I am building a custom Yocto image for STM32MP1 (STM32MP157) using ST OpenSTLinux (dunfell-based) and I am facing a persistent U-Boot build failure.Environment:SoC: STM32MP157 (custom board)Yocto: ST OpenSTLinux (dunfell)U-Boot: v2020.10-stm32mp-r2.2...
I've got an STM32MP135AAE3 for which I'm writing my own FSBL. It's basically working!There are two scenarios:1) Chip set to serial boot; the BootROM wakes up and I use STM32_Programmer_CLI.exe to send it my FSBL which it stores in SYSRAM, BootROM th...
Hello,unlike the STM32MP157F-DK2 the STM32MP257F-DK is not equipped with an Touch/LCD.Is it possible to use an identical/similar LCD with the STM32MP257F-DK (that means: are the appropriate connections on the board)?Marc
Linux kernel, Yocto project, etc. each has their LTS strategy, does ST has similar plan for its OpenSTLinux?
Hi,I am trying to understand and test secure boot on STM32MP1. I was able to compile and boot unsigned tf-a. boot failed as expected as it is not verified.generated keys.Now how to burn these below hash file? can we burn into flash and test without u...
Hello Team,I am currently working on QuadSPI with MDMA, but I am unable to locate the driver code for this functionality.Could you please provide the required driver code?For reference, I am working on the STM32MP133F series.Regards,Sreedhar Kaduru...
Hello,Is there a list of supported/recommended displays that are compatible with the DSI connector CN4 on STM32MP157D-DK1 please?Kind regards,Al
I've got a custom board with an STM32MP135AAE3 talking to an eMMC (THGBMTG5D1LBAIL if it makes a difference). I've discovered that if I write from SYSTEM to the eMMC using DMA (HAL_MMC_WriteBlocks_DMA) it works fine, but if I use anything in RAM (SRA...
Hello ST Team,I am evaluating the STM32MP215F-DK with the recommended M.2 Wi-Fi/BT module (Embedded Artists EAR00409 / Murata 2EL). I have encountered two critical issues that prevent the Wi-Fi features from working out-of-the-box with the standard S...
Hi,We are trying to make use of the ethernet interface in this fashion:- The board is a custom one with a soldered module from Karo, the qsmp-2550, that includes an stm32mp255fa.- The eth2 is connected to a PHY (TI DP83869HM) in RGMII.- The PHY is th...
