imx7 hostapd headache

Hi,

I'm using an imx7sabresd with Yocto 4.1.15 ( Jethro ) with the hostapd package version 2.4 and despite many hours it's still not showing up as an access-point. I've followed many set-ups but still no AP, the AP "looks" like its trying to work.

A few strange things: 1 - all the documentation and web forums speak of /etc/hostapd/hostapd.conf and etc/default/hostapd my Yocto build has neither directory only /etc/hostapd.conf.

I have confirmed and tested wlan0 and can do an 'iw' scan for other APs etc, When hostapd runs I get the following output:

root@imx7dsabresd:~# hostapd /etc/hostapd.conf
Configuration file: /etc/hostapd.conf

device role select failed

wlan0: AP-ENABLED

The only this that looks possibly wrong is: device role select failed. According to forums I do the following:

"...find the line #DAEMON_CONF="" and replace it with DAEMON_CONF="/etc/hostapd/hostapd.conf"

Again no such directory on my imx7 ( only /etc/hostapd.conf )

Some help on this would greatly be appreciated!!

BR,

Ed.

Fix was simple yet hard to find. For others:

Stop hostapd then "echo 2 > /sys/module/bcmdhd/parameters/op_mode". This will set the driver mode to AP mode and "device role select failed" will disappear when next starting hostapd. Restart hostapd.
