I am porting a boot from sequoia. I have use the BDI3000 to load the u-boot.bin and flash to norflash. I can trace the codes by BDI3000 and receive the u-boot info from uart as following. but when I try to power on and run the codes itself but not use BDI3000 to send "go". there are not any characters from the uart port. I have no idea to find the bug. have any one can give some advice?
