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

Any ideas?
Thanks in advance,
