[U-Boot-Users] what is wrong when calloc return bogus?

[Matthew S. McClintock]

Its loading from flash, copying itself to the middle of memory. We are
currently using a minimal version of RedBoot that came with the
development board to load u-boot to flash. The current setup we have as
I understand is JTAG via CodeComposer in windows. I don't have any of
this setup on my computer, but my college does so I do not have easy
access. Also I have tried to use the JTAG to look at memory with
CodeComposer but after u-boot starts on the board the debugging via JTAG
no longer seems to respond. I still have not had much time to look over
all the code so meanwhile I will keep looking until I figure out what is
going on.

Thanks,
Matthew
