NR500EA "c0 cnss: wlan en pin is not supported"

WIFI/BT

Hi.
My Wifi just don’t work anymore for no reason. One time before It just freeze and them I reboot and it’s gone. I tried with reset multiple times. I check “dmesg” and found this errors:

[   50.865433] c0 quec_wlan.init (3501): drop_caches: 3
[   51.106641] c0 NET: Registered protocol family 27
[   51.107986] c0 [enable_bb_ctxt] 0x1000

[   51.108336] c0 cnss: wlan en pin is not supported
[   51.108339] c0 cnss: wlan en pin is not supported

I check the command “lspci” and NO Device is found. Before this was the devices:

01:00.0 Class 0280: 17cb:1103
00:00.0 Class 0604: 16c3:abcd

I think it has to do with PCIe or WIFI (wlan-en-gpio). Ethernet works, although there’s less interfaces in “ifconfig” most sipa and vpcie gone. This is actual lsmod.

root@udx710-module:/# lsmod

It seems is something that has to do with PCIe (cnss) and WIFI (wlan-en-gpio). Any help I appreciate thanks in advance.

Sorry for late replay.
Could you provide the complete dmesg log.

Please try
find / -name “wlan.ko”
It seems that the dirver for FC06E is not on the device.

No problem. Thank you for time and support. I can only get Dmesg log from Ethernet not fully complete but is attached. DMESG_UTF8.txt (51.2 KB)

It means that it is recognized. The driver should be wlan.ko and wlan_cnss_core_pcie.ko.
Please search it on the device.

I can see the
[ 47.443440] c1 wlan_cnss_core_pcie: loading out-of-tree module taints kernel.
Please check

lsmod | grep wlan
find /  -name "wlan.ko"

The error refered is in quec_wlan.init file. So I did this…
Looking the file content and line errors:

root@udx710-module:/# cat etc/init.d/quec_wlan.init

Result: QUEC_WLAN_INIT.txt (8.6 KB)

running this file it outputs:

the “wlan” depends “wlan_cnss_core_pcie” it should be loaded 1st, I can see in do_ftm_start() from quec_wlan.init but this is the result:

I am sorry I am not familar with the RG500U.
From the log it seems that the wlan_cnss_core_pcie already installed.
So please check
lsmod | grep wlan
make sure that both wlan_cnss_core_pcie.ko and wlan.ko have loaded.
Just check maybe you do not need the quec_wlan.init. We can just load the kernel on ourself.

I will try to find a RG500U and test it.
