Hi,


Can you explain how you are accessing the SDMMC register?

Also, your SDMMC is 4-bit or 8-bit?


Regards

Tiwari

    After changing the emac setting in the dts, the boot continues without the problem during the SD card access.

    I don't sure what is the connection, but this is OK for now.
