[microblaze-uclinux] Continued Problems With U-Boot (EDK 9.1.02, Spartan 3E Dev. Board Rev D)
I've been working for a week now trying
to use the following tutorial: http://developer.petalogix.com/wiki/BoardGuides/Custom/Tutorial,
as well as prebuilt configurations (gave up on that due to the fact that
it was built for the Spartan-3E Rev C board (I'm using Rev D)).
I've followed each step closely and
have consistently run into the same problem: when FS-Boot finishes
loading the image and says "running image..," nothing happens.
I've added code to fs-boot to verify that the image location and
the first S record match, as well as that the location is actually in the
range of the DDR ram on the board.
I've also checked my jumpers (tried
both in the jumper,jumper, jumper and the no jumper, jumper, no jumper
state) with no improvement.
I figured out that the External Memory
Flash RAM IP had to be the NON-"mch" version to allow the software
configuration dialog to select it. I'm in the process of trying again
with using just the non-"mch" version of the DDR IP as well.
I've used kernel 2.4 (following above
directions to set up menuconfig) and 2.6 (the config seems pretty much
done there) and neither have done anything different.
I'm down and a little lost, but not
out and could use a jumpstart or a pointer to the next step in troubleshooting.
My quandary is that I really need to be done with loading up an OS
and actually demonstrating it doing something next week, and yet I'm nowhere
near that. I'm not totally familiar with the available tools to debug
microblaze as of yet, so any information or pointers to get started in
actually investigating what's happening. Any response would be greatly
