AW: AW: AW: [microblaze-uclinux] Download problems (No target with id: -1)
Hallo John,
I switched from CentOS 4.4 back to CentOS 3.8 and recompiled the kernel there.
Then i used the new Image and now it works!
Perhaps, it's because of the kernel version (now 2.4)

That all looks correct - the cache size (16kb) is different from the cacheable range (which should normally cover the entire off-chip memory space as you have it).
You might try disabling the caches, see if that makes a difference. You can do this either by removing them in the MHS file and rebuilding the HW, copy the new auto-config across, and so on. Or, you can just manually edit the auto-config.in file inside the kernel, run "make oldconfig clean dep all" and rebuilt it that way.
