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. I've seen a patch submitted to fix an issue in the driver for
the 5 GHz band
(http://permalink.gmane.org/gmane.linux.kernel.wireless.general/107771) but
this is not my issue, because I can not see also several APs in the 2.4GHz
band after a scan.
The second issue is when I try to associate with an AP using WPA2-PSK with
wpa_supplicant (only able to reach this point by setting "scan_freq" in
wpa_supplicat.conf file to the frequency used by the AP, because of the
inability to perform of a complete scan) I get an error in the driver, as
shown in the log bellow:
[root ~]$ wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
Successfully initialized wpa_supplicant
