Hi, i created a basic m33 app via the default stm32mp257f-dk board project. When tring to boot the m33 app from the RFS, th m33 powers up and boot starts, however the kernal crashes with the below error. Any help understanding the nature/fix for the ...
We are working on a custom board based on STM32MP257F-AI3. We flashed an X-Linux RT patched image via SD card in boot mode 0001(A35-Master), and in the ST Cube Programmer flashing completed successfully with a "download successful" pop-up in when boo...
Hello ,I have developed a custom board using the STM32MP157DAA1. Its design is very similar to the STM32MP157-DK2.I am trying to build and boot TF-A and OPTEE. However, I am encountering an "I/TC: Forced system reset PSCI" error, which causes the sys...
Hello ST community,I’m an embedded software beginner working with the STM32MP257-DK board and OpenSTLinux (Yocto). I need help getting USART6 working on the external GPIO connector (PF13 = TX, PF14 = RX — CN5 pins). I have rebuilt device trees and co...
hello ST: I used the stm32mp257 platform for KGDB debugging and found that it always resets the watchdog. I tried to disalbe the relevant nodes in the device tree of the kernel and optee: ///kernel： &arm_wdt { /*timeout-sec = <32>; sta...
I am creating a custom yocto image on a STM32MP157F-DK2. I am using the meta-stm32mp layer as apart of the bitbake build. Yocto version : Scarthgap When I run bitbake I get this failure ERROR: hydra-image-1.0-r0 do_rootfs: Postinstall scriptlets of ...
We ordered an STM32MP257F-DK evaluation board - DigiKey part number "497-STM32MP257F-DK-ND" - on 25 September 2025 and had it delivered to Zürich.On 15 October 2025 we ordered the same ST STM32MP257F-DK evaluation board with DigiKey part number "497-...
Hello ST team,I’m working on a custom board based on STM32MP135F SoC, with GigaDevice GD5F4GM8UExxG (512 MiB SPI-NAND) connected on SPI1 interface.I’ve successfully integrated this NAND flash in U-Boot and Linux (Yocto build), but the board fails to ...
I am following getting started guide of this board STM32MP157x-DK2 https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Create_a_simple_hello-world_application When I am connecting an ...
This page mentions that you are supposed to use tar xf for SDK extraction. Unfortunately this doesn't work for the latest SDK 6.6 (scarthgap), it looks like the SDK is just a tar archive and not compressed. $ tar xf en.SDK-x86_64-stm32mp1-openstlinux...
