I want to boot my original board which STM32MP151CAA3 MPU is mounted on.
However, the following error occurs in the boot process and the process fail.
mmc0: error -22 whilst initialising SD card
I suspect that the description of User Code Section for sdmmc1(SD card) node in the device tree cause an error, but I have not known the cause of the error.
What could be the cause of the error?
I attach boot error log and original device tree sources.
Would you be able to lend your expertise.
Best regards.

Sorry, what board?
An ST supplied board, which one, or a custom board you designed and built?

Hi @Community member
Thank you for your answer.
I'm trying to boot a custom board that I designed and build.
STM32MP151CAA3 MPU is mounted on this board.
I suspect that the description of User Code Section for sdmmc1(SD card) node in the device tree cause an error.
But I do not know what I need to modify from the error message.
From this error message, are there any possible causes of the error?
I would like some hints what I should investigate further about this problem.
Best regards.
