hi all.
i am using DM365 on my custum board, i am trying to flash UBL and U-BOOT through UART using TI' S serial flash programmer, some days before its working fine, but now a days its giving problem like as below
this is what i understood from the flash process,
1. Nand Erase is working fine
2. Board is accepting UBL but when its trying to boot that UBL through UART its failing and going into infinite loop(means UBL is accepting but U-boot its not going to accept)
if something is wrong in my understanding about board boot procedure, pls correct it,
Actual Debug prints are as follows,
