Hi,
I was able to install WPA-2 on my Sitara AM335x linux sdk 5.0. However, recently I downloaded the sitara linux sdk 8.0. Now, I can no longer connect to the wifi. I have tried using this 
but it gives me the following error after root@am37x-evm:/usr/sbin# wpa_supplicant -d -Dnl80211 -c/etc/wpa_supplicant.conf -iwlan0 -B
