yaffs problem while mounting Android mtd-partition

Hi,

I've installed the android image from friendlyarm on my board and want to
build my own kernel. 
I've got the 2.6.32.2 Sources from friendlyarm and compiled the yaffs
driver into the zImage. I've downloaded it and this is the result:

The prebuilt android-zImage works...
