Hello,

 

I'm unable to make the RTL8723BS chip on my Tinker Board to work on AP mode with the 5.4 kernel (same configuration works on legacy kernel).  When I try to connect I get this error on dmesg:

 

RTL8723BS: ap recv deauth reason code(3) sta:40:4e:36:cf:8a:18

 

On the console I also get a bunch of kernel errors similar to this:

 

Message from syslogd@localhost at Dec 27 14:26:11 ...
 kernel:[  799.239910] ff60: bf0377a4 dd8057e8 dd07ffac dd07ff78 c014a17c bf0377b0 de2d9128 de2d9128
 

 

Is this a known problem?

 

Thanks

No. This wireless driver is mainstreamed - check who is maintaining it if anyone ... 

At this point not sure if its related, but is is possible that we have some common problem:

@Ravaz

Perhaps this https://github.com/armbian/build/blob/master/patch/kernel/sunxi-current/wifi-8723bs-AP-bugfix.patch is all you need?

Yes,  this seems to be the missing patch.  I will test it upon my return from holidays in one week time.  Thanks a lot for the lightning fast feedback! 

I tried to create a patch for the tinker board following Igor example (see patch below), but the problem persists. Problem must be elsewhere.
