Hi!

First, I guess I should mention that this is first time I'm attempting to get wifi going on D4.

I'm getting this:

user@devuan:~/g/ofono$ sudo ifconfig wlan0 down
user@devuan:~/g/ofono$ sudo ifconfig wlan0 up
user@devuan:~/g/ofono$ sudo iwlist wlan0 scan
wlan0     Interface doesn't support scanning.
user@devuan:~/g/ofono$ sudo ifconfig wlan0 down
user@devuan:~/g/ofono$ sudo iwlist wlan0 scan
wlan0     Interface doesn't support scanning.

user@devuan:~/g/ofono$

I'm getting this warning during bootup:

Any ideas?

Try to use iw command. iwlist use an obsolete interface that you need to activate in kernel for back compatibility with old command. Can be your problem?

You have a timeout here. Can be that your reset sequence of the wifi is not optimal because
is not responding?

You may want to add this to Kconfig test... and maybe it would be good to mention iwconfig there, for easier grepping.

I'm using rather old distro; I'll update, but kernel is expected to be back-compatible.. and tested :-).

I tried delays and printks... WL12XX_REG_FUSE_BD_ADDR_1 read fails, and retrying does not really help. If you have idea how to debug/fix this, let me know...
