atmel at91rm9200: serial comms and loading u-boot

Started by dfx September 8, 2005
Hi,

I'm having issues getting serial comms working with my board; I have
traced clean  data pulses from the PC serial port to the Atmel CPU, and
put the CPU into debug mode after a power down cycle plus jumper
setting. So I know the wires are connected :-)

Need to load u-boot onto the board and so on ... any insights that
could be shared?

Thanks,
Manu

What board?

I'm not sure what you mean here. Did you boot from the internal ROM and got the Xmodem upload to work?

You have found Atmel's application note on how to reload U-boot after it has been lost? -- Stef (remove caps, dashes and .invalid from e-mail address to reply by mail) Nothing increases your golf score like witnesses.
