Hi Neeraj,

1. Size and type of SD card
I tried a few other microSD cards from 2GB to 16GB, but this didn’t solve the problem.

2. Which MMC interface is the SD card connected to
I followed the DK2 schematics:
SDMMC1_D0 -> PC8
SDMMC1_D1 -> PC9
SDMMC1_D2 -> PC10
SDMMC1_D3 -> PC11
SDMMC1_CK -> PC12
SDMMC1_CMD -> PD2
uSD_DETECT -> PB7

I used both FlashLayout_sdcard_stm32mp157c-dk2-basic.tsv and FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv, with the same results.

Just out of curiosity, if you use a DK2 and remove the SD card before flashing the board with STM32CubeProgrammer, are you able to replicate the issue?

Thanks,
Verseau
