成できます:シフターエラー、シフターステータスフラグ、タイマーステータスフラグです。割り込みを有効にするには、SHIFTSIEN、SHIFTEIEN、TIMIENのビットを設定する必要があります。 しかし、入力キャプチャやBLDCモーター制御のルーチンはありません。ご迷惑をおかけして申し訳ございません。 よろしくお願いします、 ジュリアン Re: S32K118 FlexIO こんにちは、ジュリアンさん。 迅速なご返信と貴重なご提案をいただき、誠にありがとうございました。 FTMがBLDCモーターホールセンサーからのフィードバックとしては優れていることは認識しています。しかし、プロジェクト内のペリフェラルリソースが不足していたため、FlexIOを用いた入力キャプチャ機能を実装せざるを得ませんでした。 FlexIOに関連する詳細なソフトウェア実装計画をご提供していただけると大変ありがたいです。 よろしくお願いします、 牛燕林

iMXEBOOKDC5のタッチコントローラーIC部品番号 チームの皆様へ 私はiMXEBOOKDC5とi.MX8ULP EVKを組み合わせて使用しています。 今のところ、すべて順調に動いています。Eインクディスプレイは正常に動作しており、ボタンとジョイスティックも期待どおりに動作しています。 それでは、ディスプレイのタッチパネルを有効にしたいと思います。しかし、EPDモジュールに使われているタッチコントローラーICの部品番号は特定できません。ICのマーキングがレーザーマーキングで消されているように見えます。 私自身も情報を探してみましたが、見つけることができませんでした。 ぜひ教えていただけますか: iMXEBOOKDC5ディスプレイで使用されるタッチコントローラーのIC部品番号。 タッチ機能をサポートする利用可能なLinuxドライバ、ライブラリ、ソフトウェアパッケージのいずれかです。 ご協力ありがとうございます。 よろしくお願いいたします。 評価ボード Re: Touch Controller IC Part Number for iMXEBOOKDC5 こんにちは、 使用されているタッチコントローラーICはGoodix Technology製のGT911です。 次のリンクでドライバーについてご覧いただけます: https://github.com/nxp-imx/linux-imx/blob/lf-6.18.y/drivers/input/touchscreen/goodix.c よろしくお願いいたします。 Re: Touch Controller IC Part Number for iMXEBOOKDC5 親愛なる、 よろしくお願いいたします。 ちなみに、e-inkパネル用のWayformビンファイルを提供してもらえますか? よろしくお願いいたします。 ライダー

S32K118 FlexIO 您好。 我想咨询一下关于在 S32K118 上使用 FlexIO 模块实现电机霍尔传感器信号的双边沿检测的问题。 目前，我需要捕获来自 BLDC 电机的三个霍尔反馈信号的上升沿和下降沿。我正在尝试将 FlexIO 引脚配置为输入捕获通道。但是，我不太清楚如何设置 FlexIO 以同时检测上升沿和下降沿。 能否分享一下用于双边沿捕获的 FlexIO 定时器和移位器的正确配置流程？此外，我还想知道是否可以在每个边沿触发中断，以及在 S32K118 平台上使用 FlexIO 进行霍尔信号采样时是否存在已知的限制或注意事项。非常感谢。 Re: S32K118 FlexIO 你好@Niuyanlin ， 如果应用场景是无刷直流电机反馈中的霍尔传感器，我建议考虑使用 FTM 模块。 以下应用笔记介绍了如何配置模块以进行单边沿和双边沿捕获，以及如何生成捕获中断： AN5303：S32K 上 FlexTimer 模块的特性和操作模式 – 应用笔记。 “霍尔传感器连接到独立FTM（FTM_CHx）的通道。FTM可以检测霍尔传感器信号的下降沿和上升沿，并生成捕获中断。 ” 相比之下，FlexIO 需要通过定时器递减模式间接构建输入捕获行为，虽然它也能工作，但在我看来，FTM 模块更合适。 此致， 朱利安 Re: S32K118 FlexIO 你好@Niuyanlin ， 由于 FlexIO 没有专门的输入捕获功能，因此大部分文档都是基于通信仿真的。我能给出的主要建议是参考 S32K1 的参考手册第 54 章。 您可以参考以下应用笔记，其中详细介绍了如何配置移位器和定时器以及相应的中断： AN14284：FlexIO 仿真接口的时序参数调优 | 恩智浦半导体 AN12174：使用 FlexIO 模拟通信和定时外设 – 应用笔记 了解 FlexIO FlexIO 模块可以从三个来源产生中断：移位器错误、移位器状态标志和定时器状态标志。要启用中断，您需要设置 SHIFTSIEN、SHIFTEIEN和 TIMIEN 中的相应位。 但是，没有用于输入捕获或 BLDC 电机控制的程序。给您带来的不便，敬请谅解。 此致， 朱利安 Re: S32K118 FlexIO 你好，朱利安。 非常感谢您的及时回复和宝贵建议。 我认识到，对于来自 BLDC 电机霍尔传感器的反馈而言，FTM 是一个更优的选择。然而，由于项目中外围资源不足，我们不得不使用 FlexIO 来实现输入捕获功能。 如果您能提供一份与 FlexIO 相关的详细软件实施方案供我们参考，我们将不胜感激。 此致， 牛艳琳

Accessing MT29F64G08AECAB NAND Flash on T2081 Processor Hi, I am trying to access the MT29F64G08AECAB NAND Flash using the T2081 processor. The NAND Flash device has a total capacity of 8 GB, with CE1 (Chip Enable 1) and CE2 (Chip Enable 2) connected to the IFC controller through CS5 and CS6, respectively. CS5 is used for 4 GB of NAND Flash connected to CE1. CS6 is used for 4 GB of NAND Flash connected to CE2. The XML flash configuration file for this NAND device is not available in the following path: {CodeWarrior}\PA\bin\plugins\support\Products\ProductData\FPDevices.mwpdb\FP Therefore, I created a new XML file by referring to the document Flash Programmer for Power Architecture Processors Application Note (AN4349). I have the following questions: For the Flash Programmer configuration file (.xml), should I configure the NAND Flash size as 4 GB (per chip select) or 8 GB (total device capacity across CS5 and CS6)? I modified the T2081QDS_init_core.tcl file according to the NAND Flash configuration on CS5 with a 4 GB size. When running the diagnostic test to read the Manufacturer ID and Device ID, I encounter following errors in the console.   I have attached the T2081QDS_init_core.tcl and MT29F64G08AECAB.xml files for your reference. Could you please review the configuration and provide the correct procedure to access the NAND Flash device using the T2081 processor? Regards, Vimal. QorIQ T2 Devices Re: Accessing MT29F64G08AECAB NAND Flash on T2081 Processor Hello, The most likely causes of your current timeout are: wrong chip-select index in the TCL , IFC clock not initialized , CSOR page/block geometry mismatch , timing too aggressive , or an XML entry pointing to an algorithm that does not implement the correct NAND ID sequence . If you share the actual XML and the modified T2081QDS_init_core.tcl CS5/CS6 sections, I can check the fields and register values directly. Use 4 GB per Flash Programmer target/chip select, bring up CS5 alone first, and debug the ID timeout as an IFC initialization/algorithm/geometry issue rather than as an 8 GB XML-size issue.   Regards Re: Accessing MT29F64G08AECAB NAND Flash on T2081 Processor Hi @Bio_TICFSL , Thanks for your response, We tried using Chip Select 5 (CS5) to access the 4 GB NAND flash, but we are still facing the same issue that was mentioned previously. I have attached the T2081QDS_init_core.tcl file and the xml file in text format for your reference. Could you please review these files and the configuration values, and provide the appropriate solution? Regards, Vimal. Re: Accessing MT29F64G08AECAB NAND Flash on T2081 Processor Hi,   I am following up on my previous reply, as I have not yet received a response.   I have some doubts regarding the timing parameters of the MT29F64G08AECAB NAND Flash. Please refer to the timing table in the attached datasheet image. Which NAND timing mode should be used with the NXP T2081 IFC interface?   How are the corresponding input clock cycles derived from these timing values?   Can you please give the suggestions to access the NAND Flash (MT29F64G08AECAB) through IFC from the NxP T2081 Processor? Regards, Vimal.

GUIGuider 1.10.1 到 2.0.0 的迁移 我们的 GUIGuider 项目是用 1.10.1 版本构建的，我很有兴趣迁移到新的 2.0.0 版本来体验新功能。我发现旧的 GUIGuider 项目文件无法在新版本中加载，我认为这是因为 2.0.0 项目使用了新的 JSON 结构。 有没有简单的方法可以将项目迁移到新版本的 GUIGuider，还是必须手动转换？

I've taken the imx93-11x11-frdm.dts as base reference, and made the following changes : &iomuxc { pinctrl_eqos: eqosgrp { fsl,pins = < MX93_PAD_ENET1_MDC__ENET_QOS_MDC 0x57e /* OK */ MX93_PAD_ENET1_MDIO__ENET_QOS_MDIO 0x57e /* OK */ MX93_PAD_ENET1_RD0__ENET_QOS_RGMII_RD0 0x57e /* OK */ MX93_PAD_ENET1_RD1__ENET_QOS_RGMII_RD1 0x57e /* OK */ /* MX93_PAD_ENET1_RD2__ENET_QOS_RGMII_RD2 0x57e MX93_PAD_ENET1_RD3__ENET_QOS_RGMII_RD3 0x57e */ MX93_PAD_ENET1_RXC__ENET_QOS_RX_ER 0x51e /* OK */ /* MX93_PAD_ENET1_RXC__CCM_ENET_QOS_CLOCK_GENERATE_RX_CLK 0x51e */ MX93_PAD_ENET1_RX_CTL__ENET_QOS_RGMII_RX_CTL 0x57e /* OK */ MX93_PAD_ENET1_TD0__ENET_QOS_RGMII_TD0 0x57e /* OK */ MX93_PAD_ENET1_TD1__ENET_QOS_RGMII_TD1 0x57e /* OK */ /* refclock for Eth phy */ MX93_PAD_ENET1_TD2__CCM_ENET_QOS_CLOCK_GENERATE_REF_CLK 0x57e /* OK */ /* MX93_PAD_ENET1_TD2__ENET_QOS_RGMII_TD2 0x57e MX93_PAD_ENET1_TD3__ENET_QOS_RGMII_TD3 0x57e */ /* MX93_PAD_ENET1_TXC__CCM_ENET_QOS_CLOCK_GENERATE_TX_CLK 0x5fe */ MX93_PAD_ENET1_TX_CTL__ENET_QOS_RGMII_TX_CTL 0x0000051e /* OK */ /* MX93_PAD_ENET1_TX_CTL__ENET_QOS_RGMII_TX_CTL 0x57e */ >; }; &eqos { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_eqos>; phy-mode = "rmii"; phy-handle = <&ethphy1>; status = "okay"; /delete-property/ assigned-clocks; /delete-property/ assigned-clock-rates; assigned-clocks = <&clk IMX93_CLK_ENET_TIMER2>, <&clk IMX93_CLK_ENET>; assigned-clock-rates = <100000000>, <50000000>; mdio { compatible = "snps,dwmac-mdio"; #address-cells = <1>; #size-cells = <0>; clock-frequency = <5000000>; ethphy1: ethernet-phy@0 { reg = <0>; eee-broken-1000tx; post-power-on-delay-ms = <100>; reset-gpios = <&pcal6524 19 GPIO_ACTIVE_LOW>; reset-assert-us = <15000>; reset-deassert-us = <100000>; }; }; }; Result in uboot is : u-boot=> bootp EQOS_DMA_MODE_SWR stuckFAILED: -110 u-boot=>  Result in linux is : [ 11.484536] imx-dwmac 428a0000.ethernet: Failed to reset the dma [ 11.490536] imx-dwmac 428a0000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed [ 11.499228] imx-dwmac 428a0000.ethernet eth0: __stmmac_open: Hw setup failed I don't understand what i am doing wrong, what i misconifgured, or why the dma does not initialize properly. It's pretty obvious that i'm missing something (a dma error looks like an internal error from the chip, so even if there was an error with the pinmux i don't thihnk i would get this, and i double checked the pinmux). Things i have checked : - clock is correctly sent to the PHY - communication with the PHY on mdio works Any hints on this would be greatly appreciated, Best regards, Julien Re: DMA Error with imx93 and eqos in RMII Reset is set correctly in uboot. I can see the PHY live (the leds work), and communicate with it, but i still get the DMA error. I tried manually disabling and reenabling the PHY via the reset pin in u-boot, but this didn't change anything.

When the PHY is not provided with the clock for a brief period and the clock is enabled back, a reset must be provided to the PHY to latch all the configuration straps, recover into the normal working mode. Please share your entire dmesg. Best regards. Re: DMA Error with imx93 and eqos in RMII Hello, Thank you for the information. Since registers can be accessed, the MAC is not completely held in reset. Could you please share the schematic connections to confirm how REF_CLK is provided? Also, please share your clock summary in cat /sys/kernel/debug/clk/clk_summary Best regards. Re: DMA Error with imx93 and eqos in RMII I don't want to share the full schematics on a public forum. Can i send them privately ? REF_CLK is provided via ENET1_TD2 (pin U12 of imx93). In device tree, this is this line : MX93_PAD_ENET1_TD2__CCM_ENET_QOS_CLOCK_GENERATE_REF_CLK 0x57e We have checked with an oscilloscope that the clock is correct under u-boot, but we encounter a similar dma error (with less details). Under linux, something is stopping the clock (my guess is that the dma error triggers a release of the clock, which is then stopped by linux kernel as unused).

: https://community.nxp.com/t5/i-MX-Processors/i-MX93-EQoS-RMII-mode-with-internal-50MHz-reference-clock/m-p/1947843 which looks a lot like the same issue, but could not get it to work as well. Thanks for your support, Re: DMA Error with imx93 and eqos in RMII I could finally get it to work, using the patch in the link, and the following settings : &eqos { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_eqos>; phy-mode = "rmii"; phy-handle = <&ethphy1>; status = "okay"; assigned-clock-parents = <&clk IMX93_CLK_SYS_PLL_PFD1_DIV2>, <&clk IMX93_CLK_SYS_PLL_PFD0_DIV2>; assigned-clock-rates = <100000000>, <50000000>; enet_clk_sel = <&wakeupmix_gpr 0x2C>; clk_csr = <5>; // snps,rmii_refclk_ext; mdio { compatible = "snps,dwmac-mdio"; #address-cells = <1>; #size-cells = <0>; clock-frequency = <5000000>; ethphy1: ethernet-phy@0 { reg = <0>; eee-broken-1000tx; reset-gpios = <&pcal6524 19 GPIO_ACTIVE_LOW>; reset-assert-us = <15000>; reset-deassert-us = <100000>; smsc,disable-energy-detect; }; }; }; Could you explain me what the patch in  https://community.nxp.com/t5/i-MX-Processors/i-MX93-EQoS-RMII-mode-with-internal-50MHz-reference-clock/m-p/1947843 does, why it is needed? Also, shouldn't these changes be upstreamed, as they look like a regular use case for the soc, nothing exceptional? Re: DMA Error with imx93 and eqos in RMII Hello, Is good to know that is now working. The patch modifies the driver dwmac-imx/EQoS to configure ENET_QOS when RMII is using an external clock. This change is needed because EQoS needs a constant clock during DMA reset. Best regards.

FETMX6ULL-C: Random CTP I2C communication errors when LCD and CTP are connected simultaneously, CTP Hardware platform: FETMX6ULL-C core board.   Capacitive Touch Panel (CTP) GT911 works stably without any I2C errors when only the CTP is connected.   After connecting both LCD display and CTP at the same time, random I2C communication exceptions occur on CTP, which leads to touch function failure occasionally. We suspect that electromagnetic interference introduced by the LCD circuit causes unstable I2C signal of the touch panel.   Related kernel dmesg logs are attached for analysis.   Our software environment: Linux 4.1.15 BSP.   CTP communicates via I2C bus. We have checked hardware wiring and power supply, but the issue still exists.   Looking forward to your technical suggestions.
