I had a look at what's going on with the debugger - hello_world

to an incorrect address (0xff97b8). This happens at the very
start of the
program.
This probably means that the stub code which exports U-Boot functions for use in stanbdalone applications is incorrect and/or incomplete for your platform.
I've stepped through the code with the debugger and the stub code seems to be working fine. I set the PC to getc() in hello_world and I was able to jump to serial_getc() in u-boot. D7 is pointing to the start of global data, as expected.
However, I did notice that both the u-boot monitor and the hello_world app are using the same vaue for A5 when jumping to other functions - hello_world is pointing to u-boot's data/bss section. Does anyone know how I can get the hello_world app to load it's own A5 value before it begins its own processing??
I've read through the README and DULG I've scoured the mailing
list archive.
I still haven't been able to come up with a solution. Any ideas
as to what I
could be doing wrong??
Please see doc/README.standalone and check the implementation for your arch.
