H96 Max X3 - brcmfmac: brcmf_chip_cores_check: CPU core not detected

Hello everyone,

 

I am not having any luck with the wifi on the H96 Max X3.

I see posts saying the wifi on this box work with meson-sm1-sei610-ethfix.dtb /  meson-sm1-H96max-X3.dtb or h96max-x2-test-bus80-gpu-volt.dtb but they are not working for me.

I did put the BCM4335C0.hcd in /lib/firmware/brcm and the driver apparently loaded.

 

Everything else seems to be working ok. A few posts mentioned it works with kernel 5.6rc1 and 5.7 but I couldn't find those images.

I tried all the images Mr. Balbes have on https://users.armbian.com/balbes150/arm-64/ and I also tried installing the headers.

 

It works fine with Emulec and Android.

 

I see this message below.. (brcmf_chip_cores_check: CPU core not detected) is this the reason wifi is dead?

 

dmesg brcmfmac

If anyone can give me a hint... it would be amazing

Thank you, Leco

When discussing a problem make sure to provide full logs!

Well, I am still on my search for a solution... Thank you all that at least read my post.

 

I wonder what Armbian does next after detecting the wifi chip ID. brcmfmac: F1 signature read @0x18000000=0x16024335

Does it read a configuration file that points it to the right pair of brcmf_sdio_XXXX.bin and brcmf_sdio_XXXX.txt ?

Is there any documentation anywhere about the steps the kernel takes to load the drivers?

I don't understand how the chip id link to the correct driver in /lib/firmware/brcm folder.

 

Thank you community

Leco.
