Hi,

I have a fresh RedBoot (taken from CVS about 2 weeks ago) and a eb40
like board. I built it as ROM startup and loaded it to the board with
BDI2000. I get the prompt and I can issue commands...
When I try to load something into RAM, using load command, I don't see
any bytes loading. For example:
RedBoot> load -m ymodem -b %{FREEMEMLO} -r
gives me the "C" in console, and on the file transfer window from
minicom I get:
Retry 0: NAK on sector
until it gives me:
Retry 0: Retry Count Exceeded
Have you ever successfully uploaded s.th. to this board via ymodem ?
Have you tried xmodem ? Have you tried a minicom-alternaitve ? Have you tried
sb without minicom, like "sb filenameandoptions < /dev/ttyS0 > /dev/ttyS0" ?
As curiosity, does it help if you disconnect the serial cable as soon as you
get "C", then start the minicom-filetransfer, and then reconnect the cable ?
I do not know eb40 details and I do not yet know RedBoot details, but I know
there have been some strange interaction problems with minicom and sx
(xmodem) when using at91rm9200 firmware. One solution can be found there:

But maybe someone who knows eb40 and redboot better than me can help you
better.
