Hi,
I am trying to boot my 8641D based PowerPC board. I am having trouble
booting it.
Following code snippet is from head_32.S.....
lis r4,[EMAIL PROTECTED]
ori r4,r4,[EMAIL PROTECTED]
tophys(r4,r4)
li r3,MSR_KERNEL & ~(MSR_IR|MSR_DR)
FIX_SRR1(r3,r5)
mtspr SPRN_SRR0,r4
mtspr SPRN_SRR1,r3
SYNC
RFI
/* Load up the kernel context */
2: bl load_up_mmu
My code successfully reaches up to the RFI instruction, but never to "2:
bl load_up_mmu". I am not using any debugger (used an LED write to
address to figure it out) in this situation.
Any suggestions on why my execution sequence never reaches the "2: "?
Appreciate any help.
Thanks
Siva
