Hi Nikolaus,

 

Looks like you didn't damage the u-boot for one of the bricked minibooks. 
Although it looks like there are some issues with ecc/nand.

 

The dev/mtd1 contain the binary content from the uImage. You can use the uImage 
from the manufacture from the minibook. alpha400, letux400, trendtac(site is 
not working..), onet.

Check the one from elonex below (you only need the uImage 2MB, it's in the 
146MB zip file) :

http://www.elonex.com/support/products/onet/lnxonetrecovery.shtm

 

I have done some uploads in the past:

uImage [1MB] [url=http://www.divshare.com/download/6352899-cc9]DivShare File - 
.uImage[/url]

minifs [2MB] [url=http://www.divshare.com/download/6352758-aac]DivShare File - 
minifs.img[/url]

recovery elonex for trendtac 
[url=http://www.divshare.com/download/6352739-d3c]DivShare File - 
recovery.img[/url]

 

Put the items (uImage(without .) , minifs.img, recovery.img)  on SD card (1st 
partition vfat):

boot from SD keep press leftshift, leftfn, leftctrl. Just to try if uImage 
boots. 

leftshift + leftfn + F1 should restore the uImage to /dev/mtd1, this only works 
for kernel 2.4 uimage. 

leftshift + leftfn + rightshift restores the minifs.img to /dev/mtd3

Afterwards F3 recovery works for any recovery.img (which is a tar.bz2 from any 
distro)

 

For kernel 2.6 we need to copy uImage manually with, cat uImage /dev/mtd1, but 
first any nand ecc issues need to be resolved. good luck with JTAG setup.
