Hello,
on my custom board based on eb55 (also AT91M55800), I have the same
problem: Redboot works fine with all baudrates, but ymodem or xmodem not.
The highest speed I can use is 19200 baud.
Also Vince Z. has the same problem. Like him, I now also use TFTP instead.
The strange thing is that on the eb55 demoboard, 38400 downloads are no
problem.
Kind regards,
Juergen

Hello,
I'm trying to get redboot running with a console baudrate of 115200 on
an Atmel EB40A board.
First everything looks fine:
I can read the output from redboot after power-up, enter commands and
these things.
The problem is that file downloads via xmodem don't work with the higher
baudrate.
Any suggestions ?
Probably you are overflowing the receive buffer and so causing CRC
errors. Try a slower speed.
