wireless driver crashing in raspbian lite

[Ravin Goyal]

Hello, I have a banana pi m2+ running raspbian lite 3.4.112-sun8i
I am running hostapd on it.

My wireless chip is AP6212 ,when I start hostapd sometime it runs
sometime it leads to kernel crash.

please follow this link to see the kernel messages: https://clbin.com/PXBSB?hl

To make hostapd work properly I have to manuallly run this command

modprobe -v bcmdhd op_mode=2

bcmdhd is my wireless driver

after this hostapd is able to broadcast the ssid, if i don't provide
the op_mode=2 while loading the module, hostapd will not broadcast the
ssid.

Following link: http://linux-sunxi.org/Wifi shows no particular driver for AP6212 in the list.

Any help appreciated ?

Ravin
