we have develop RV1106 Based customized Board
Dear Team,
We are facing an eMMC initialization issue on the RV1106 board during normal boot, with the following error reported in the boot log:
mmc0: switch to bus width 8 failed
Although the firmware image is being flashed successfully to the eMMC in boot mode, the board encounters this issue during normal boot and waits for the root device /dev/mmcblk0p7.
please check the below log file and let me know how to solve the issue
