Re: [microblaze-uclinux] u-boot error 'end address not on sector boundary' on ml403

[Aleksandar Sutic <asutic@xxxxxxxxx>]

Nicolas,

I found out what was the problem. Actually, I enabled the MMU support in kernel, but I omitted to do it in XPS (MicroBlaze IP configuration).

After this modification (no MMU support for now), kernel starts booting but I encountered similar issue with what you described at http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2009/05/msg00044.html (kernel log is shown bellow):

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

At first I also didn't have CONFIG_ROOT_NFS=y, but even after I followed the instruction in the thread, still similar NFS problem exists. Or is it really NFS?

Do you or anybody else have any idea what am I doing wrong? Could you share your config with me again? I didn't get it in the attachment.

       Thanks a lot, Nicolas. I'll check everything again and post my findings here. I really hope that everything will start to work. It would be a truly nice start of the week :-).

       I'm using EDK 10.1 and, if I recall correctly, the frequency is 100MHz.

You may try to adapt my linux-2.6/.config.
Our boards are similar and peripheral adresses seams to match ...
See attach files if it helps you find what is missing.


maybe this is wrong :
CONFIG_XILINX_UARTLITE_0_SPLB_CLK_FREQ_HZ=50000000

if I compare with what you send my output of command
`cat linux-2.6.x/.config|grep -i uart` gives

What version of EDK are you using ?
Did you set all your system to run at 50MHz ?
Try 100.
