MXQ Pro+ 4K: S905 2G/16G (with AP6330 Wireless)

[wdp]

Hi

 

I have TV box as per the subject (MX170 board with no reset switch to be more specific).

 

Wrote this image (on SD Card): Armbian_19.11.3_Aml-g12_bionic_legacy_5.3.0_desktop_20191126.img.xz

 

Using this DTB file (updated file name in uEnv.ini): meson-gxbb-vega-s95-meta.dtb (tried all other meson-gxbb-*.dtb files without success)

 

Able to boot and so far everything (including LAN) seems to be working, except wi-fi.

 

The module appears to load, but wireless card does not scan networks or connect to other networks.

 

Extract from dmesg:

I have searched for 2 days for a solution, but unable to resolve this. I don't have enough experience / knowledge to know where to go from here - is it a problem with the DTB file or do I need to look at firmware for the wireless card? 

 

Any advice/suggestions would be much appreciated?

 

Thanks.

I think you are lucky. The firmware blob is already there (you can see the version: 5.90.125.104), but you need the txt file which is also called the NVRAM.

You just need to try to copy /lib/firmware/brcmfmac-ap6330-sdio.txt into /lib/firmware/brcm/brcmfmac4330-sdio.tronsmart,vega-s95-meta.txt and reload the brcmfmac module (or just reboot the machine).

 

If that one does not work or work badly, you may try to copy /lib/firmware/brcmfmac-ap6330-sdio.bin over /lib/firmware/brcmfmac4330-sdio.bin to replace the binary blob too with a blob very specific for ap6330, which may work better and enable 802.11a frequencies too.
