[microblaze-uclinux] uClinux freezes on boot XUPV2P
When I try to boot up uClinux using a newly compiled kernel it freezes
on me. I've copied the boot message below. I've spent a great amount
of time trying to narrow down the problem.
I ran the memory test included in your XUPV2P demo available from the
Digilent website and my memory passes all three tests. Without the
ICAP, I can use the image.bin from your example to load uClinux, so I
believe my implementation in EDK is correct.
If I used the auto-config.in produced from EDK 8.1 SP2, and keep all
of the default settings when building the image.bin file, upon
starting uClinux the root message freezes after "Freeing init memory".
This occurs both with and without the ICAP in the design.
I know that additional changes need to be made to allow for
CompactFlash support, but are there any changes (from the default
provided by auto-config.in) that need to be made in xconfig to allow
uClinux to boot up?
In your documentation for the demo, it says to use the BSP for EDK 7.1
SP2. Is this still the case, or should I used the BSP for 8.x at
