I am trying to displace vxWorks as the OS of choice on several new designs.
This will be a tough sell...
Since vxWorks works, I'm confident that the hardware is ok. When I try to
flash the rom version of redboot using Mot's firmware, the board hangs. The
best answer is that I'm doing something stupid :)
any suggestions are appreciated

I Attempted to create rom.ppcbug and used the technique described at
http://sources.redhat.com/ml/ecos-discuss/2001-06/msg00477.html which
uses an srecord download

This didn't work, so I tried the binary image from the web.
Downloaded redboot_ROM_40.bin and programmed flash using
TFTP and compared w/ redboot_ROM_40.srec
