Can't boot from SD card on STM32MP157A-EV1

CC · ‎2020-10-15

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_Evaluation_boards_-_Starter_Package

I tried flashing in DFU mode:

I have also tried populating the SD card directly with dd, the results:

Hi @CC ,

Very weird and unusual issue ...

Could you share SDCard memory model you are using ?

Do you have a chance to try with another one ?

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.

Hi,

Could you share precise boards references and serial number ?

To confirm if there is a undetected regression in our deliveries, could you give a try with the previous starter package ?

e,g, selecting v1.2.0 on this link :https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32-mpu-openstlinux-distribution/stm32mp1starter.html#get-software

@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? Thanks

Please check carefully that all jumpers are set to their default (according to board UserManual).

Maybe worth to try to Flash and Boot using embedded eMMC.

Sound very strange that board is partially booting, you might have a weird HW issue around the SD-Card. BootROM and first level boot are using 1-bit data, then 4-bit data is used at one point of time, which might explain that the boot is starting ok then failing.

Regards.
