Does it say load flash or (more likely) RAM version first? There is a
flash (bl.hex) and a RAM (bl_ram.hex) version. The flash version lives
at the beginning of flash at 0x0 and protects itself from being
overwritten. Link your software-to-be-flashed to 0x4000 (don't forget
the '-n' option when linking) and it should work. Or use the RAM
version to overwrite flash at 0x0.

Not sure, but I think it compiled with Winarm under Cygwin as it is.
