NAND flash not working with Debian Wheezy 3.4.85

Submitted by cjs94 on Sat, 04/30/2016 - 22:45

Hi,

I've just installed the Wheezy image from Ledato for the nanosg20 and have found that the flash does not work after booting. I can see the MTD partitions in dmesg, but cat /proc/mtd shows nothing, there are no /dev entries and the UBI tools fail. Has anyone else seen this? The standard Lenny image works fine.

Thanks,
Chris

There is indeed a small error in the Linux image resulting in this problem. I uploaded an updated Linux image debian package that you can install with dpkg. After a reboot, the problem should be fixed:

Thank you, but could you please share the updated Nanos patch, so that I can build from source?

Thanks,
Chris
