Hello,
I have a custom board based on the Freescale P2020 RDB. I am having trouble
getting through the entire boot sequence. Basically, I can't get a breakpoint
to hit in board_init_r.
I can get a break point in the "in_ram" section of start.s though. This
executes all the way to the following loop
/*
* Now adjust the fixups and the pointers to the fixups
* in case we need to move ourselves again.
*/
li r0,__fixup_entries@sectoff@l
lwz r3,GOT(_FIXUP_TABLE_)
cmpwi r0,0
mtctr r0
addi r3,r3,-4
beq 4f
3: lwzu ri4,4(r3)
lwzux r0,r4,r11
add r0,r0,r11
stw r10,0(r3)
stw r0,0(r4)
bdnz 3b
Basically, it spins through this loop for a while and eventually I get a TLB
exception. Is this just a cut and dry DDR configuration problem, or should I
be looking at my Uboot setup?
Thanks,
Kevin
