Starterware: customize board with ti-am3352 main-chip, u-boot issue

Tool/software: Starterware

Hi all,

I have a customize board, the main chip is am3352, I try to boot it up.

I use am335x-starter kit(am3358) before, and worked perfectly,

In this case(am3352), I put the am335x-starter kit's MLO to my customize board(am3352),

but nothing message I can get by console.(just show CCCCCC....)

I think that I can get the console message(U-Boot SPL-201xxxxx) at lease, but no

What should I do?

ps: my customize board's console is common serial
