That's good.

That's not :-(

That's a consequence of the failure above.

Does this happen on all devices or only on some of them ?

Hmm, that's an odd problem. First, can you please check that you're
indeed flashing the environment, i.e., that the file name and the
device name you're passing to nandwrite are indeed correct ? The
output of your script run with -x could be useful for checking this.
(Change the #/bin/sh to #/bin/sh -x)

If this doesn't help to solve the problem, could you please send me
the following information (in private mail, due to the various
binary attachments) ?


- the script output, as described above
- printenv from u-boot
- cat /proc/mtd from Linux
- the environment image you're trying to flash
- env_linux.bin, created with
  nanddump -b -o -f env_linux.bin /dev/mtd2
  after flashing the environment from Linux
- env_dfu.bin, created with
  nanddump -b -o -f env_dfu.bin /dev/mtd2
  after flashing the environment with DFU

Thanks !
