Hi ST expert:

​

​This issue has been solved, but I am now experiencing AVB related issues that prevent the system booting from sd card,I have been disable BOARD_AVB_ENABLE := false in BoardConfig.mk, How can I turn off dm-verity in build?

Also, can you give me a boot log for reference, I don't have a DK and EV development board, thanks~
