EB42 AT91 redboot load problem


Hello,

I've already searched the newsgroup/web for a solution of the following
problem, found the question twice, but without any answer helping me.

My system is an EB42 with an AT91 processor. I flashed redboot as documented
with angel and gdb. The RAM-version of redboot was able to load srec-files.
The ROM-version, which I flashed with the RAM-version, isn't able to load
files. The failing command is

RedBoot> load -m ymodem
CCC

I tried out every protocol (x and ymodem), two baud-rates (38400 and 115200)
without success and also the -r option with -b pointing to free RAM. Even
tried DOS and UNIX EOLs for the srec-file.

Using a single-line srec-file sometimes is ok.

GDB runs fine over a 115200 baud link with that redboot!

First lines of srec-file:
S3150200800018F09FE518F09FE518F09FE518F09FE538
S3150200801018F09FE50000000018F09FE518F09FE5B4
S31502008020408000021C820002408200026C82000232
S31502008030888200020000000088830002508300024A

My redboot:
RedBoot> version
RedBoot(tm) bootstrap and debug environment [ROM]
Non-certified release, version UNKNOWN - built 19:03:32, Jun 25 2004

Platform: Atmel AT91/ACC01 (ARM7TDMI)

RAM: 0x02000000-0x02040000, [0x02006a00-0x02040000] available
FLASH: 0x01000000 - 0x01200000, 32 blocks of 0x00010000 bytes each.

Any ideas?

Thanks in advance,
Volker
