I currently have two base boards, one of them is working, we call it board A for the sake of description, and the other one is under debugging, we call it board B. Now I burned the kernel into IMX6U normally on board A, and it also boots normally.But when I put the IMX6U in the B board, it keeps printing the following message and can't enter the system, can you tell me what causes it?
