Hi everyone,
I have bricked my sheevaplug and succesfully restored it via sheevapluginstaller.
Now I have a different uboot version on my sheevaplug (now 3.4.19, before 3.4.16).
Everything is fine until I flash a selfcompiled kernel (which runs fine on 3.4.16).

jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000: 0x4255 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000004: 0x0001 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000003c: 0x4f71 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000200: 0x4255 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000204: 0x0101 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000023c: 0xb229 instead
Empty flash at 0x00000400 ends at 0x00000800
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000800: 0x1831 instead
....

and so on...
Is it possible to downgrade back to uboot-3.4.16?
I have some other sheevaplugs running this version of uboot.
Is it possible to make a uboot-image from those?
I really do want to use 3.4.16 because I do not want to change the kernel as it is installed on many sheevaplugs I would have to change. Sad
Please help me

Hi again,

I found a uboot version 3.4.16 here.
I could flash it on my sheevaplug, but the problem is still there.

What's going on with that plug? Am I doing something wrong?

Where did you get the older version of uboot? I'm still looking for anything other than 3.4.27
