I downloaded the kernel and tried it. It starts booting, but it hangs
right after initializing the the OpenPIC. :-( I'll download the source
code tonight and try to look at it, although I don't have much hopes
gotta learn though.
Is there any book that you recommend to get me started? Any other
docs/tips?
Oops, I should have included the sandpoint switch settings. For
this version of the kernel, the sandpoint switches must be set as
follows:
S4,S3: up, down
S5: down
S6: down (yours is probably up which is why it hung in openpic)
Try this and see if it helps.
It did! The kernel boots fine now all the way through.
Thanks a lot!
Another question: what would be the best way to go about booting Linux
from the flash? Would flashing the kernel in instead of the dink32
monitor do the trick, or does dink32 do some important initializations
that are needed for the kernel to boot?
Yeah, at the moment, it does rely on DINK to do some initial setup (memory
controller, et. al.). If you want, you can put that in the code yourself and
then you can get rid of DINK. If you don't want to do that, you can still put
the kernel in flash (somewhere that doesn't overwrite DINK or the execption
vectors) as long as you have enough flash on your PPMC module. You can then
do something like "env BOOT=<address>" to cause DINK to automatically jump to
that address--that's should be the address of the linux ppc bootloader--and
the kernel will boot up for you without your intervention.
