[Skyeye-developer] Booting a uClinux for Blackfin BF533 in Skyeye -- lots of core dumps, little success

[sergey bryukov]

Hello Kang!
I downloaded skyeye-1.2.4 and skyeye-testutils-2.3. Then I try to run
uClinux image: skyeye-testsuite-2.3/uClinux/bf533/ skyeye -e linux

and I have stopped emulation with string below

EXT2-fs: unable to read superblock
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(31,0)

What's wrong?
Thanks!
