Page fault on branch NEW_ATHP_ARVIF_LOCK

[leobalbi]

Hello folks,

As requested by Geramy I'm opening a new issue.

I'm with a dell xps 9380 with the some problem here (under FreeBSD 12.0 release):

I'm using the ARVIF_LOCK brach;

root@Radagast:/home/lbalbi/Src/athp/athp # git branch

NEW_ATHP_ARVIF_LOCK

And tried all firmwares from : https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0

Do I'm making something wrong, or missing something?

I can test any code you wish, if this help.

I've put the core.txt at https://drive.google.com/drive/folders/12m3JDlMCeK-YYgNQeaJTK6dp2D_ytMgQ?usp=sharing.

Thank's in advanced

Best's

Hi!

I have the same issue as yours.
Did you successfully solved this issue @leobalbi? Thanks a lot!

[Geramy]

Hey guys have you tried my firmware file I gave to the other guy on the other thread? This was not provided by this repository it was a google share link, @leobalbi

[Geramy]

So the problem is that it cannot load that firmware file, you must have the wrong firmware in there. Everything has to be the right version otherwise it wont attach the correct methods to the correct firmware file methods and it will crash like it did, Please try my firmware file for QCA6174 0x32, its in Bug number #20
