i.MX95: EdgeLock Enclave Key Import Error - SAB CMD [0x47] Resp [0x1829] (Invalid Signature) Hi Team, We are currently working on importing a private key to an i.MX95 device following the guidelines in application note AN14898. Environment & References: Target Device: i.MX95 Demo Application: imx_sec_apps/imx-ele-apps SPSDK Version: Latest standard toolset Activities Completed So Far: Installed Python, pip, and the SPSDK toolset. Successfully built both the Host and Device applications. Copied device/bin/ele_key_import and device/scripts/run_test_on_board.sh to our target i.MX95 hardware. Executed the device-side flow to generate nxp_prod_ka_puk.bin. Transferred nxp_prod_ka_puk.bin back to our host environment. Generated SRK keys (secp384r1) using the SPSDK utility according to the SPSDK Documentation since we do not have final production keys yet. Generated the signed_msg.bin on the host side using the standard key import template (with the -k parameter set to secp384r1). Transferred the generated signed_msg.bin to the i.MX95 hardware. Command used to generate signed message: nxpimage signed-msg export -c key_exchange_temp.yaml -w assets Attached key_exchange_temp.yaml for reference. When running run_test_on_board.sh on the i.MX95 target device, all files are found, but the EdgeLock Enclave rejects the signature on the signed message block.Here is our target terminal log: nxp_prod_ka_puk.bin exists. oem_public_key.pem exists. signed_msg.bin exists.

Request for Reference Documentation: Integrating Ai tools with Cody Chat in S32DS Dear NXP Community Team, I am currently working with S32 Design Studio and using the Cody Chat feature available in the IDE. I would like to know whether it is possible to integrate external AI models such as OpenAI ChatGPT and Anthropic Claude into the Cody Chat section of S32 Design Studio. My requirement is to use an AI assistant directly inside S32DS for activities such as: C/C++ code generation and explanation Embedded C development Debugging compiler and linker errors CAN, SPI, I2C, UART and ADC development S32K3/S32K344 development Understanding and working with the current S32DS project context I found that the official Sourcegraph Cody documentation describes support for both OpenAI and Anthropic models, including model configuration and Bring Your Own Key (BYOK) options. Could you please clarify: Is the Cody integration used in S32 Design Studio capable of connecting to external AI providers such as ChatGPT/OpenAI and Claude? Can we configure our own API key for these AI providers in the Cody Chat section? Is there any official NXP documentation, S32DS documentation, Cody documentation, or example project explaining how to configure or integrate external AI models with Cody in S32DS? If this functionality is not directly supported in the current S32DS version, is there an official method to extend the Cody/Eclipse plugin to support external AI providers? Are there any restrictions in the S32DS implementation of Cody compared with the standard Sourcegraph Cody implementation? For reference, I found the following Sourcegraph documentation regarding supported LLMs and model configuration: Supported LLMs Cody Model Configuration Cody Model Configuration Examples Could you please provide the appropriate NXP reference documentation or recommended procedure for implementing this in S32DS? Thank you for your support. Best regards, Aravind Togaralli

MIPI-DSI on an iMX95 no clock output Software summary ------------------------------------------------------------ Bootloader: U-Boot Kernel version: 6.6.138-7.6.1-devel #1 SMP PREEMPT Fri May 8 12:46:27 UTC 2026 Kernel command line: root=PARTUUID=74fae1d2-02 ro rootwait console=tty1 console=ttyLP0,115200 Distro name: NAME="TDX Wayland with XWayland Upstream" Distro version: VERSION_ID=7.6.1-devel-20260728203137-build.0 Distro variant: - Hostname: bmr-verdin-imx95-08828817 ------------------------------------------------------------ Hardware info ------------------------------------------------------------ HW model: Toradex Verdin iMX95 WB on Verdin Development Board Toradex version: 0089 V1.0C Serial number: 08828817 Processor arch: aarch64 ------------------------------------------------------------ We have a custom carrier board with the Toradex Verdin iMX95. We are running the Toradex multimedia image with customizations (the base device tree is imx95-verdin-wifi-dev.dts). We have a custom display from YES Optoelectronics (7” 1024x600) that is a MIPI-DSI 4 lane interface. I used the device tree and driver model from the raydium rm67191 as the starting point. I am able to get the power supply timing correct on startup and the backlight comes on and the BIST works (there is a pin on the display that can be pulled high for BIST), so I believe the display is working. All four data lanes show single-ended activity but the CLK lines are at 0 volts. At power up the CLK lines start at around 200mV and then they go to 1.2 volts for a little bit but then they go to 0 volts and they stay at 0 volts. I know the verdin SoM works because I can get the RVT70HSDNWCA0 display to work on a Mallow carrier board. The driver goes through probe → add panel → get modes → prepare → enable. Am I forgetting to turn on or configure a clock somewhere maybe? What does it mean when the CLK signals (both P and N) are at 0 volts? My overlay looks like /dts-v1/; /plugin/; &mipi_dsi { status = "okay"; panel@0 { compatible = "yes,ytc700tlbd"; reg = <0>; reset-gpios = <&gpio2 17 1>;//GPIO_ACTIVE_HIGH>; power-supply = <&reg_vcc_disp_dvdd>; backlight = <&lvds_backlight>; dsi-lanes = <4>; port@0 { reg = <0>; panel1_in: endpoint { remote-endpoint = <&mipi1_panel_out>; }; }; }; ports { /delete-node/ port@1; port@1 { reg = <1>; mipi1_panel_out: endpoint { remote-endpoint = <&panel1_in>; }; }; }; }; &displaymix_irqsteer { status = "okay"; }; &dpu { assigned-clocks = <&scmi_clk 80>, //IMX95_CLK_DISP1PIX>, <&scmi_clk 18>, //IMX95_CLK_VIDEOPLL1_VCO>, <&scmi_clk 19>; //IMX95_CLK_VIDEOPLL1>; assigned-clock-parents = <&scmi_clk 19>; //IMX95_CLK_VIDEOPLL1>; assigned-clock-rates = <0>, <3360000000>, <420000000>; status = "okay"; }; &pixel_interleaver { #address-cells = <1>; #size-cells = <0>; status = "okay"; channel@0 { reg = <0>; status = "okay"; }; }; &display_pixel_link { status = "okay"; }; Can someone confirm they were able to get a MIPI-DSI display to work with the iMX95?

SJA1105S+TJA1120A+RTL8211FI RTL8211FIはMDIO/MDCを通じてPHYアドレスを取得し、通常通りインターネットにアクセスできますが、両TJA1120AはMDIO/MDC経由でPHYアドレスを取得したり、通常インターネットにアクセスしたりすることはできません。その理由は?調整や変更が必要なハードウェアはありますか? 1. NXP i.MX95 SOCを使用して、3つのネットワークカードPHY(1つのRTL8211FIと2つのTJA1120A)を外部に接続します。ここで、2つのTJA1120AはSJA1105Sを介して外部拡張されます。 2. リソースの割り当て: (1)NXP i.MX95のENET1をRTL8211FIに割り当てます(PHYアドレスは001です)。 (2)NXP i.MX95のENET2をSJA1105Sに割り当て、SJA1105SのRGMII1を最初のTJA1120A(PHYアドレス002)に割り当て、SJA1105SのRGMII2を2番目のTJA1120A(PHYアドレス004)に割り当てます。 3. 回路図についてはPDFファイルを参照してください。 Re: SJA1105S+TJA1120A+RTL8211FI こんにちは、 @leven さん。 回路図のレビューから、TJA1120Aデバイスに接続されたMDIO/MDCインターフェースの電圧レベルが問題の一つと考えられます。   TJA1120A VDDIOは1.8Vドメインに接続されているようです。したがって、TJA1120Aに接続されたMDIOおよびMDC信号もこの1.8 V I/Oドメインと互換性があるはずです。   しかし、回路図では、TJA1120AデバイスへのMDIO/MDC信号はU20レベルトランスレータを経由してルーティングされているように見える。ENET1_MDIO_BUF/ENET1_MDC_BUF側はTJA1120Aデバイスに向かって接続されており、レベルシフターの3.3V側にあるようです。これは不一致を引き起こします。なぜなら、TJA1120AのMDIO/MDCピンは1.8VのVDDIOドメインを基準としているからです。   これが、RTL8211FIには正しくアクセスできる一方で、TJA1120AデバイスはMDIO上で検出できない理由かもしれません。RTL8211FIのMDIO/MDC接続は1.8V側にあるようで、これは設定されているI/O電圧と一致しています。   TJA1120AのMDIOおよびMDCの電圧レベルをオシロスコープで直接確認してください。もし3.3Vで駆動され、TJA1120A VDDIOが1.8Vの場合、ハードウェア接続を調整して、MDIO/MDC信号がTJA1120A VDDIOと同じ電圧領域を使用するようにする必要があります。 よろしくお願いいたします。 パベル

使用 1.8V 输出的外部振荡器驱动 RT117x 驱动 RTC_XTALI 是否可以使用1.8V直流电平的外部时钟驱动RTC_XTALI? 因为确保外部时钟与 VDD_SNVS_ANA 匹配会增加设计的复杂性。此外,1.8V 也低于时钟输入的绝对最大额定值。 Re: RT117x Driving RTC_XTALI using External oscillator with 1.8V output 嗨@Marwan , 如 MIMXRT1160/1170 处理器的硬件开发指南中所述,如果要将外部低频时钟馈送到 RTC_XTALI,则 RTC_XTALO 引脚必须保持未连接状态,或者由互补信号驱动。该强制时钟的逻辑电平不得超过 VDD_SNVS_DIG 电平。 此外,i.MX RT1170 交叉处理器数据手册指出,VDD_SNVS_DIG 的工作电压范围为 0.81 V 至 0.95 V,典型值为 0.85 V。 这意味着 1.8 V 的信号将超过 VDD_SNVS_DIG 电压等级。 最良好的问候, 巴勃罗

RT117x Driving RTC_XTALI using External oscillator with 1.8V output Is it possible to drive RTC_XTALI  with external clock with dc level of 1.8V? since ensuring that external clock match VDD_SNVS_ANA will increase the design complexity. Also 1.8V is below the absolute  maximum rating of clock inputs. Re: RT117x Driving RTC_XTALI using External oscillator with 1.8V output Hi @Marwan, As stated in the Hardware Development Guide for the MIMXRT1160/1170 Processor, if you want to feed an external low-frequency clock into RTC_XTALI, the RTC_XTALO pin must remain unconnected or be driven by a complementary signal. The logic level of this forcing clock must not exceed the VDD_SNVS_DIG level. Additionally, the i.MX RT1170 Crossover Processors Data Sheet states that VDD_SNVS_DIG has an operating voltage range of 0.81 V to 0.95 V, with a typical value of 0.85 V. This means that a 1.8 V signal would exceed the VDD_SNVS_DIG voltage level. Best Regard, Pablo

SJA1105S+TJA1120A+RTL8211FI The RTL8211FI can obtain the PHY address through MDIO/MDC and access the internet normally, but the two TJA1120A cannot obtain the PHY address through MDIO/MDC nor access the internet normally. What is the reason for this? Is there any hardware that needs to be adjusted or modified? 1. Utilize the NXP i.MX95 SOC to externally connect three network card PHYs: one RTL8211FI and two TJA1120A, where the two TJA1120A are externally expanded through SJA1105S. 2. Resource allocation: (1) Assign ENET1 of NXP i.MX95 to RTL8211FI (PHY address is 001) (2) Assign ENET2 of NXP i.MX95 to SJA1105S, assign RGMII1 of SJA1105S to the first TJA1120A (PHY address 002), and assign RGMII2 of SJA1105S to the second TJA1120A (PHY address 004) 3. Please refer to the PDF for the schematic diagram Re: SJA1105S+TJA1120A+RTL8211FI Hello @leven , From the schematic review, one possible issue is the voltage level on the MDIO/MDC interface connected to the TJA1120A devices.   The TJA1120A VDDIO appears to be connected to the 1.8 V domain. Therefore, the MDIO and MDC signals connected to the TJA1120A should also be compatible with this 1.8 V I/O domain.   However, in the schematic the MDIO/MDC signals to the TJA1120A devices appear to be routed through the U20 level translator. The ENET1_MDIO_BUF / ENET1_MDC_BUF side, which is connected toward the TJA1120A devices, appears to be on the 3.3 V side of the level shifter. This would create a mismatch, because the TJA1120A MDIO/MDC pins are referenced to the 1.8 V VDDIO domain.   This may explain why the RTL8211FI can be accessed correctly, while the TJA1120A devices cannot be detected over MDIO. The RTL8211FI MDIO/MDC connection appears to be on the 1.8 V side, which matches its configured I/O voltage.   Please check the MDIO and MDC voltage levels directly on the TJA1120A pins with an oscilloscope. If they are driven at 3.3 V while the TJA1120A VDDIO is 1.8 V, the hardware connection should be corrected so that the MDIO/MDC signals use the same voltage domain as the TJA1120A VDDIO. Best regards, Pavel

Looking for Plug & Trust MW v02.16.00 for SE050 Project Hello everyone, I am working on a security project integrating the EdgeLock SE050 with an ESP32 running ESP-IDF v4.1.2 over I2C. My goal is to read the device certificate from the SE050 using PlatformSCP03. The reference source code I am using was written specifically for Plug & Trust MW Release v02.16.00. However, I can no longer find this older version on the NXP portal. When I download the newer v3 or v4 packages, I consistently run into build errors on ESP-IDF due to directory structure changes, missing header files, and SSS_MALLOC incompatibilities. Does anyone happen to have an archive of Plug & Trust MW v02.16.00 or know where I can download this legacy version? Alternatively, any advice on how to compile this project with newer Middleware versions would be greatly appreciated. Thanks in advance
