Hello,Would it be possible to have an updated guide on how to use a custom device tree within my own layer for latest STM32MP1 Ecosystem ?The one provided here "How to compile the device tree with the Distribution package" is clearly outdated, as th...
Hello,We're trying to boot our prototype which contains an STM32MP157FAA.Unfortunately, we didn't implement an oscillator/quartz on the board, so we are unable to use HSE and can only use HSI.We have access to USB1, USB2, SDMMC3, and UART4.Is there a...
Hello STM32 Community,I hope this message finds you well.I’m currently working with an STM32 Linux board and have encountered an issue where the TSV Flashing Service fails and the code is not dumping correctly. I would greatly appreciate any assistan...
HiI have recently been working on the board model mentioned in the title. At the moment I have a problem with two things:1. when trying to debug the kernel drivers, the kernel is inactive for a period of time which causes the watchdog to run. This be...
Hello to everyone!We have develop a System on Module board based on the STM32MP153AAB. Currently it have a custom Yocto Image build, that it's working. The process followed almost all the steps in the wiki for the STM32MP157F-DK2 discovery kit, howe...
I want to test the memory by using U-boot.I'm reading the DDR memory from 0xC0000000 to 0xE0000000 with the pattern 0xFFFFFFF. But I don't have premision to read the memory. How can I solve this issue? STM32MP> mtest 0xC0000000 0xE0000000 0xFFFFFFFF...
