COCKPIT_A53 が IMX8 Quad Max に選ばれ、ウォッチドッグがリセットされ続ける もともと Quad Max でアクティブな 6 つのプロセッサすべてに対してウォッチドッグを有効にしていましたが、その後、ATF で COCKPIT_A53 設定を有効にしました。現在、A72 プロセッサが無効になっている場合 (デバイス ツリー レベルではなく SCFW レベル)、ウォッチドッグがトリガーされるようです。 A72 プロセッサに対してのみウォッチドッグを無効にする方法をご存知ですか? i.MX 8ファミリ | i.MX 8QuadMax (8QM) | 8QuadPlus Re: COCKPIT_A53 picked for IMX8 Quad Max, watchdog keeps resetting こんにちは@flobro ! NXP サポートにお問い合わせいただきありがとうございます。 おっしゃる通り、ウォッチドッグによるリセットを防ぐには、SCFW 内でもウォッチドッグを適切に設定する必要があります。 使用している BSP バージョンに基づいて、以下のリンクから SCFW ソース コードをダウンロードできます。 i.MX アプリケーション プロセッサ向け組み込み Linux ダウンロードしたら、パッケージフォルダーにあるバイナリ ファイルを実行して、SCFW のソース コードとドキュメントを抽出します。 よろしくお願いします、 チャビラ

Zephyr support of K27 or K28 Hi, We would like to use Zephyr on the NXP K27 (MK27FN2M0AVMI15) or K28 (MK28FN2M0AVMI15). Is there support for this and/or is there any plan for this support to be added?  Thanks Re: Zephyr support of K27 or K28 Hi @JPH1, As you can see on the following link, the only Kinetis K2x that is supported on Zephyr is the K22: Supported Boards and Shields — Zephyr Project Documentation. Unfortunately, I do not have information whether the K27 or K28 will be supported in the future. BR, Edwin.

S32N55:系统在睡眠后立即被唤醒 你好,团队、 硬件:S32N55-RDB 软件:SW32N5_GRAYVIP_1_0_22_0 FSS 固件:S32N_FSS_FW_R21-11_1.10.0 客户正在 使用配置为前沿检测的 FSS_WKUP2 测试 唤醒功能 。在测试场景中,FSS_WKUP2 仍然处于高位,并且没有出现上升沿。 观察到的行为 即使没有上升沿,系统 在进入睡眠状态后也会 立即 唤醒。 预期行为: 系统 只有在 FSS_WKUP2 上检测到上升沿时 才会唤醒。 下面的波形图详细显示了信号行为。 有趣的是,当我们 将 的 执行顺序 互换 时: 启用唤醒请求 启用上升沿检测 ... 系统的行为符合预期,只有在上升沿才会醒来。 问题 这种行为正确吗? 为什么更改启用唤醒请求和上升沿检测的顺序会影响结果? 感谢您的支持! 谨致问候, Tangsheng FSS_FW 优先权:紧急 资料来源直接客户 Re: S32N55: system is waken up right after sleep 你好,屋大维 感谢你的支持 Re: S32N55: system is waken up right after sleep 也许吧 感谢您分享这些信息。 Re: S32N55: system is waken up right after sleep 已在https://jira.sw.nxp.com/browse/FFSYM-265上修复 Re: S32N55: system is waken up right after sleep 我可以确认,只要序列是 WIREER -> I/WRER,而不是 I/WRER -> WIREER,WISR[3:0]就会被设置为 0xF: 根据我的观察,WIFEER 不会出现这种情况,但我猜这与垫的当前值有关。   Re: S32N55: system is waken up right after sleep 你好,阿琳娜、 是的,以下顺序按预期运行: 1.启用唤醒请求 2.启用上升沿检测 不过,还有一个问题需要考虑:在当前 FSS 固件版本的 Suspend_Ss.c 中,唤醒源 LR_WKPU_FSS_WKUP0-3 被配置为中断。这意味着在发出唤醒请求之前, LR_WKPU_FSS_WKUP0-3 的上升沿检测始终处于启用状态。请在处理问题时考虑到这种情况。 顺祝商祺! 唐生。 Re: S32N55: system is waken up right after sleep 你好,唐生、 客户是否使用 SCMI Scmi_SystemPowerStateSetSynch API 进入 SoC 待机模式? 以下顺序是否可行? 1.启用唤醒请求 2.启用上升沿检测 如果是,则这可能是正确的顺序,正如参考手册所指出的那样: " WIREER 或 WIFEER 配置为在 WRER 之后的上升沿或下降沿,以启用唤醒源 "。 在 FSS 固件中,我们可能会遇到问题,因为我们的顺序对调了:首先配置上升沿/下降沿,然后启用唤醒源。 致以最诚挚的问候, Alina

Server side application to decode NTAG424DNA link generated with non default Master KEY and App KEYS Hi, I am using NTAG424DNA to connect securely to my web application and exchange some information stored into the file data. I used the sdm-backend application https://github.com/nfc-developer/sdm-backend that works fine if the Master key is the default one (with all zeros) but it doesn't work if the Master key or App keys are changed. Is there any available application that can be used to decode the url and returns the UID/counter and file data informations? Thanks, regards Mimmo Authentication server problems Online authentication Re: Server side application to decode NTAG424DNA link generated with non default Master KEY and App Hello @mimmolf Hope you are doing well. I am not fully aware of the functionality that the application you referred offers; however, I can see that, as you pointed out, it does not support personalized authentication Keys. Perhaps you can contact the developer of that repo to see the support they can offer for your setup. Unfortunately, there is no Backend application I could recommend, it should be implemented by the user. Perhaps you could take a look at the Secure Services for the NTAG Product Family | NXP Semiconductors > NTAG Secure Cloud Platform Service; for more information on this service, please try contacting the email address specified in that webpage.

Sync_flagsは、マルチコアコントローラでSMPを使用するときに発生します。 こんにちは、NXP のエンジニアです。s32K324 をデバッグすると、ある問題が発生します。私はfreertos6.0.0とopen SMPを使用していますが、マルチコア コントローラでSMPを使用するとSync_flagsが発生します。 しかし、私はまた書きます   IP_MC_ME->PRTN0_CORE1_ADDR = (uint32)0x00600000; IP_MC_ME->PRTN0_CORE1_PCONF = 0x00000001; IP_MC_ME->PRTN0_CORE1_PUPD = 0x00000001; IP_MC_ME->CTL_KEY = 0x5AF0U; IP_MC_ME->CTL_KEY = 0xA50FU; (IP_MC_ME->PRTN0_CORE1_PUPD == 1) の間 { }; ((IP_MC_ME->PRTN0_CORE1_STAT & MC_ME_PRTN0_CORE1_STAT_CCS_MASK) == 0) の場合 { }; SO、何が問題なのでしょうか? Re: Sync_flags occurs when using SMP in multi-core controllers リリース ノート ファイルに記載されている RTD バージョンを使用することを強くお勧めします。 よろしくお願いいたします。 ルーカス Re: Sync_flags occurs when using SMP in multi-core controllers あなたの方法を試しましたが、まだ sync_flag のままです。質問があります。freertos 11.0 では RTD 6.0 バージョンのみを使用する必要がありますか?私のバージョンはRTD4.0です。 Re: Sync_flags occurs when using SMP in multi-core controllers コードを見ると、コア 1 はブート構成ワード内で有効になっているため、リセット後すぐに起動されることがわかります。 ただし、その後に何らかの遅延ループを使用して、コア 0 のメイン関数でコア 1 を再度有効にしようとしています。 これがあなたの悩みの根本原因ではないでしょうか? Re: Sync_flags occurs when using SMP in multi-core controllers これは私のプロジェクトです。ご覧になっていただけると幸いです。デモではカーネルから起動する方法を使ったのですが、カーネルが正常に起動しなかったように感じます Re: Sync_flags occurs when using SMP in multi-core controllers D_CACHE_ENABLE を無効にしましたが、プログラムはまだそこに留まります。 この問題を解決するためにどのような追加情報が必要か教えてCANますか? Re: Sync_flags occurs when using SMP in multi-core controllers こんにちは@Zyp それは単なるデータキャッシュの問題ではないでしょうか?Freertos パッケージのユーザーマニュアルに従いましたか?以下は 7 ページのスクリーンショットです。 よろしくお願いいたします。 ルーカス

PTN5150A EXT_SEL output not working in non-I2C DFP mode Hello, We have designed some prototype / test boards using PTN5150A to control a USB alternate mode MUX using the EXT_SEL pin. When the PTN5150A is configured as UFP mode by the slide switch, everything works nicely as it should, the output of EXT_SEL changes with cable orientation and the MUX corrects for that. However when configured as DFP mode, EXT_SEL pin does not change with cable orientation, it is always high (LED D3 off). The tests were done by connecting two of these boards together, one configured as UFP and one as DFP. Here is the relevant part of the schematic, the CC and VBUS lines connect directly to the USB-C receptacle, the 3.3V VDD is provided by a LDO connected to VBUS.   Is this intended behaviour? From the datasheet I would have thought that the EXT_SEL output should work at all times, and not be reliant on I2C operation. If not then what could my mistake or issue be?  Thank you Re: PTN5150A EXT_SEL output not working in non-I2C DFP mode Whether use this PTN5150 as DFP connect with others UFP which no included the PTN5150,does this DFP PTN5150 EXT_SEL function good? Re: PTN5150A EXT_SEL output not working in non-I2C DFP mode On the other connected board in UFP mode EXT_SEL correctly indicates cable orientation. I did some further testing and the CON_DET pin is low on the DFP configured board and high on the UFP configured board. So it is not an issue with the EXT_SEL signal itself, instead it seems to me that when connecting two PTN5150A the DFP configured one does not properly detect the connection. Behaviour is the same when switching UFP/DFP roles between the two boards and also with different USB-C to USB-C cables, so I think it is unlikely that this is just a hardware fault on one board and more likely just logic that I do not yet quite understand. Re: PTN5150A EXT_SEL output not working in non-I2C DFP mode Hi When configured as DFP mode, EXT_SEL pin does not change, at this time what about EXT_SEL pin status of UFP?  Re: PTN5150A EXT_SEL output not working in non-I2C DFP mode Yes, same behavior no matter whether the UFP it is connected to is another PTN5150 or just a USB-C "2.0" connector with the appropriate 5.1k pulldowns on CC1/2. It would be nice if someone could either confirm or rule out this being a hardware/silicon bug, maybe using OM13584 PTN5150A-PTN36043 evaluation board.

S32K144 RTD Driver for EB tresos : SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02 : License error I have downloaded "SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02" RTD driver from NXP. But i am unable to use it as I am getting "No license for module ....." for all modules. I checked the plugins folder. The CRYPTOMANIFESTSIG.MF and CRYPTOMANIFEST.MF files are missing in META-INF folder for all modules. Does anyone have a solution for this problem ? Re: S32K144 RTD Driver for EB tresos : SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02 : License error Here is the reply from SW team: After comparation between 3.0.0 QLP02/03 and 3.0.0 version, I saw that: in the 3.0.0 QLP02/03, there are missing files (CRYPTOMANIFEST.MF and CRYPTOMANIFESTSIG.MF) that used to check license. This caused license issues from the customer's side. The dev team also detected this issue, they will provide update packages soon. At the present, there are no workaround and a tentative date. The customer needs to wait for the new packages. Re: S32K144 RTD Driver for EB tresos : SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02 : License error Sorry, let me double-check: The default RTD path is C:\NXP\SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02 The default path for EBTresos is C:\EB\tresos, and the only file in C:\EB\tresos\links is SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02.link In addition, MEM_43_INFLSand MEM_43_EXFLScan also be seen in SW32K1_S32M24x_RTD_R21-11_3.0.0_D2503_ReleaseNotes.pdf, but the Plugin name is not FLS in SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02_D2505_ReleaseNotes.pdf. Do you only want AUTOSAR 4.4 and not AUTOSAR R21-11? Re: S32K144 RTD Driver for EB tresos : SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02 : License error Hi The reinstall does not solve the issue. SW32K1_S32M24x_RTD_R21-11_3.0.0_D2503.exe. does not have FLS module. So, we will not be able to use it. Can we use "SW32K1_S32M24x_RTD_4.4_R21-11_2.0.0_P01" as a temporary solution? What are the differences between these versions - RTD_4.4_R21-11_2.0.0_P01 and RTD_4.4_3.0.0_QLP02_D2505 ? Re: S32K144 RTD Driver for EB tresos : SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02 : License error Hi Sorry for the inconvenience we bring you! If you still receive a license error message when reinstall both EB Tresos and SW32K1_S32M24x_RTD_4.4_3.0.0_QLP02_D2505.exe in the default path, you may have to temporarily install SW32K1_S32M24x_RTD_R21-11_3.0.0_D2503.exe.

MPC5777C FCCU 初始化异常查询 您好, 我目前正在使用带有 MPC5777C 的 FCCU。 初始化 FCCU 时,在 RESET NCFS_CFG [0] 和 NCFS_CFG [1] 之后,如果我将 NCFS_CFG [2] 初始化为 0x0000,则会出现异常。我检查了 NCFS_CFG[2],发现其中包含与 ECC 相关的寄存器。异常可能是在初始化这些寄存器时产生的吗? 我想知道在初始化过程中出现异常是否正常。 Re: MPC5777C FCCU Initialization Exception Inquiry 你好 嗯,我觉得 FCCU 的代码本身没有问题。 您是逐步调试代码,还是在 FCCU 配置上运行代码。 由于 FCCU 配置模式受配置看门狗的保护,如果尝试调试配置代码,就会出现超时。但这样也不会放弃 IVOR1。 如果看到 IVOR1,则检查 MSCR 寄存器中异常的详细信息 我没有看到这个问题与 FCCU 有关,而是与某些访问限制有关。 找出 IVOR1 的原因,你就知道该去哪里找了。 顺祝商祺! Peter Re: MPC5777C FCCU Initialization Exception Inquiry 初始化代码没有什么特别之处。FCCU 根据参考代码进行初始化,如下所示。出现异常的部分会在注释中注明。 FCCU.TRANS_LOCK.R = 0xBCU; FCCU.CTRLK.R = 0x913756AFU FCCU.CTRL.R = 0x1U; FCCU.NCF_E[0].R = 0xFFFFFFFFU; FCCU.NCF_E[1].R = 0x7FFFU; FCCU.NCFS_CFG[0].R = 0x0000U; FCCU.NCFS_CFG[1].R = 0x0000U; FCCU.NCFS_CFG[2].R = 0x0000U; // 异常 IVOR1 发生!!!! FCCU.CTRLK.R = 0x825A132BU FCCU.CTRL.R = 0x2U; Re: MPC5777C FCCU Initialization Exception Inquiry 你好 如果我将 NCFS_CFG[2] 初始化为 0x0000,就会出现异常。 我不熟悉你的配置,但要配置故障时的RESET反应。因此,您的异常情况与这一更改无关。 您收到的是哪种异常?IVORxx 编号? 我想知道在初始化过程中出现异常是否正常。 例外从来不是正常状态。这意味着您在访问等方面存在一些问题... 有关详细信息,请参阅核心参考手册: 7.8 例外确认和优先事项 顺祝商祺!

Please verify that this configuration matches your hardware setup to avoid potential issues. Re: s32k312 clock error i using the external clock or the FIRC.. But I don't know much about hardware, so I can't tell if the clock is from outside or if I use fifc. Where can I find this? ldo? this picture is my setting.. it's normal set Re: s32k312 clock error Hi @LEEYM  Are you using the external clock or the FIRC as the source for SCS_CLK? Also, are you working with a custom board or an evaluation board (EVB)? If you are using a custom board with an external clock, please ensure that the configuration matches the actual clock frequency on your hardware. If you are using an EVB, could you please share your configuration settings? That way, I can replicate the setup on my side. BR, VaneB

如何使用 Embedded Artists 2EL M.2 模块 A3 上的外置天线端口? 我有一个 i.MX91 评估板。它配备了 M.2 WiFi 板。如果连接天线,增益没有变化。 我想知道如何为这个板设置 ANTCFG,以及如何激活 M.2 板上的外部天线端口。我该怎么做? 另外,根据"iw mlan0 link" ,RX 速度从 6mBits/S 到 228mBits/S 不等,这正常吗? Re: How can I use the external antenna ports on Embedded Artists 2EL M.2 Module A3? 您好, 感谢您对恩智浦半导体产品的关注, 根据EA的文档,你应该重新设计板,重新放置电阻器。 https://www.embeddedartists.com/wp-content/uploads/2022/05/2EL_M2_Datasheet.pdf 此致

Image Artifacts in 12MP Capture with i.MX8MP GStreamer Pipeline Hello, I'm developing a Qt application for the i.MX8MP targeting a 12MP image capture device and encountering image artifacts in the captured PNG images. Hardware/Software Environment: SoC: NXP i.MX8MP Camera: 12MP sensor via MIPI CSI-2 (CSI1) Framework: Qt with GStreamer Capture resolution: 4048x3040 GStreamer Pipeline:     c descr = g_strdup_printf("v4l2src name=video_source " "device=/dev/video-isp-csi1 " "io-mode=dmabuf ! " "video/x-raw, width=4048,height=3040 ! tee name=t " "t. ! queue max-size-buffers=1 leaky=downstream ! imxvideoconvert_g2d " "name=g2d rotation=3 ! video/x-raw, width=480, height=800 ! appsink " "name=app_sink_live max-buffers=1 drop=True " "t. ! queue ! appsink name=app_sink_snapshot max-buffers=1 drop=True"); Issue: The captured PNG images frequently contain visual artifacts (see attached image). The artifacts appear as corrupted regions or visual distortions in the final image. Observations: MIPI CSI debug logs indicate the CSI signal appears to be stable and correct The issue occurs intermittently but frequently enough to be problematic Both the live preview path (with rotation and scaling) and snapshot path are affected Questions: Could this be a buffer synchronization issue between the ISP and the downstream elements? Are there recommended buffer settings or pipeline configurations for high-resolution capture on i.MX8MP? Could the dmabuf io-mode be causing memory coherency issues? Are there any known issues with the ISP driver at this resolution? Any guidance would be greatly appreciated! Image:   i.MX8ULP Multimedia Re: Image Artifacts in 12MP Capture with i.MX8MP GStreamer Pipeline Hi, Thank you for taking your time. I could finally solve the problem. FYI: I am stick to DMA in this case because its 12MP and image buffers are to big for user space manipulations. No image artifacts are seen anymore After adding clean stop (GST_STATE_NULL) in bool GstVideoPipeline::stop() and after we wait for state change to complete to ensure ISP device is closed: ret = gst_element_get_state(m_pimpl->pipeline, &state, &pending, GST_CLOCK_TIME_NONE); now the Gstreamer pipeline stop is as follows: bool GstVideoPipeline::stop() { if (!VideoPipeline::stop()) { return false; } GstStateChangeReturn ret = gst_element_set_state(m_pimpl->pipeline, GST_STATE_NULL); if (ret == GST_STATE_CHANGE_FAILURE) { qCritical() << "Failed to change pipeline state to NULL"; return false; } // Wait for state change to complete to ensure ISP device is closed // this is key to image artifact issue GstState state, pending; ret = gst_element_get_state(m_pimpl->pipeline, &state, &pending, GST_CLOCK_TIME_NONE); if (ret == GST_STATE_CHANGE_FAILURE) { qCritical() << "Failed to wait for NULL state"; return false; } // Release references to child elements so they can be properly freed if (m_pimpl->g2d != nullptr) { gst_object_unref(m_pimpl->g2d); m_pimpl->g2d = nullptr; } if (m_pimpl->appSinkLive != nullptr) { gst_object_unref(m_pimpl->appSinkLive); m_pimpl->appSinkLive = nullptr; } if (m_pimpl->appSinkSnapshot != nullptr) { gst_object_unref(m_pimpl->appSinkSnapshot); m_pimpl->appSinkSnapshot = nullptr; } qDebug() << "Pipeline stopped and all resources freed"; return true; } Re: Image Artifacts in 12MP Capture with i.MX8MP GStreamer Pipeline Hello. What sensor model is being used? are you using a custom ISP tuning file (XML)?.   There are know issues with debayering and ISP configuration if  sensor-specific tuning or profile is not properly adapted (image quality may degrade over time) >Could this be a buffer synchronization issue between the ISP and the downstream elements?>Are there recommended buffer settings or pipeline configurations for high-resolution capture on i.MX8MP? In your pipeline, max-size-buffers=1 limits the queue to hold only one buffer, If the downstream element is slow (encoding or saving) the buffer may be dropped Can you try increasing buffer sizes + leaky=no to prevent buffer drops: max-size-buffers=4 leaky=no Could you also try to use use filesink instead of appsink to debug image output independently of Qt >Could the dmabuf io-mode be causing memory coherency issues? Can you test your pipeline using io-mode=mmap and io-mode=auto  to discart dmabuf issues >Are there any known issues with the ISP driver at this resolution? 8MP ISP supports up to 4096x3072,  where width must be divisible by 16 and height by 8 due to macroblock alignment for dewarp and ISP processing.  Your resolution of 4048x3046 is valid Regards
