I would like to know if I have in my folder /lib/firmware/ the firmware to use correctly a wifi driver.

The general problem is:

root@bananapim2plus:/home/guillaume# ifconfig wlan0 up

SIOCSIFFLAGS: Operation not permitted

I suspect the firmware is not correctly loaded.

So, I don't know if it's possible to know what is the firmware needs the driver bcmdhd.

Some informations with this driver loaded:

# iwlist wlan0 scan

wlan0     Interface doesn't support scanning.

The chip is AP6212, with inside wifi&BT.

The wifi chip is a Broadcom BCM43438
