NanoPC T6: MT7925 (WiFi7) cannot load firmware

[Robert Gonciarz]

The issue is related with FriendlyElec NanoPC T6 LTS (platinum support) but there were no separate category.
The SoC was merged to mainstream kernel in 6.7 version. It is properly recognized and a module is loaded but there is an issue with loading a firmware:

It seems a package is missing.

After downloading firmware from:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek/mt7925/lib/firmware/mediatek/mt792592a427346d5288ca9c974820c43cadc7

md5sums:

92a427346d5288ca9c974820c43cadc7  BT_RAM_CODE_MT7925_1_1_hdr.bin
ebd4fd8a633e0692b9189cf544be5c40  WIFI_MT7925_PATCH_MCU_1_1_hdr.bin
161aff211a93048db1720f6c11b1529b  WIFI_RAM_CODE_MT7925_1_1.bin

And moving them to directory:

/lib/firmware/mediatek/mt7925

Everything works fine.

I created an ubuntu package. You may include it to armbian distro:
sudo add-apt-repository ppa:gonciarz/firmware-mt7925

There is an armbian-firmware package. I suggest to push your adjustments there: https://github.com/armbian/firmware/
