Hi, Matt:
I am using the same source code I guess and everything BUT USARTs works for me just fine (thanks Ulf). I have searched desperately through mail archives for any known USART problems but with no avail. It would help me tremendously if you could test USART on your board (if you have physical connector it must be simple) just as usual RS232 and tell me whether it works. It can be useful for yourself if you ever consider using USARTs. And could you please send me your u-boot/cpu/arm920t/at91rm9200/serial.c file just in case?
BTW, what USARTs (if any) are available on your board? At91rm9200-ek evaluation kit has USART1 connected to DB9 port.
Thanks a lot,
Leonid.

Hi all:
Does somebody have working u-boot code for USART on any at91 Atmel
board
(best of all at91rm9200-ek/dk)? The code in serial.c of standard
u-boot
tree doesn't work for me...
You don't mention what build you're using.
With respect to the standard tree, I'm using 1.2.0 patched from Ulf at Atmel, and it all works wonderfully (although I don't use USARTs in u-boot for this project). Check the archives of this mailing list for Ulf's announcements.
Regards,
Matt Gessner
