Hey, About the second issue - seems the following patch is missing from your tree: http://permalink.gmane.org/gmane.linux.kernel.wireless.general/105449 So the warning is bogus. It will happen if you're working on a single processor (UP) system. To get the latest driver, you can use Luca's tree, which already contains this patch: git://git.kernel.org/pub/scm/linux/kernel/git/luca/wl12xx.git Arik On Mon, Jul 8, 2013 at 9:54 PM, José Miguel Gonçalves <jose.goncalves@xxxxxxx> wrote: > Hi, > > After solving some initial platform issues, I'm now blocked in two more > issues using the wl127x driver with kernel 3.9.9 in a S3C2416 hardware based > platform. > > The first one is that the command "iw wlan0 scan" does not scan all > frequencies.
