I have a Lantiq Xway Danube Hub based on the 50712 SoC. It is unique in
that it is the only board, afaik, with NOR (512k) and NAND (32MB) on the
ebu. The NOR contains u-boot and configs, the NAND holds the image file.
Having spent several days attempting to adapt
other 50702 devicetree files from Trunk, I need some assistance to move
forward. The NAND is correctly picked up, but erase block checking
fails completely. NOR probing just fails, on kernel 3.3.8 it is picked up by
the JEDEC probe.
I would greatly appreciate your help/advise and will report my results.
TIA, Dermot.
Below my devicetree file and after that the bootlog.
