I found the Nokia Patch
This seems to be done for OneNand, while I am using Nand.
Regarding the pathes: That are requests to change, so it is not for
sure that this is implemented in a new kernel?
I found this as an update to mtdutils.
Does this needs a new kernel to support this functions? I am using a 2.6.33.
Reading this, I think there is no solution for my current system.
Is there a way to show the startaddress of a partition? /proc/mtd
shows just size, not start address.
