I have build several boards with the same design which are based on AM3874 processor. In some boards, using debug serial UART, I can see that on some boards, the processor can boot from SD card but on some other boards, the processor output some CCC and then hangs. In one board, I can see that the it starts booting from SD but then after outputting some information about UBoot, it output some garbage and the hangs (no output on debug UART).
How can I find what is the problem?
Is there any documentation on how to bring up a board?
is there any software that can test board and different part of it (assuming it is similar to EVM board from the design point of view)
Is there any information similar to this http://processors.wiki.ti.com/index.php/AM335x_board_bringup_tips for this processor?
Is the above document valid for this processor?
