Re: [Gumstix-users] Pre-built 2.6.33 images available

[Krishna S. <sag...@gm...>]

I tried this pre-built image ( 201004220807 ) on my overo fire +
summit.  And I'm unable to bring up wlan0


root@overo:~# ifconfig -a

root@overo:~# ifup wlan0
Unsupported driver 'marvell'.

Failed to bring up wlan0.

Not sure if I'm doing something wrong!
