I am trying to get this board up and running again after being away from it for a while, but I've been running into problems trying to boot from the SD card. I followed the instructions from the wiki here: https://wiki.st.com/stm32mpu/wiki/STM32MP15_...

@PatrickF I tried v1.2.0 and v1.0.0, same results.I'm not exactly sure where to find board reference number and serial number, I don't have the original packaging with me at the moment (I can get it if necessary). Hopefully this picture captures it?...

Hi @Community member , thanks for looking into this.I have tried a SanDisk Edge 16 GB Class 10, SanDisk Ultra 32 GB SDHC Class 10, and a Kingston 8 GB Class 4, all with the same results.

The watchdog solution should be sufficient until we are ready for Linux to manage it.The use case is that some settings of our firmware require a reset and to support our messaging protocol (firmware will receive a message to reset itself).Thank you ...

@AntonioST I need the M4 to reset when I call NVIC_SystemReset. I don't know how to set the RCC_MP_GCR BOOT_MCU bit from the Linux side of things, and the manual says it cannot be set by the MCU, so how do I set it? I am not seeing anything in that...

@AntonioST What is the proper way to set BOOT_MCU to 1? Can you do it from Linux?

Re: Hello. We are trying to reset MCU from within MCU by asserting SYSRESETREQ it in Cortex M4 AIRCR register (by calling NVIC_SystemReset). After that the MCU halts and FW is not running.
