[ECOS] Problem executing anything on IXP425 based board, redboot is the bootloader

[Ajit Mittal]

Ihave a board with total RAM of 32 MB, 2 chips of 16  MB each. It has
8 MB flash.
It has redboot bootloader and platform is IXP425 processor

Booting is fine. I am able to load the program fine to memory but
executing gives me an error grabage output on serial output after
executing go or exec command like this
"$T050f:01000000;0d:01fc0fec;#d6". I think memory/interrupt of
the board is bad. How to test RAM.

If suppose RAM is bad. Is it possible to modify redboot and burn it again and
then use only 16MB RAM.If yes how to do that or how to troubleshoot.

Thanks

This is not garbage; it's RedBoot telling you that there is
a problem executing the code.  This is a GDB protocol string.
You could try connecting via GDB to find out why (search the archives)

More importantly, tell us how you configured eCos to build
this program.  What steps did you use to load & execute it
(the actual RedBoot commands and the output when you run them).

Without this level of detail, we'd just be guessing...

You've still not provided the info about how you configured your program.
Be specific - prose is inconcise and error prone.

Also, what are the *exact* commands you typed to RedBoot?
