wifi on Motorola Droid 4 in 5.3-rc2

[-- Attachment #1.1: Type: text/plain, Size: 1227 bytes --]

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:

[   13.733703] asoc-audio-graph-card soundcard: No GPIO consumer pa

[   14.279724] wlcore: WARNING Detected unconfigured mac address in

Any ideas?

Best regards,

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?

Let me see ... CONFIG_CFG80211_WEXT was not set.

Tried enabling it, and now I got. I remember getting it before,
too... let me try few more boots, perhaps it is random.

Two more reboots (with no changes in the config) and wifi now
works. Thanks!

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

This is ok. It means that your nvs file is not the original one taken

you can use plt command with calibrate

From developers' point of view WEXT is ancient and untested, everybody
should switch to nl80211. So I strongly using iw (which uses nl80211).
Of course this nothing to do with the wlcore warning you saw, just
wanted to make you aware the state of wireless extensions.

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...
