I have tested with 1PJ now, even using kernel 5.8.9. "iw list" shows a lot 
of information, but "wlan0" is down and it is not possible to bring it up:

Any ideas?


I have used firmware from 
https://github.com/kvalo/ath10k-firmware/tree/master/QCA9377/hw1.0/untested

I have also been provided with these files (which I suppose are designed 
for qcacld):

1PJ-bdwlan30-20190527.bin
rampatch_tlv_tf_1.1.tlv
silicon_QDART-1PJ_20190527.bin

Does that help?

Best regards,
