Now, I am use P1010 cpu in the system. I use normal uboot&linux image booting from nor flash, not secure boot and never touch sfp fuse in P1010.
Sometimes I find that the cpu cannot boot uboot and no uboot print info in the uart console. When I power off and power on it again, it is the same. Then I use codewarrior usb tape to connnet the cpu, but the codewarrior software ask for a 64bit response word, and I also do not known the word.
This problem is cased by hardware or software and maybe where? Can I skip this problem by disble secure boot completely and how?
