Greetings:
I'm attempting to bring up a new board (our custom hw) and am blowing an
Instruction TLB error in head_440.S where the original TLB for SDRAM
(u-boot and initial kernel space) is invalidated after we've switched to
0xc000_0000.
the instructions:
3:/* iccci r0,r0 rcblach 12/19/02 clear all caches again on 1/17/03
I took out these changes
dccci r0,r0 again clear all caches */
cmpwi r23,62
beq 4f
li r6,0
tlbwe r6,r23,PPC440_TLB_PAGEID
sync
The exception hits when the sync is executed.
I hope this hasn't been discussed ad nauseum in the archives... I
couldn't seem to find it.
Kernel is 2.4.21
Any ideas?
TIA
Travis
