Hi folks,

I'm porting the avnet5282 to the 2.6 tree. It boots ok, but I've some
troubles with the flash device. The bootlog shows me uclinux don't found my
flash device. Also he mount the uclinux partition. The 2.6 settings are the
same as the 2.4. Is selected the uclinux partition in both. The avnet5282.o
file is generated without problem.  I don't understand why is creating this
uclinux partitions but not my device flash partitions. I thinl the problem
is here, but I don't know what I have to do now. Any idea will be welcome.

This is my bootlog:
