We are using a custom board with STM32MP257F using M33TD flavour, booting from QSPI SNOR. My understanding is that when reset is released, the processor runs some on-chip ROM code, which copies the FSBL from external NV storage into some on-chip RAM ...
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 ...
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...
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 ...
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 ...

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...
I'm new to STM family, we are bought STM32MP157F-DK2 Discovery kits.We need OpenSTLinux image file where we can get
Hello I am planning to use STM32mp257Fak3 with DDR3L (16bit and 32 bit saperately),can you suggest some DDR part no and it's sonnection.
I am trying to drive a 5 inch 800x480 touch display from waveshare using my STM32MP257F-DK development board. My Linux distro is a custom one built using Buildroot via bootlin support.When running `modetest -M stm -c`, I don't get any resolutions pri...
