I offer our solution to the problem as an additional data point. I added a command

to the boot rom code that downloads a file to any supplied address via tftp then

jumps to that address plus 0x1000. The offset of 0x1000 is to get over the

ELF header. In this case, I leave the the LINUX build environment alone

and still get a quick boot turnaround.

The commercial BDM/JTAG debuggers are almost worthless after the MMU

is enabled. Only in a "after the fact" case are they of any use. We, collectively,

need to continue to bellyache to the vendors about the short coming.......
