iMX nand BBT problem

[Eric Bénard]

Hi,

when upgrading from 2013.05.1 to 2013.06 on an i.MX35 I get the
following log :

- initial log :

envfs: wrong magic on /dev/env0
no valid environment found on /dev/env0. Using default environment
running /env/bin/init...
no MAC address set for eth0. please enter the one found on your board:
00:12:34:56:78:90 saving environment

Once I reset the board I can see that the env was not saved and I get
prompted again for the MAC address.

Any idea of what can be wrong there ?

This board is configured in external boot from a 2k NAND (and was
already using flash BBT), and the kernel and rootfs still run without
any visible problem.
