Post How to debug U-boot on Trimslice?
Hi,
I want to config and compile a new U-boot for Trimslice by myself and debug it, but I don't know how to debug the U-boot on Trimslice.
Is there any tool to doing that ? where can I get them?
ANY reply will be appreciated very much.

Thanks.

I'd offer an old school debugging using printf.
Another approach is to use a Flyswattwer JTAG debugger: http://www.tincantools.com/product.php?productid=16134 , moreover you have made it work with a TS.
Unfortunately, I did not get to make it work with my TS, other than send a reset signal to my board.

Regards,
Valentin.

Hi Valentin,
Thanks for your reply,
Unfortunately, I have no budget for buying a Flyswattwer. You mean there is no other solution for debugging U-boot other than adding printing code in the source code of the U-boot?
Have you ported U-boot to TS? I am a totally green hand in doing that , can you introduce about the steps briefly?
Best regard.

printf and crash dump analysis is the only options for now

Yes, I have.
