Hi,
when upgrading from 2013.05.1 to 2013.06 on an i.MX35 I get the
following log :
- initial log :
barebox 2013.05.1-00001-ga8e8785 #25 Mon Jul 1 17:12:14 CEST 2013

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.
Eric

Are you sure this happens between 2013.05.1 and 2013.06.0? The only
changes in the mtd stuff are:
ae6f751 nand_base: sync flash detection functions with linux 3.9's code
c8af035 Merge branch 'for-next/misc'
7c15fd1 NAND: imx: Fix memory leak
d8ee54f mtd: Nand: Use dev_add_param_bool for erasebad parameter
7c6c61f treewide: Use dev_add_param_int_ro where possible
973176d mtd: update NAND manufacturer names from the kernel
4c2bdc8 nand_base: detect more ONFI flash
So the only patches which seem to change something are from you ;)
Does the 'md' command still work and shows meaningful content in the
NAND?

I think the best way here is using "git-bisect" to find this issue.

I know and I feared I broke something :-( but I don't see where at the
moment.
I'll spend more time on this and provide more details shortly.
