Hi all,
Thanks Dave and Ben, I can now boot with the latest U-Boot.
I was incorrectly flashing the image to the older 0xFE700000
location.
Since this will likely bite someone else, I would like to
create
u-boot/doc/README.mpc8349emds
since there isn't one there already. Is there a standard
style I should follow, or can I just work in the style of
README.mpc83xxads?
Something like this:
1. U-Boot build procedure
2. Upgrading to the latest U-Boot from the Freescale 1.1.3
patched U-Boot delivered on the board
3. Configuring U-Boot for the board operating in PCI
agent mode
I've now performed 1 & 2, but haven't looked at 3.
Using od, I see that the HCRW at the start of the U-Boot
image is for PCI Host mode with arbiters enabled,
i.e., the RCW words are (0x04040000, 0xB060A0000).
For agent mode RCW words would need to be
(0x04040000, 0xB060A0000). So when I get to the
PCI agent testing stage, I'll take a look in
the U-Boot source to see is there is a config
option to select agent mode. If you guys have used
that mode, or know of any other changes I would need
to make, please feel free to comment.
Thanks guys!
Regards,
Dave
