Can I use RiscWatch to load ppcboot?

Can I use RiscWatch to load ppcboot?

[byf]

Hello,

I am working for walnut 405GP, it has a ROM Monitor and RiscWatch.
now I want to use PPCBoot to overwrite ROM Monitor,
Can I use RiscWatch to load PPCBoot to flash or to ram and run it?

or can I use a kernel with mtd support to finish this?
I have no BDI2000.

Thank you!

You better ask such questions on the PPCBoot mailing list!

I have no idea.

You _can_ do it, but I don't recommend it.

In this situation  any  minor  error  will  render  your  board  non-
functioning without any other way of recovery but getting cccess to a
BDM/JTAG debugger.

hi

i currently use the riscwatch to load ppcboot into ram and then run it
from there
to do so i changed the start of code segment in board/walnut405/config.mk
to a
address in ram eg. 30000.
in include/config_WALNUT405.h i set th flash and monitor base to the same
address (CFG_FLASH_BASE, CFG_MONITOR_BASE)
load ppcboot with 'load file ppcboot',  set iar to the start address, run

hope this helps

p/s: please excuse the message format.

yes. I use the onboard SRAM walnut has a switch that exchange the flash and
sram address. So once you load it you can actually reset the machine and it
will boot just like you had programmed a real flash just don't tun the power
off :)
