I generated an embedded Linux system with Yocto Kirkstone, which has all the required modules for WiFi over an RTL8192 dongle. When I start the device, wpa_supplicant fails connecting the network with the following output
Configuring network interfaces...

But when I manually do
ip link set wlan0 up
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf &
It connects my network and gets the IP with no issue.
What's wrong here ? Thanks !
