Re: [microblaze-uclinux] Help - Spartan 3 port almost works

[Steve Sanders <akasanders@xxxxxxxxx>]

Can you post your .config file(s) and system.mhs file?

BTW, John - is there any way to get a corresponding .config file posted
for the demo image.bin files available on the web site?  Might help
some folks...

I just got uClinux going on a 3S400, so I know it can be done on a
Spartan 3. :-)

I had to check and double-check that kernel configuration options
matched various Microblaze settings that can be made via XPS.  Barrel
shifter, multiplier, divider, cache settings, etc. need to match.  I
posted my working .config file recently - you might check back a few
weeks in the mail list archives.

Running and passing memory tests is not necessarily an indication of
stable hardware.  I passed memory tests all day long for awhile, but my
kernel still wouldn't boot.  The big "gotcha" for me was needing to add
in a timing constraint on my system clock.

I don't have any experience setting up DDR with Microblaze, but DDR is
definitely tricky.  Any way you can squeeze into your 2MB of SRAM? 
It's more than enough to boot a small kernel.  Might help isolate the
problem.
