All,
I am having issues getting EMAC1 working alongside EMAC0. We need
both EMACs running at the same time in U-Boot (U-Boot handles the PHY
configuration, since the VxWorks implementation of PHY initialization
is buggy).
What I have done is this:
In net/eth.c I have modified the eth_init(bd
All,
I am experiencing a machine check on a custom AMCC 405EX PPC board. Our board
is based on the AMCC Kilauea evaluation board. We have a few of these boards
that are up and running, but I am trying to track down a machine check error on
a couple of them.
My question for you is this: when

That was my initial hunch

That is a good idea. I haven't thought of performing those tests. Are there
specific tests I can enable in the U-Boot environment for that?
We have been using a couple
It is my understanding that the 405EX CPU is not Book-E, however in
include/asm-ppc/processor.h line 390, Book-E definitions are used for the
405EX. Is this correct?
I am still trying to debug the cause of the AMCC 405EX Trap (see that thread
for more info) and found this. I was trying to see
I need to generate an assembly listing that contains all the assembly code
generated by the compiler. I have tried putting the standard GCC options in
ppc_config.mk, but cannot get the results I am looking for.
What I need is a listing file that contains the address (preferably with _start
