So, it crashed at:
1: @ Code is running at a vm address that is the same as its
@ physical address. Now disable the MMU.
nop
This means that haret was unable to map the "trampoline" code to the
same physical and virtual address. This is done earlier in the
mmu_trampoline function:
@ Turn off mapping for this code
mov r1, r4, lsr #20
mov r0, r1, asl #20 @ r0 = funcaddr & 0xfff00000
orr r0, r0, #0x00000C00
orr r0, r0, #0x00000002 @ r0 |= 0xC02
str r0, [r5, r1, asl #2] @ mmu[funcaddr>>20] = r0
I'm not sure why it didn't work. Maybe the output of "dump mmu 1"
will indicate something.
