Licensing and open-source status for MR-VMU-TROPIC GitHub repository Hello,   I am having a look at the MR-VMU-TROPIC FMU base board. The documentation on GitBook explicitly states: "They are both opensource designs and may be copied and recreated as you wish."   However, the official GitHub repository currently lacks a LICENSE file, despite being described as an "Open-Source FMU base board" also there, which makes it difficult to use or adapt the design files safely.   I noticed there have been recent updates in the repository. Could the team add a standard open-source license file (such as the BSD-3-Clause license used on the TropicCommunityVMU) to the GitHub repository?   Thank you!   Re: Licensing and open-source status for MR-VMU-TROPIC GitHub repository Thank you for highlighting that issue. I will adress that internally. Re: Licensing and open-source status for MR-VMU-TROPIC GitHub repository A license file has been added to the github repo GitHub - NXP-Robotics/MR-VMU-TROPIC: Preview of TROPIC VMU single board RT106X · GitHub https://github.com/NXP-Robotics/MR-VMU-TROPIC/blob/main/LICENSE Thanx again for highlighting that!

I.MX95 LVDS clock output can not be changed Hello everyone, Q1: I am working on single port LVDS display in the kernel lf-6.12y. I added my own panel config in driver/gpu/drm/panel/panel-simple.c, but the clock always be around 150Mhz when I was measuring the clock pins. But the other signals were working. But, In the lf-6.18y, the clock can output correctly, and in dual-port mode clock changing is also ok in the both versions. Is it a known problem or my mistake. Because some reasons I hope I can solve this problem in lf-6.12y.  The following are my settings panel-simple.c: static const struct display_timing lt9211_test_timing = { .pixelclock = { 35916000, 35916000, 35916000 }, .hactive = { 280, 280, 280 }, .hfront_porch = { 40, 40, 40, }, .hback_porch = { 60, 60, 60 }, .hsync_len = { 30, 30, 30 }, .vactive = { 1424, 1424, 1424 }, .vfront_porch = { 15, 15, 15 }, .vback_porch = { 17, 17, 17}, .vsync_len = { 4, 4, 4 }, .flags = DISPLAY_FLAGS_DE_HIGH, }; static const struct panel_desc lt9211_test = { .timings = &lt9211_test_timing, .bpc = 8, .num_timings = 1, .size = { .width = 292, .height = 111, }, .bus_format = MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA, .bus_flags = DRM_BUS_FLAG_DE_HIGH, .connector_type = DRM_MODE_CONNECTOR_LVDS, }; my lvds config in the device-tree &{/}{     lvds1_panel {         //compatible = "3ascreen,sa123hwv-l51";        compatible = "lt9211_test";        backlight = <&lvds_backlight>;        status = "okay";        port {            panel_in: endpoint {                remote-endpoint = <&lvds1_out>;            };        };     }; Q2: Under some conditions, the LVDS common voltage will not be aligned between the data lanes and clock in the same hardware. Or some signal missing like LVDS1 D3P has signal but D3N doesn't. Do you have ideas why this happened? Could some programs cause this? Q3: Is any config can shift the LVDS clock phase. Thanks Re: I.MX95 LVDS clock output can not be changed Q1: It is likely a known lf-6.12y LVDS clock driver limitation/bug , not your panel-simple.c timing mistake. In single-port LVDS the driver/clock path is likely forcing or rounding to about 148.5/150 MHz . Since lf-6.18y works, the practical fix is to backport the LVDS/LDB clock changes from lf-6.18y to lf-6.12y , or patch the 6.12y LVDS driver/PLL clock table to allow your 35.916 MHz pixel clock. git diff lf-6.12.y..lf-6.18.y -- \ drivers/gpu/drm/bridge/imx/imx95-ldb.c drivers/phy/freescale/phy-fsl-imx8mp-lvds.c drivers/clk/imx/clk-imx95-blk-ctl.c \ arch/arm64/boot/dts/freescale/imx95.dtsi \ arch/arm64/boot/dts/freescale/imx95-*-lvds* Q2: If one LVDS pair side is missing, like D3P has signal but D3N has no signal , that is usually not caused by panel timing . Check: LVDS channel enablement: LVDS0/LVDS1 mismatch fsl,data-width / fsl,data-mapping PHY enablement connector or PCB open/short soldering issue termination/probing method possible damaged LVDS output pin Software can cause wrong channel/lane/data-width setup, but one side of a differential pair missing strongly suggests hardware, pad, routing, termination, or measurement issue . Q3: For i.MX8MP LVDS, there is no normal device-tree config to shift LVDS clock phase . Fix clock frequency/timing/PHY setup instead. Re: I.MX95 LVDS clock output can not be changed Thank you so much. The lvds patch is so helpful.

SAI padding bits configuration on imx93 I'm having a hard time correctly configuring the sai link between the imx and the codec under linux. The codec is an AK4619, used in 4 channels TDM mode. Playback is ok at 48KHz / 32 bits TDM mode, MSB first and MSB justified. For capture, the AK4619 only supports 24 bits. The data is MSB justified, which means that non significant bits comes after the relevant bits (significative bits are 8-31). On the other side, the sai sets the FBT to 23, which means that the significative bits are 0-23. I tried to find the relevant settings, but could not. I understand that FBT tells where the relevant data starts, but i can't find which register sets the data size (which, in my case, is 24, as opposed to the word size which is 32). What register needs to be set, or what config must be set in the device tree ? Here's the relevant config i actually use : &sai3 { #sound-dai-cells = <0>; clocks = <&clk IMX93_CLK_SAI3_IPG>, <&clk IMX93_CLK_DUMMY>, <&clk IMX93_CLK_SAI3_GATE>, <&clk IMX93_CLK_DUMMY>, <&clk IMX93_CLK_DUMMY>, <&clk IMX93_CLK_AUDIO_PLL>; clock-names = "bus", "mclk0", "mclk1", "mclk2", "mclk3", "pll8k"; assigned-clocks = <&clk IMX93_CLK_SAI3>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_sai3>; assigned-clock-parents = <&clk IMX93_CLK_AUDIO_PLL>; assigned-clock-rates = <24576000>; fsl,sai-mclk-direction-output; fsl,sai-asynchronous; status = "okay"; }; simple-audio-card,dai-link { link-name = "AK-4CHANNELS"; format = "i2s"; dai-tdm-slot-num = <4>; dai-tdm-slot-width = <32>; fsl,mclk-equal-bclk; cpu { sound-dai = <&sai3>; dai-tdm-slot-num = <4>; dai-tdm-slot-width = <32>; assigned-clocks = <&clk IMX93_CLK_SAI3>; }; codec { sound-dai = <&ak4619>; system-clock-frequency = <24576000>; assigned-clocks = <&clk IMX93_CLK_SAI3>; dai-tdm-slot-num = <4>; dai-tdm-slot-width = <32>; }; }; I've checked with a scope, and the data on the sai line looks correct. Any hints on this would be really appreciated. Re: SAI padding bits configuration on imx93 Thanks. The problem is that i don't know what to write in this register. The only doc i can find is julienblanc_0-1789720432684.pngjulienblanc_0-1789720432684.png I've highlighted the relevant line in my case. So yes, i should write 0b11111 in FBT, but how do i tell that only 24 bits are relevant ? My understanding is that i cannot use W0W and WNW as they tell the word size, which in my case is 32 bits. In can't find anything relevant in neither of the RCRx registers. Regards, Julien Re: SAI padding bits configuration on imx93 Hello, Did you try to use -f S32_LE with ALSA during recording/playback? This configuration is not done in device tree, if you want to configure it from the driver, you need to modify register TCR5/RCR5 here: https://github.com/nxp-imx/linux-imx/blob/b096ce610e956cc2596006343df8a2a26ed6e019/sound/soc/fsl/fsl_sai.h https://github.com/nxp-imx/linux-imx/blob/b096ce610e956cc2596006343df8a2a26ed6e019/sound/soc/fsl/fsl_sai.c Best regards. Re: SAI padding bits configuration on imx93 Actually, it seems that the extra bits do not cause any issue. I could get audio to work correctly after altering the driver to write the correct value in FBT. Best regards,

MRF13750H AWR 型号 你好， 我正在尝试使用贵公司网站上提供的官方设计文件，将 MRF13750H 晶体管模型导入 Cadence AWR Microwave Office。 下载完设计套件和晶体管模型后，尝试打开模型时出现错误。我已附上错误信息的截图。 Luis_V_0-1789581238483.pngLuis_V_0-1789581238483.pngLuis_V_0-1789581238483.png 我已经联系了Cadence的技术支持。他们的团队也尝试下载并打开该模型，并确认遇到了完全相同的问题。 请您核实这些文件，并告知我如何解决这个问题？ 最好的， 路易斯·V. 射频 Re: MRF13750H AWR MODEL 你好 Luis_V 再会！ 该错误是由于兼容性问题导致的。您尝试安装的模型比较老旧，是为早期版本的 AWR 设计环境设计的。目前尚无计划对其进行更新以适应新版本的软件。 如果您需要使用此型号，最实用的解决方案是安装一个较旧版本的 AWR，例如 2015 年左右的版本（例如 AWR v11 或 v12），该版本与此型号兼容。这样应该可以避免遇到 GetIAwrUserIO DLL 错误。 对于可能由此导致的不便，我们深感抱歉。 希望这些信息对您有所帮助，如果您还需要其他帮助，请告诉我。 祝你今天过得愉快，一切顺利。 Re: MRF13750H AWR MODEL 你好，拉法， 我正在联系 Cadence 公司，看看他们是否可以提供旧版本的 AWR。与此同时，您能否帮我联系一下设计 MRF13750H-915MHz 板的工程师，或者其他可以帮我收集一些数据的人？我这里有NXP的这款产品，我们需要用它。 此外，您之前提到过您可以在您那边打开 ADS/AWR 来查看 T 型接头不连续性、斜接弯头、开路效应等。您能否给我发送一个窗口截图，以便我检查微带线的尺寸和特性？在等待 Cadence 的回复期间，如果您能运行负载牵引分析来找出源阻抗和负载阻抗值，我将不胜感激。 最好的， 路易斯·维拉纽瓦 Re: MRF13750H AWR MODEL 你好 Luis_V 再会！ 由于 NXP 已决定（暂时）缩减射频领域的业务，我们该部门的许多同事已经离开了公司，这意味着可用的人员减少了。所以，请告诉我您有什么问题，我会尽力解答；如果我无法解答，我会将此事上报给客户经理寻求支持，但我不能与您分享任何人的联系方式。 感谢您的理解。 祝你今天过得愉快，一切顺利。

imx93 上的 SAI 填充位配置 我在 Linux 系统下配置 imx 和编解码器之间的 sai 连接时遇到了困难。 编解码器为 AK4619，采用 4 通道 TDM 模式。48KHz / 32 位 TDM 模式下播放正常，MSB 优先且 MSB 对齐。 对于捕获，AK4619 仅支持 24 位。数据采用最高有效位对齐，这意味着非有效位位于相关位之后（有效位为 8-31）。另一方面，sai 将 FBT 设置为 23，这意味着有效位为 0-23。 我尝试查找相关设置，但没有找到。我知道 FBT 指示相关数据的起始位置，但我找不到哪个寄存器设置数据大小（在我的情况下是 24，而不是字长 32）。 需要设置哪个寄存器，或者需要在设备树中设置哪些配置？以下是我实际使用的相关配置： &sai3 { #sound-dai-cells = <0>; clocks = <&clk IMX93_CLK_SAI3_IPG>, <&clk IMX93_CLK_DUMMY>, <&clk IMX93_CLK_SAI3_GATE>, <&clk IMX93_CLK_DUMMY>, <&clk IMX93_CLK_DUMMY>, <&clk IMX93_CLK_AUDIO_PLL>; clock-names = "bus", "mclk0", "mclk1", "mclk2", "mclk3", "pll8k"; assigned-clocks = <&clk IMX93_CLK_SAI3>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_sai3>; assigned-clock-parents = <&clk IMX93_CLK_AUDIO_PLL>; assigned-clock-rates = <24576000>; fsl,sai-mclk-direction-output; fsl,sai-asynchronous; status = "okay"; }; simple-audio-card,dai-link { link-name = "AK-4CHANNELS"; format = "i2s"; dai-tdm-slot-num = <4>; dai-tdm-slot-width = <32>; fsl,mclk-equal-bclk; cpu { sound-dai = <&sai3>; dai-tdm-slot-num = <4>; dai-tdm-slot-width = <32>; assigned-clocks = <&clk IMX93_CLK_SAI3>; }; codec { sound-dai = <&ak4619>; system-clock-frequency = <24576000>; assigned-clocks = <&clk IMX93_CLK_SAI3>; dai-tdm-slot-num = <4>; dai-tdm-slot-width = <32>; }; }; 我用示波器检查过了，sai 线上的数据看起来是正确的。 任何提示都将不胜感激。 Re: SAI padding bits configuration on imx93 谢谢。 问题是我不知道该在这个登记簿里写些什么。我能找到的唯一一份文件是 julienblanc_0-1789720432684.pngjulienblanc_0-1789720432684.png 我已将我案例中的相关行高亮显示。所以，是的，我应该在 FBT 中写入 0b11111，但我如何知道只有 24 位是相关的呢？我的理解是，我不能使用 W0W 和 WNW，因为它们表示字长，而我的字长是 32 位。我在两个 RCRx 寄存器中都找不到任何相关信息。 此致， 朱利安 Re: SAI padding bits configuration on imx93 你好， 您在录制/播放时是否尝试过使用 ALSA 的 -f S32_LE 参数？ 此配置并非在设备树中完成，如果要通过驱动程序进行配置，则需要在此处修改寄存器 TCR5/RCR5： https://github.com/nxp-imx/linux-imx/blob/b096ce610e956cc2596006343df8a2a26ed6e019/sound/soc/fsl/fsl_sai.h https://github.com/nxp-imx/linux-imx/blob/b096ce610e956cc2596006343df8a2a26ed6e019/sound/soc/fsl/fsl_sai.c 顺祝商祺！ Re: SAI padding bits configuration on imx93 实际上，这些额外的部分似乎并没有造成任何问题。修改驱动程序，将正确的值写入 FBT 后，音频就能正常工作了。 顺祝商祺！

NXP i.MX93 EVKのNPU温度と使用率を取得する方法 私はi.MX93 EVKを使っており、Ethos-UのNPU温度と稼働率(負荷)を実行時に監視したいのですが、このデータをどうやって取得できますか? 目的は、AIモデルの推論中にハードウェアパラメータを監視することです。 i.MX8MPlusで以下のパラメータを監視できます。i.MX93でも同様のことを実現したいです。 8Mプラス RAM=$(free -m | awk '/Mem:/ {print $3}') CPU_LOAD=$(vmstat 1 2 | tail -1 | awk '{print 100 - $15}') CPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp 2>/dev/null || echo "N/A") GPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone1/temp 2>/dev/null || echo "${CPU_TEMP}") GPU_LOAD=$(cat /sys/kernel/debug/gc/load 2>/dev/null | awk '/load/ {gsub("%","",$3); if (max=="" || $3>max) max=$3} END {if (max!="") print max "%"; else print "N/A"}') i.MX93 RAM=$(free -m | awk '/Mem:/ {print $3}') CPU_LOAD=$(vmstat 1 2 | tail -1 | awk '{print 100 - $15}') CPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp) i.MX93 NPU(ethos-u)のGPU_LOADとGPU_TEMPをどうやって監視できますか? Linux Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK こんにちは、@sonal-acldigital i.MX 8M Plusも i.MX 93も、NPU温度をリアルタイムで監視する方法を提供していません。 - imx8MP、thermal_zone0はCPUの温度を表し、thermal_zone1はSoCの温度を表します。 - imx93、thermal_zone0はCPUの温度を表します。 - NPU、 nputopのようなツールは存在しません。 パフォーマンスチューニングに関する情報については、セクション7.1.2を参照してください。「ハードウェアアクセラレータのプロファイリング」、 MLユーザーガイドに収録。 B.R Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK @pengyong_zhang i.MX 8M Plusとi.MX 93の熱ゾーンについてご説明いただきありがとうございます。以下の点を明確にしていただけますか? i.MX8MPLUS 1. GPU温度: 個別のGPU温度を読み取る専用のシステムパス(/sys/class/thermal/thermal/thermal_zoneX/temp)はありますか?それともソックサーマルゾーン(thermal_zone1)だけでカバーされているのでしょうか? 2. GPU負荷: /sys/kernel/debug/gc/loadを読み込むことがGPU負荷の確認の標準的な方法ですか?それともMLユーザーガイドのセクション7.1.2に詳述されている手順も必要ですか? i.MX93: NPUの負荷と温度を監視するネイティブツール（nputopなど）がないため、次の点について質問させてください。推論の実行をNPUにオフロードした場合とCPUのみで実行した場合のCPU負荷の減少を測定することで、相対的なNPU使用率を導き出すことは妥当でしょうか？ もしこの方法が推奨されていない場合、推論実行中のNPU活動を推定するために使える代替のドライバーノードやパフォーマンスカウンターはありますか? Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK こんにちは、@sonal-acldigital 返信が遅くなり申し訳ありません。最近、ひどいウイルス性の風邪にかかり、しばらくの間高熱が続きました。今日やっと熱が下がった。 1.GPU温度を読み取る専用の経路はありません。 2. はい、/sys/kernel/debug/gc/loadによるGPU負荷監視が現在の方法です。 IMX93： NPU使用率は、プロファイリングを用いてご自身で計算する必要があります。 B.R

I.MX95 LVDS 时钟输出无法更改 大家好， 问题1： 我正在内核 lf-6.12y 中开发单端口 LVDS 显示功能。我在 driver/gpu/drm/panel/panel-simple.c 中添加了自己的面板配置，但是当我测量时钟引脚时，时钟频率始终在 150Mhz 左右。但其他信号都正常。 但是，在 lf-6.18y 中，时钟可以正确输出，并且在双端口模式下，两个版本的时钟切换也都可以。这是已知问题还是我的操作失误？由于某些原因，我希望能在lf-6.12y版本中解决这个问题。 以下是我的设置 panel-simple.c： static const struct display_timing lt9211_test_timing = { 像素时钟= { 35916000, 35916000, 35916000 }, .hactive= { 280, 280, 280 }, .hfront_porch= { 40, 40, 40, }, .hback_porch= { 60, 60, 60 }, .hsync_len= { 30, 30, 30 }, .vactive= { 1424, 1424, 1424 }, .vfront_porch= { 15, 15, 15 }, .vback_porch= { 17, 17, 17}, .vsync_len= { 4, 4, 4 }, .flags= DISPLAY_FLAGS_DE_HIGH， }; static const struct panel_desc lt9211_test = { 时间= &lt9211_test_timing， .bpc= 8， .num_timings= 1， 。尺寸= { 。宽度= 292， 。高度= 111， }, .bus_format= MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA， .bus_flags= DRM_BUS_FLAG_DE_HIGH， .连接器类型= DRM_MODE_CONNECTOR_LVDS， }; 设备树中的 lvds 配置 &{/}{ lvds1_panel { //兼容 = "3ascreen,sa123hwv-l51"; 兼容 = "lt9211_test"; 背光 = <&lvds_backlight>; 状态 = "正常"; 港口 { panel_in: 端点 { 远程端点 = <&lvds1_out>; }; }; }; Q2： 在某些情况下，同一硬件中的数据通道和时钟之间的 LVDS 公共电压将无法对齐。或者某些信号缺失，例如 LVDS1 D3P 有信号但 D3N 没有信号。你知道这是为什么吗？某些程序会导致这种情况吗？ Q3： 是否有任何配置可以改变LVDS时钟相位？ 谢谢！ Re: I.MX95 LVDS clock output can not be changed 问题1：这很可能是LF-6.12Y LVDS时钟驱动程序的一个已知限制/错误，而不是你的panel-simple.c文件的问题。时机把握失误。在单端口LVDS中，驱动/时钟路径很可能强制或四舍五入到大约148.5/150。MHz。由于 lf-6.18y 可以正常工作，实际的解决方法是将 lf-6.18y 的 LVDS/LDB 时钟更改向后移植到 lf-6.12y，或者修补 6.12y LVDS 驱动程序/PLL 时钟表，以允许使用您的 35.916 MHz 像素时钟。 git diff lf-6.12.y..lf-6.18.y -- \ drivers/gpu/drm/bridge/imx/imx95-ldb.c drivers/phy/freescale/phy-fsl-imx8mp-lvds.c drivers/clk/imx/clk-imx95-blk-ctl.c \ arch/arm64/boot/dts/freescale/imx95.dtsi \ arch/arm64/boot/dts/freescale/imx95-*-lvds* Q2：如果 LVDS 对中的一侧缺失，例如 D3P 有信号但 D3N 没有信号，这通常不是面板时序造成的。查看： LVDS通道启用：LVDS0/LVDS1不匹配 fsl，数据宽度 / fsl，数据映射 PHY 使能 连接器或PCB开路/短路 焊接问题 终止/探测方法 LVDS 输出引脚可能损坏 软件可能会导致错误的通道/线路/数据宽度设置，但差分对的一侧缺失强烈表明存在硬件、焊盘、布线、端接或测量问题。 Q3：对于 i.MX8MP LVDS，没有常规的设备树配置来改变 LVDS 时钟相位。改为修复时钟频率/时序/PHY设置。 Re: I.MX95 LVDS clock output can not be changed 太感谢了。 lvds补丁太有用了。

MRF13750H AWR MODEL Hello, I am trying to import the MRF13750H transistor model into Cadence AWR Microwave Office using the official design files provided on your website. After downloading both the design kit and the transistor model an error is generated when attempting to open the model. I have attached a screenshot of the error message. Luis_V_0-1789581238483.pngLuis_V_0-1789581238483.pngLuis_V_0-1789581238483.png I have already contacted technical support at cadence. Their team attempted to download and open the model as well, and they confirmed that they encountered the exact same issue. Could you please verify these files and let me know how to resolve this? Best, Luis V. RF Re: MRF13750H AWR MODEL Hello Luis_V Good day! The error is due to compatibility issues. The model you are trying to install is quite old and was designed for earlier versions of AWR Design Environment. Currently, there are no plans to update it for newer versions of the software. If you need to use this model, the most practical solution is to install an older version of AWR, such as one from around 2015 (for example, AWR v11 or v12), which is compatible with this model. This should allow you to work without encountering the GetIAwrUserIO DLL error. We apologize for any inconvenience this may cause. I hope this information has helped you, please let me know if you need help with anything else. Have a great day and best of luck. Re: MRF13750H AWR MODEL Hello Rafa, I am reaching out to Cadence to see if they can provide an older version of AWR. In the meantime, could you connect me with the engineer who designed the MRF13750H-915MHz Board or someone who can help me gather some numbers? I have this product from NXP and we need to use it. Additionally, you mentioned earlier that you could open ADS/AWR on your end to view the tee-discontinuities, mitered bends, open-end effects, etc. Would you be able to send me a screenshot of the window so I can check the microstrip dimensions and characteristics? I would also appreciate if you could run a load-pull analysis to find the source and load impedance values while I wait on Cadence. Best, Luis Villanueva Re: MRF13750H AWR MODEL Hello Luis_V Good day! Since NXP has decided to ramp down operations in the RF area (for the moment), many of our colleagues from that department have left the company, meaning there are fewer people available. So, please let me know what questions you have, and I will try to answer them; if I can't, I will escalate the matter to get support from an AE, though I cannot share anyone's contact details with you. Thanks for your understanding. Have a great day and best of luck.

How to get NPU Temperature and utilization for NXP i.MX93 EVK I am using i.MX93 EVK and want to monitor the Ethos-U NPU temperature & utilization(load) at runtime how can I get this data ? The agenda is to monitor the HW-parameters during the inference of AI-models. I could monitor the below parameters using i.MX8MPlus I want to achieve the similar for i.MX93. 8MPlus RAM=$(free -m | awk '/Mem:/ {print $3}') CPU_LOAD=$(vmstat 1 2 | tail -1 | awk '{print 100 - $15}') CPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp 2>/dev/null || echo "N/A") GPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone1/temp 2>/dev/null || echo "${CPU_TEMP}") GPU_LOAD=$(cat /sys/kernel/debug/gc/load 2>/dev/null | awk '/load/ {gsub("%","",$3); if (max=="" || $3>max) max=$3} END {if (max!="") print max "%"; else print "N/A"}') I.mx93 RAM=$(free -m | awk '/Mem:/ {print $3}') CPU_LOAD=$(vmstat 1 2 | tail -1 | awk '{print 100 - $15}') CPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp) How can I monitor the GPU_LOAD & GPU_TEMP for i.MX93 npu(ethos-u) ? Linux Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK Hi @sonal-acldigital  Neither the i.MX 8M Plus nor the i.MX 93 offers a method to monitor NPU temperature in real time. - imx8MP, thermal_zone0 represents the cpu-thermal temperature ，thermal_zone1 represents the soc-thermal temperature. - imx93, thermal_zone0 represents the cpu-thermal temperature. - NPU, There is no such tool like nputop. For information on performance tuning, please refer to Section 7.1.2, "Profiling for Hardware Accelerators," in the ML User Guide. B.R Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK @pengyong_zhang Thanks for clarifying the thermal zones for the i.MX 8M Plus and i.MX 93. Could you please clarify the following: i.MX8MPLUS 1. GPU Temperature: Is there a dedicated system path (like /sys/class/thermal/thermal_zoneX/temp) to read individual GPU temperatures, or is it covered solely under the soc-thermal zone (thermal_zone1)? 2. GPU Load: Is reading /sys/kernel/debug/gc/load the standard method for checking GPU load, or is the process detailed in Section 7.1.2 of the ML User Guide required for this as well? i.MX93: Since there is no native tool (like nputop) to monitor NPU load and temperature, we would like to ask: Is it valid to derive relative NPU utilization by measuring the reduction in CPU load when offloading inference execution to the NPU vs. running on the CPU alone? If this method isn't recommended, is there any alternative driver node or performance counter we can use to estimate NPU activity during an inference run? Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK Hi @sonal-acldigital  Sorry for the late reply. I recently had a severe viral cold and had a high fever for a while. The fever just broke today. 1. There is no dedicated path to read the GPU temperature. 2. Yes, GPU load monitoring via /sys/kernel/debug/gc/load is the current method. IMX93： You need to calculate the NPU utilization yourself using profiling. B.R

如何获取 NXP i.MX93 EVK 的 NPU 温度和利用率 我正在使用 i.MX93 EVK，想要监控 Ethos-U NPU 在运行时的温度和利用率（负载），请问如何获取这些数据？ 本次议程旨在监测人工智能模型推理过程中的硬件参数。 我可以使用 i.MX8MPlus 监测以下参数，我想在 i.MX93 中实现类似的功能。 8MPlus RAM=$(free -m | awk '/Mem:/ {print $3}') CPU_LOAD=$(vmstat 1 2 | tail -1 | awk '{print 100 - $15}') CPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp 2>/dev/null || echo "N/A") GPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone1/temp 2>/dev/null || echo "${CPU_TEMP}") GPU_LOAD=$(cat /sys/kernel/debug/gc/load 2>/dev/null | awk '/load/ {gsub("%", "$3"); if (max== || $3>max) max=$3} END {if (max!=) print max "%"; else print "N/A"}') i.MX 93 RAM=$(free -m | awk '/Mem:/ {print $3}') CPU_LOAD=$(vmstat 1 2 | tail -1 | awk '{print 100 - $15}') CPU_TEMP=$(awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp) 如何监测 i.MX93 npu(ethos-u) 的 GPU_LOAD 和 GPU_TEMP？ Linux Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK 你好@sonal-acldigital i.MX 8M Plus 和 i.MX 93 都没有提供实时监测 NPU 温度的方法。 - imx8MP，thermal_zone0 表示 CPU 温度，thermal_zone1 表示 SoC 温度。 - imx93，thermal_zone0 表示 CPU 温度。 - NPU，没有像 nputop 这样的工具。 有关性能调优的信息，请参阅第 7.1.2 节。《机器学习用户指南》中的“硬件加速器性能分析”。 B.R Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK @pengyong_zhang感谢您澄清 i.MX 8M Plus 和 i.MX 93 的热区划分。请您澄清以下问题： i.MX8MPLUS 1. GPU 温度：是否有专门的系统路径（如 /sys/class/thermal/thermal_zoneX/temp）来读取单个 GPU 温度，还是仅包含在 soc-thermal 区域（thermal_zone1）中？ 2. GPU 负载：读取 /sys/kernel/debug/gc/load 是检查 GPU 负载的标准方法吗？还是也需要按照 ML 用户指南第 7.1.2 节中详述的过程进行检查？ i.MX93： 由于没有像 nputop 这样的原生工具来监测 NPU 负载和温度，我们想问：将推理执行卸载到 NPU 与单独在 CPU 上运行相比，通过测量 CPU 负载的减少量来推导出相对 NPU 利用率是否有效？ 如果这种方法不推荐，是否有其他驱动节点或性能计数器可以用来估算推理运行期间的 NPU 活动？ Re: How to get NPU Temperature and utilization for NXP i.MX93 EVK 你好@sonal-acldigital 抱歉回复晚了。我前段时间得了重感冒，还持续高烧了一段时间。今天刚退烧。 1.没有专用的路径来读取GPU温度。 2. 是的，目前通过 /sys/kernel/debug/gc/load 进行 GPU 负载监控的方法就是如此。 IMX93： 您需要使用性能分析自行计算 NPU 利用率。 B.R
