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

PN7160A and linux_libnfc-nci on Raspberry Pi 5 2026 64-bit Trixie Hello, I am trying to bring up a PN7160A for a work project and cannot manage to get any attempt of linux_libnfc-nci to work. The patch is obsolete, lgpiod had a overhaul going to version 2. Also have to use flag sudo make install CFLAGS="-Wno-error=implicit-function-declaration" " otherwise I get "demoapp/main.c: In function ‘onMessageReceived’: demoapp/main.c:451:5: error: implicit declaration of function ‘PrintNDEFContent’ [-Wimplicit-function-declaration] 451 | PrintNDEFContent(NULL, NULL, message, length);" I found an old post in 2025 for a PN7150 but when I try to compile I get strange errors such as 'uint8_t' not declared in scope, use . I have the newest Raspberry Pi OS, Trixie Debian 13.6. Looking for some help, thank you. Re: PN7160A and linux_libnfc-nci on Raspberry Pi 5 2026 64-bit Trixie Hello @paulwitulski  Please apply the patch as attachment.

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.

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？

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).

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.

IMXRT1172 LPSPI 带 EDMA 随机间歇 SPI SR = REF 误差 您好， 在使用 LPSPI EDMA 传输 API 时，有时当 SDK 调用我的回调函数（EDMA 完成后）时，如果我查看 LPSPI SR 寄存器，大约每 5-10 次就会有一次 REF 位被设置（读取错误标志/溢出）。我的SPI时钟运行频率为500Khz。我不太确定为什么会出现 SPI RX 溢出，因为 SPI 时钟速度远不够快，不会导致 DMA 跟不上。有什么办法可以排查这个问题吗？还有其他人遇到过这个问题吗？即使出现溢出，数据看起来也总是正确的（我在每次传输之间都将缓冲区清零，所以我知道我看到的不是旧的、过时的数据）。我正在使用传输 API 进行同步发送/接收，并且每 4 毫秒进行一次传输。时间安排上应该不会有问题。 谢谢！ -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 嗨@nxp16 ， 非常感谢您对我们产品的关注以及对我们社区的使用。 SR[REF] 表示接收 FIFO 溢出。如果在传输过程中确实设置了此标志，建议的恢复方法是停止传输，清空 RX FIFO，清除 REF，然后重新开始传输。 然而，在 500 kHz 时，这看起来不像是一个正常的 DMA 带宽问题，假设 RX EDMA 通道在 SPI 时钟开始之前已经准备/启用。由于接收到的数据仍然正确，我建议首先检查 REF 是否为过期标志，或者是否由传输开始/停止序列设置。 如需排除故障，请尝试以下操作： 1. 在开始每次新的转账之前，清除 SR[REF]。 2. 在 TX 开始生成时钟之前，确保 RX DMA 已启用。 3. 检查传输过程中 LPSPI 是否被禁用/重新启用。如果是，请应用相应的勘误解决方法：启用 LPSPI 后清除 REF，或在重新启用 LPSPI 前重置 LPSPI。 希望对你有帮助 顺祝商祺！ 5月 Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 勘误表中提到了两种解决方法：清除 SR 中的位，以及重置外设。遗憾的是，勘误表中关于第一个问题的说法似乎有误，因为 SDK 已经实现了这一点，而且它并不能解决这个问题。遗憾的是，对我来说，重置外设不是一个可行的选择，因为之后我必须重新配置所有内容（它会清除所有寄存器）。目前，我假设如果 DMA 成功完成但出现 REF 错误，那么这是一个假错误，我会忽略它。 谢谢！ -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 嗨@Mike_M3 ， 请检查 LPSPI 在传输过程中是否已禁用并重新启用。如果答案是肯定的，最好避免这种顺序。如果需要禁用/重新启用，请按照文档中记录的解决方法进行操作。 清除 REF 后，请在开始下一次传输之前验证 RX FIFO 状态和接收到的数据，并记录/统计此情况以便进一步调试。 顺祝商祺！ 5月 Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 遗憾的是，SDK 会在传输过程中禁用和启用 LPSPI 外设，而我对此无能为力。 谢谢！ -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 谢谢你的更新。 SDK 可能会在内部禁用/重新启用 LPSPI，但应用程序仍应确保在开始下一次传输之前，之前的 LPSPI 总线传输已完成。 EDMA回调仅指示DMA完成。如果在 SR[MBF] 仍然设置或 SR[TCF] 未设置的情况下，从 EDMA 回调立即开始下一次传输，则 SDK 可能会在 LPSPI 未完全空闲时进入下一次传输设置。 请等待 SR[TCF]=1 或 SR[MBF]=0 后再提交下一次 LPSPI EDMA 传输。

IMXRT1172 LPSPI（EDMA搭載）ランダム断続SPI SR = REFエラー こんにちは、 LPSPI EDMA転送APIを使うとき、SDKからコールバックを呼び出すとき(EDMAが完了したとき)、LPSPI SRレジスタを見ると、約5〜10回の確率でREFビット(エラーフラグ/オーバーフローを読み取る)が設定されています。私のSPIクロックは500kHzで動作しています。SPIクロックはDMAが追いつけなくなるほど速くはないので、なぜSPI RXオーバーフローが発生するのかよくわかりません。この問題を解決する方法はありますか?また、同じ問題を経験した方はいらっしゃいますか?オーバーフローを受け取ってもデータは常に正しく見えます(転送ごとにバッファをゼロにしているので、古い古いデータではないとわかります)。転送APIを使用して同時TX/RXを行い、4msごとに転送を実行しています。タイミングに関しては問題はないはずです。 ありがとうございます -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error こんにちは、 @nxp16 さん。 私たちの製品にご関心を寄せ、コミュニティをご利用いただき、本当にありがとうございます。 SR[REF]は受信FIFOオーバーフローを示します。転送中にこのフラグが実際に設定された場合、推奨される復旧方法は、転送を停止し、RX FIFOを空にし、REFをクリアして、転送を再開することです。 しかし、500 kHzでは、これは通常のDMA帯域幅の問題とは思えません。これは、RX EDMAチャネルがSPIクロック開始前にすでに準備・有効化されていると仮定した場合です。受信データは依然として正しいので、まずREFフラグが古いフラグなのか、それとも転送開始/停止シーケンスによって設定されているのかを確認することをお勧めします。 トラブルシューティングについては、以下をお試しください。 1. 新しい転送を開始する前に、SR[REF]をクリアしてください。 2. TXがクロックの生成を開始する前に、RX DMAが有効になっていることを確認してください。 3. 転送間でLPSPIが無効化/有効化されているかどうかを確認します。無効化/有効化されている場合は、該当するエラータの回避策を適用します。LPSPIを有効にした後でREFをクリアするか、LPSPIを再度有効にする前にリセットします。 お役に立てれば幸いです。 よろしくお願いいたします。 5月 Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 訂正表には2つの回避策が記載されており、SRのビットをクリアすることとペリフェラルをリセットすることだ。残念ながら、最初のエラッタについてはSDKがすでに対応しているため、問題を回避できていないようです。残念ながら、私の場合、ペリフェラルをリセットすることは選択肢にありません。なぜなら、その後すべてを再設定しなければならないからです(すべてのレジスタがクリアされます)。今のところ、DMAが正常に完了したにもかかわらずREFエラーが発生した場合は、それは誤ったエラーであるとみなし、無視することにします。 ありがとうございます -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 残念ながら、SDKは転送間にLPSPI周辺機器を無効化・有効化しており、私はそれをコントロールできません。 ありがとうございます -m Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error こんにちは、@Mike_M3 さん。 転送の合間にLPSPIが無効化され、再度有効化されているかどうかを確認してください。もしそうであれば、この手順を避ける方が望ましい。無効化／有効化が必要な場合は、記載されている回避策に従ってください。 REFをクリアした後、次の転送を開始する前にRX FIFOの状態と受信データを確認し、デバッグのためにこの状態をログに記録/カウントしてください。 よろしくお願いいたします。 5月 Re: IMXRT1172 LPSPI with EDMA random intermittent SPI SR = REF error 最新情報ありがとうございます。 SDKは内部でLPSPIを無効化・再有効化できますが、アプリケーションは次の転送を開始する前に、前回のLPSPIバス転送が完了していることを必ず確認すべきです。 EDMAコールバックは、DMAの完了のみを示します。次の転送が、SR[MBF]が設定されているか、SR[TCF]が設定されていない状態でEDMAコールバックから即座に開始された場合、SDKはLPSPIが完全にアイドルでない状態で次の転送セットアップに入ることがあります。 次のLPSPI EDMA転送を送信する前に、SR[TCF]=1またはSR[MBF]=0になるまでお待ちください。

REF_CLKはENET1_TD2（imx93のU12ピン）を介して供給されます。デバイスツリーでは、この行です。 MX93_PAD_ENET1_TD2__CCM_ENET_QOS_CLOCK_GENERATE_REF_CLK 0x57e オシロスコープで確認したところ、u-boot のクロックは正しいのですが、同様の DMA エラーが発生します (詳細は不明)。 Linuxでは、何かがクロックを止めているのだと思います(私の推測では、DMAエラーがクロックのリリースを引き起こし、Linuxカーネルが未使用として停止しているのだと思います)。 clk_summaryの内容は以下のとおりです。 enable prepare protect duty hardware connection clock count count count rate

Accessing SEMA42 unit on main platform domain from two different cortex M7 in S32K5 I am trying to access SEMA42_1 unit on main platform from two different cortex M7 cores (M7_0 and M7_1) in S32K5. The system hangs up. I cannot share the inhouse workspace here.  The errata ERR053433 states: SEMA42: Simultaneous access to SEMA42_0 and PBRIDGE_2 by more than one application core causes the system to hang. Unfortunately the workaround of using SEMA42_1 does not fix the system hang issue. Can you configure and verify two cortex M-7 cores on S32K56x and have them access gate0 of the SEMA42_1 unit on your Design studio and enable the optimization -Os. The system hang issue goes away by using any ONE of the following, Disable optimisations -O0 Disable Instruction cache Use SRAM of another domain on the SoC e.g. CPE Stepping in via debugger Re: Accessing SEMA42 unit on main platform domain from two different cortex M7 in S32K5 Hello @seasonedbit, As you may know, S32K5 is currently in a preproduction phase; Enablement (documentation, software, and boards) are available for approved customers only, and thus is not supported by our global online support team yet. Could you please contact your FAE or assigned NXP contact who provided the device in the first place? They will be able to provide further support. Thank you for your understanding. Best regards, Julián

在 S32K5 中，从两个不同的 Cortex M7 访问主平台域上的 SEMA42 单元 我正在尝试从 S32K5 中的两个不同的 cortex M7 内核（M7_0 和 M7_1）访问主平台上的 SEMA42_1 单元。系统崩溃了。我无法在此分享内部工作空间。 勘误表 ERR053433 指出：SEMA42：多个应用程序核心同时访问 SEMA42_0 和 PBRIDGE_2会导致系统挂起。 遗憾的是，使用 SEMA42_1 的变通方法并不能解决系统崩溃问题。 您能否在 S32K56x 上配置和验证两个 cortex M-7 内核，并让它们访问 Design studio 中的SEMA42_1单元的 gate0，并启用优化-Os。 使用以下任一方法均可解决系统卡顿问题： 禁用优化 -O0 禁用指令缓存 使用SoC上另一个功能域的SRAM，例如CPE 通过调试器单步执行 Re: Accessing SEMA42 unit on main platform domain from two different cortex M7 in S32K5 你好@seasonedbit ， 如您所知，S32K5 目前处于预生产阶段；启用（文档、软件和板）仅提供给已批准的客户，因此我们的全球在线支持团队尚未提供支持。 请您联系当初提供该设备的现场应用工程师 (FAE) 或指定的恩智浦联系人。他们将能够提供进一步的支持。 感谢您的理解。 此致， 朱利安

Looking for GUI Guider v1.9.0 installer I'm currently working on a project that was originally created with GUI Guider v1.9.0. For compatibility reasons, I need to get the exact v1.9.0 installer, but the official NXP website now only offers newer versions. Does anyone still have the Gui-Guider-Setup-1.9.0 file handy, or know where I can download this specific older version? Also, if I open a v1.9.0 project directly with a newer version (e.g., v1.10.0), will it cause any compatibility issues? Any help or pointers would be greatly appreciated. Thanks! Re: Looking for GUI Guider v1.9.0 installer Hello @李先森 , Thanks for your post. The GUI Guider v1.9.0 installer was not provided any more. However, GUI Guider can upgrade projects created by the last major version and related minor version. Therefore, you can directly use GUI Guider v1.10.x and import project created by GUI Guider v1.9.x. Hope it helps.

寻找 GUI Guider v1.9.0 安装程序 我目前正在开发一个项目，该项目最初是用 GUI Guider v1.9.0 创建的。出于兼容性考虑，我需要获取 v1.9.0 的安装程序，但 NXP 官方网站现在只提供更新的版本。 请问有人手头还有 Gui-Guider-Setup-1.9.0 文件吗？或者知道哪里可以下载这个旧版本？另外，如果我用新版本（例如 v1.10.0）直接打开 v1.9.0 的项目，会不会出现兼容性问题？ 任何帮助或建议都将不胜感激。谢谢！ Re: Looking for GUI Guider v1.9.0 installer 你好@李先森， 感谢您的帖子。GUI Guider v1.9.0 安装程序已不再提供。 但是，GUI Guider 可以升级由上一个主要版本和相关的次要版本创建的项目。因此，您可以直接使用 GUI Guider v1.10.x 并导入由 GUI Guider v1.9.x 创建的项目。 希望对您有所帮助。 BR 塞莱斯特 ----------------------------------------------------------------------------------------------------------------------- 注：如果此帖解答了您的问题，请点击“接受为解决方案”按钮。谢谢你！ -----------------------------------------------------------------------------------------------------------------------

NXP牵引/轴向电机参考固件 你好， 我正在进行一个牵引/轴向控制电机项目，我想了解恩智浦半导体（NXP）用于轴向电机开发的参考软件，这将对我们正在进行的项目的研究和开发非常有帮助。 因此，我请求您提供此问题的解决方案，同时，NXP 提供的牵引/轴向电机参考软件将为我们的研发工作提供可靠的参考。 谢谢 帕万 Re: NXP reference firmware for traction/axial motors 你好， NXP 不提供专门用于轴向磁通电机的专用软件。在大多数情况下，轴向磁通永磁同步电机可以使用与传统径向磁通永磁同步电机相同的永磁同步电机FOC参考软件进行控制。主要的改进在于电机参数化（Rs、Ld、Lq、极对数、磁链等），而控制算法基本保持不变。 典型的切入点是： S32K344 / S32K396 电机控制参考设计 永磁同步电机磁场定向控制（FOC）示例 AMMCLIB 电机控制库 基于模型的设计工具箱示例（如果使用 MATLAB/Simulink） 顺祝商祺！ Peter

NXP reference firmware for traction/axial motors Hello, I am working on a Traction/Axial control motor project and I wanted to know about the reference software for the Axial motor based development from NXP,so it will be very helpful for the reasearch and development of our ongoing project. So I am requesting to provide me the solution for this and also the reference software for Traction/Axial motor from NXP will be a solid reference for our R and D. Thank you Pavan Re: NXP reference firmware for traction/axial motors Hello, NXP does not provide dedicated software specifically for axial-flux motors. In most cases, axial-flux PMSM motors can be controlled using the same PMSM FOC reference software as conventional radial-flux PMSM motors. The main adaptation is the motor parameterization (Rs, Ld, Lq, pole-pair count, flux linkage, etc.), while the control algorithm remains essentially the same. Typical starting points are: S32K344 / S32K396 motor-control reference designs PMSM Field-Oriented Control (FOC) examples AMMCLIB motor-control library Model-Based Design Toolbox examples (if MATLAB/Simulink is used) Best regards, Peter
