wpa_supplicant hangs with mwifiex driver and custom hardware
 

So I have embedded linux running mwifiex driver v1.0 (14.57.5.p.41). The driver downloads and initializes then I want to connect to a router using wpa_supplicant and wpa encryption. I have already connected to an open network.
I run
wpa_supplicant -ddd -mlan0 -c/etc/wpa_supplicant.conf
-Dnl80211
the result is:
wpa_supplicant v1.0
random: Trying to read entropy from /dev/random

iface is mlan0

and that is it it just stops - following the code trail it dies in wpa_supplicant/wpa_supplicant.c in
wpa_supplicant_set_driver() - basically an unsupported driver. Any thoughts?

Running wpa_supplicant with no arguments will show you the supported drivers. If the one you want to use doesn't appear in the list, I guess you'll have to recompile wpa_supplicant.

Not that obvious
 

When I run wpa_supplicant with nothing else it shows the nl80211 driver is not loaded. I recompiled with the makefile change to
CONFIG_DRIVER_NL80211=y, unfortunately then I got tons of compile errors. So I have to go back and look at my build. Thanks for your help.
