Hi @WHe.1 ,

Can you share exact reference of STM32MP15 sample and eMMC please ?

I understand you succeed to flash the eMMC with CubeProg right ?

Please share the log from SD Card boot .. it might provide us some insight about your platfom configuration setup.

Hi @WHe.1

In case of low level boot failure, please share Bootrom log. Please have a look to https://wiki.st.com/stm32mpu/wiki/STM32_MPU_ROM_code_overview#Debug_and_Error_messages

and

https://wiki.st.com/stm32mpu/wiki/STM32_MPU_ROM_trace_analyzer

If you don't use default eMMC pins, please share OTP3 and OTP5-7 values you setup.

Note that some eMMC won't boot with silicon Rev.B. See ES0438 for details.

Regards.
