Hello, here is a patch for flash-kernel to become nand-aware. I also built a package for armhf with this patch that is available from
https://debian.kleine-koenig.org/pool/main/f/flash-kernel/flash-kernel_3.56ukl2_armhf.deb
for testing. On my device (without bad blocks) this works fine.
After talking to some guys in #mtd on OFTC I think this is the right way
to go as upstream won't expand flashcp anytime soon.
Best regards
Uwe
