Resolved! Using Only the M33 on the STM32MP2: Feasibility and Peripheral Support
Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe wou...
U-Boot build fails in Yocto for STM32MP1 with “work-shared source is not clean” error
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...
Not seeing boot context in FSBL
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...
Resolved! LCD Touch Display for the discovery kit STM32MP257F-DK
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
What is OpenSTLinux's Long Term Support?
Linux kernel, Yocto project, etc. each has their LTS strategy, does ST has similar plan for its OpenSTLinux?
Test Secure Boot on STM32MP157A
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...

Resolved! DMA to eMMC can only talk to SYSRAM but not RAM (SRAM1, SRAM2, SRAM3)
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...
