Hello!
So I have an X96 Max+ (s905x3) TV-box with that mt7661rsn Wifi+BT chip.
Here’s the related udevadm output:
CoreELEC:~ # udevadm info /sys/bus/sdio/devices/*

Stock Android firmware recognizes the chip as mt7663 and has .bin firmware files for mt7663 and mt7668, so I assume they’re all compatible with each other.
Names of the firmware files I found in Android’s /vendor/firmware:
EEPROM_MT7663.bin
EEPROM_MT7668.bin
fw_usb.bin
mt7663_patch_e2_hdr.bin
mt7668_patch_e1_hdr.bin
mt7668_patch_e2_hdr.bin
TxPwrLimit_MT76x8.dat
wifi.cfg
WIFI_RAM_CODE2_SDIO_MT7668.bin
WIFI_RAM_CODE2_USB_MT7668.bin
WIFI_RAM_CODE_MT7663.bin
WIFI_RAM_CODE_MT7668.bin
woble_setting.bin
Btw, I managed to get bluetooth to work somewhat (NOTE: without using the above-listed files), but it was Manjaro Arm with 5.11.13 linux-vim kernel. Not sure if the dtb I was using can be ported to CoreELEC’s kernels, but I’m attaching it anyway as it might help you to help me lol. And yes, it’s a bit messy.
manjaro-dtb.img (46.2 KB)
I also found this on github, and it seems to be some stolen proprietary firmware from mediatek, but since the repo contains no documentation at all, I have no idea what to do with it.
There’s also an OpenWrt package kmod-mt7663-firmware-ap that might be useful, and maybe I’m stupid or blind or whatever, but I failed to find its sources.
So, how do I get that chip working with CoreELEC? Or, even better, with recent 5.x.x kernels?
If you need more info on system/dtb/whatever — just ask for it.
Thanks.
