Hi
We are trying to bring up our custom P2010 RDB based board. boot is NOR based and we cannot get past the rfi below. lis r6,MSR_IS|MSR_DS@h ori r6,r6,MSR_IS|MSR_DS@l lis r7,switch_as@h ori r7,r7,switch_as@l
mtspr SPRN_SRR0,r7 mtspr SPRN_SRR1,r6 rfi
switch_as:
We end up with a TLB exception no matter what we do, even after applying this patch.
Did you apply the entire patchset, and define CONFIG_SYS_PPC_E500_DEBUG_TLB?
