Hi Nikolaus,
Downloaded the latest git sources. git clone
git://git.goldelico.com/letux-400.git
Two issues, may need additional fix or upload of your local patches:
- issue with nand mounting. Showing errors on yaffs2 tragedy.. cause kernel
segfault and stuck
- The key's to startup from different boot don't work, alway's rooted from
/dev/mtdblock4.

Hi Nikolaus,
I have simular result. Used df to see the size and available space on all
partitions.
- It looks like the /dev/mtdblock3 is in use by jffs2 blocks.
dmesg shows some prioritised blocks when mounting as yaffs2. So better to mount
as jffs2 I think.
So far this kernel 2.6.24.3 and the updated sources are very usable now. ;-)
Grt Ruben.
