problem seems that rfkill sets also CONFIG_CFG80211 to m, if this is set back to y no linking-error occours (rfkill+bt alone does not change that).

btw. i’ve tried to kick off wmt-tools here:
currently hang on missing dts-nodes on loading driver
can you point me some instructions how to run AP on Ubuntu 18.04.1 on your 4.14.66 kernel
I compiled your kernel with ath10k drivers (my 2nd wlan card is Sparklan WPEA-352ACN based on Qualcomm Atheros QCA9880-BR4A chipset).
I also put linux-firmware (for ath10k) to /lib/firmware.
I would like to run 802.11AC on Atheros at 5GHz as main network and build in wlan card at 2.4GHz as IOT network (the second is not so important now I have working AP based on BPi Pi Pro).
Thanks as always for any help.
First you have to look if your new wifi-card is recognized (lsusb/lspci+ip a).
Then look in my wiki for ap-configuration (need own hostapd.conf for each wifi).

seems internal is not recognized …
your tutorial is that: http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:wlan ???
Internal device have to be created using wmt-tools. See wifi.sh on my github (utils/scripts).
External seems to be ok so far…
I tried your tutorial, put appropriate files (change them chmod +x) and run wifi.sh:
root@serwer:~# ./wifi.sh
wifidev does not exist...create it...
./wifi.sh: line 46: 401 Segmentation fault /usr/bin/wmt_loader > /var/log/wmtloader.log
./wifi.sh: line 41: /usr/bin/stp_uart_launcher: Permission denied
Error, wifi device no created, /dev/wmtWifi
Device "ap0" does not exist.
Error, device no available, ap0
/var/log/wmtloader.log is empty file …
and my firmware is in /lib/firmware not /etc/firmware (corrected that in wifi.sh
Wifi.sh starts only internal wifi…you find wmt-tools and files (firmware/config) on my gdrive…simply unpack that archive in your rootfs (same folders!)
https://drive.google.com/open?id=1E3RKyf-P2ixrJykj2548y0r67JY2u5vj
Thanks,
wifi works, SSID is visible but I cannot connect (even don’t ask me for password). I edited wifi.sh and put my ssid and password.
Can I copy wifi.sh to wifi2.sh and change apropriate values (ssid, ap0 to ap1) to run external wifi card?
Ssid and password in wifi.sh?
These values are in /etc/hostapd/hostapd_ap0.conf
You have to configure also dnsmasq and ip in wifi.sh
For second hostapd create a secont hostapd.conf and only run hostapd with this config
I start a second bash-script at the end of wifi.sh
[13:59] frank@bpi-r2-e:~$ cat /usr/local/sbin/hostapd_2.sh
#!/bin/bash
pid=$(ps auxf | grep hostapd | grep wlan1 | awk '{print $2}')
if [[ -n "$pid" ]];then
kill -9 $pid
fi
sleep 5s
hostapd -dd /etc/hostapd/hostapd_wlan1.conf &>/var/log/hostapd_wlan1.log &you’re right, a made changes in hostapd_ap0.conf and created new hostapd_ap1.conf for external
Before adding second script to wifi.sh test it…
Based on your configuration you have to use different subnet for new wifi…ip and dhcp
is ap0 working now (connection and dhcp/access from client to server)?
Anyone having an idea how we can drop wmt_loader and stp_uart_launcher?
Maybe it’s a good idea to make wifi also to an module so that kernel itself is completely loaded when wifi-driver is initialized
hi, i’m trying to port wifi-driver to 5.3
compile/bootup works well, but i cannot write to /dev/wmtWifi
root@bpi-r2-ubuntu:~# echo A >/dev/wmtWifi
-bash: echo: write error: Input/output error
root@bpi-r2-ubuntu:~# ls -l /dev/wmtWifi
crw------- 1 root root 155, 0 Jul 24 11:11 /dev/wmtWifi
any idea how to fix this? commands before (wmtloader,stp_uart_launcher) were without errors.

so something near mtk_wcn_wlan_gen2_init seems to go wrong
after
do_wlan_drv_init:WMT-WIFI char dev init, ret:0
mtk_wcn_wlan_gen2_init only calls initWlan which calls createWirelessDevice which calls wiphy_register,where crash occours
warning itself points to
wiphy-register is called here:
i found no position where vendor_commands[i].policy is set…maybe this is the problem

seems i need to change this struct same way it’s done in the commit for other drivers:
Currently patches out the warn-on and wifi works…have contacted author of this change to help me fixing this the right way…

i think i have fixed the problem…can now start wifi with WARN_ON activated
Hi all,
wow quite some content in this thread.
So what’s the current best way of doing wifi drivers for BPI-R2 with @frank-w 4.14-main branch? Do we still need the blobs with wmt_loader etc.?
Also: dId anyone find a way yet to make those go nicely with OpenWRT?
/asac
We still need wmt-tools cause i did not find a way to drop these and did not get any help on this yet.
@abbradar have tried pushing it to openwrt but it is too big and dirty to get it upstream (same for linux mainline)
ok thanks i will try the old blobs I used in the past and recombine them with your 4.14 branch then and see how that flies these days the openwrt userspace i currently use …
My repo and packages (tar.gz and deb) also containing the wmt-tools
I’ve updated my openwrt fork in https://github.com/abbradar/openwrt/tree/bpi-wifi , this required changes to wifi drivers code, see https://github.com/abbradar/mt6625l-wlan-gen2/commit/5a8fafb8b3d99da21d356219ed599556efbd990b . I’m also trying to upstream some patches again, see https://github.com/openwrt/openwrt/pull/2365
