Booting Linux or Android, you observe a message like: Ganges-SDIO WLAN: probe of mmc0:fffd:1 failed with error 1 and you notice WiFi does not work

Booting Linux or Android, you observe a message like:
Ganges-SDIO WLAN: probe of mmc0:fffd:1 failed with error 1
and you notice WiFi does not work.

During manufacturing test, Digi operations switches driver to RF evaluation mode.
On some batches Digi missed to switch back to normal mode, which is causing the Linux WLAN drivers not to work.

To fix the problem set U-Boot environment variable wdmode=1:
# setenv wdmode 1; saveenv
or erase this variable:
# setenv wdmode; saveenv

next time you boot, the WLAN should work.
