We have solved the problem.
What we do is :
1. uuencode the gdb_module.bin to text file
2. Download the image under boot prompt
3. Flashwrite the image to the right position.
Then there isn't error when the eCos is plugged in.

At a guess, Angel probably expects images to contain their own checksums,
probably at the end. You would need to find out what Angel's requirements
are, i.e. what algorithm is used, where it should go etc.
