Why are you trying to load a file to 0xb288?

What is the format of the file?  The 'load' command you list
will only work for S-record data.  If you are tring to download
any other sort of data (raw binary or ELF), the 'load' command
will fail.

So what does it do?  Can you send the output?

What is the platform?
How did you build the program?
Have you tried running the standard eCos tests in the same environment?

Our tools will automatically adjust programs to the appropriate
addresses.  Typical eCos programs will load at 0x10000 or 0x20000.

XXX-objcopy -O srec <ELF-file> <S-rec-file>
where 'XXX' is your platform type prefix, e.g. arm-elf-objcopy
