RE: Load Redboot RAM through serial


I was thinking more along the lines of actually starting it through the
serial port.  eg. loading it as the boot program.  I need this because
we're changing FLASH from intel to AMD am29xxxxx.  So, using another
boot monitor won't work because you have to be able to program flash in
the first place.  Since all the boot/debug monitors for the board are
designed for the flash that's on the development board, I won't be able
to use that flash.

In particular, I would like to be able to start a RAM version of RedBoot
by loading it through the serial port.  I could then modify just the
Redboot source to use the FLASH that we are using.  This would be all I
need since I could then write a ROM version of redboot to FLASH for
startup.

I've done this on the ARM Integrator Board.

I Used default redboot template then change startup to RAM. Loaded the
image
with the ARM Boot Monitor et voila...
