It just seemed odd that the output was:

Connected to ARM RDI target.
gdb.ini:3: Error in sourced command file:
Invalid download offset: files/red hat/eCos/examples/kalle.out

Which implies that it was interpreting "file/red hat
eCos/examples/kalle.out" is a download offset. But instead I suspect that
it's just the error message output that is getting garbled because of the
space in the filename.

But if you have a different app that works,certainly compare your objdump
output with that, particularly given Lewin's comments.

Interworking with Angel has not been a priority due to its proprietary
nature, dearth of documentation and unreliability.

But we've made it work for the PID I believe. Check through the ARM HAL for
the option CYGSEM_HAL_ARM_PID_ANGEL_BOOT to see what is involved.
