Hi Supporter,
We follow 8MMINID4 to design a new HW and replace NAND to eMMC as below.
We can update image successfully by using UUU tool. Please check UUU log and uuu.auto for command list.
After reboot, it will hang up at u-boot and complain "MMC Device 1 not found".
Can you help to check and advise?
boot up log:

Solved! Go to Solution.
In the software the uSDHC3 clock is not initialized in default. We must let CONFIG_SYS_FSL_USDHC_NUM=2 to run the uSDHC3 clock initialization code. How to add you can refer to the thread by my colleague.
Which uSDHC are you using for emmc? uSDHC1?
Any update?

Thanks a lot. It can enter kernel now.
Good news it works now.
