mon0 no such device error raspberry pi 4 B #273

Open MaryaRB opened 2 years ago

MaryaRB commented 2 years ago

hello, I've been trying to run nexmon csi on raspberry pi 4 b, I tried to use kernals 5.10, 5.4, and 4.19, and everytime i get the same errors, when using: iw dev wlan0 interface add mon0 type monitor

the error is: command failed: Operation not supported (-95)

and when using: ip link set mon0 up

i get: Cannot find device "mon0"

I never managed to get anything when using nexutil or tcpdump, the output is always zero. does anyone know a solution to this? thank you in advance.

Hints at patched driver not being loaded, but I'm not sure. What does nexutil -k say? I would also check if dmesg mentions "Nexmon".

here are the outputs:

Yup, that's because patched driver module wasn't loaded.

Backup the original brcmfmac.ko supplied with RaspiOS. modinfo brcmfmac -n returns it's location. Then replace it with the brcmfmac.ko file at patches/bcm43455c0/7_45_189/nexmon_csi/brcmfmac_5.10.y-nexmon/brcmfmac.ko - this is the patched driver module.

Repeat that with the brcmfmac43455-sdio.bin at /lib/firmware/brcm/brcmfmac43455-sdio.bin. Replace it with brcmfmac43455-sdio.bin built with Nexmon.

Now run depmod -a, and reboot.

I have an install script that builds Nexmon_csi from scratch and does this here: https://github.com/nexmonster/nexmon_csi/tree/pi-5.10.92. Pre-compiled binaries and scripts for 4.19, 5.4, and 5.10 are here: https://github.com/nexmonster/nexmon_csi_bin

when i try to use modinfo brcmfmac -n i get this error: modinfo: ERROR: Module brcmfmac not found. i tried to use your installing script before but it didn't work because of the same error.

Oh.. Did it never work or did it work for a while and then stopped working?

modinfo: ERROR: Module brcmfmac not found.

Yup, driver module hasn't been loaded.

I'll try to build with my script again this week and see if I can reproduce the error - although I never seem to be able to. Meanwhile, you can use the precompiled binaries: https://github.com/nexmonster/nexmon_csi_bin .

I reinstalled the kernel and used your scrip and it worked, the protocol errors are gone now, however i still get Cannot find device "mon0" when i follow the usage section. I also receive 0 packets when using sudo tcpdump -i wlan0 dst port 5500 -v. I have the Pi connected to network via ether net cable, I tried to use channel 7, 36, and 157 with no luck, any advice?
