Mt7615 wifi driver testing

Hi,

Ryder Lee wrote a mt7615-driver and i have it integrated into my 4.19-branches for testing.

R64: https://github.com/frank-w/BPI-R2-4.14/tree/4.19-r64-main (binary-package on github-releases)

• tested till wlan0-device is visible and readable via “iw”

R2: https://github.com/frank-w/BPI-R2-4.14/tree/4.19-mt7615 (binary-package on my gdrive…

• currently untested

you’ll find firmware on github in utils/firmware which needs to be copied to BPI-ROOT/lib/firmware (+reboot)

for 5g-testing here are the steps to do additionally to 2.4ghz: BPI-R64 Kernel-Development

i currently can test only on r64 (pcie-card) because my card is too large for r2 (bend over coils next to pcie-slot) and i have mt7612 mounted on it for testing 4.19 driver (openwrts mt76 is currently broken for this chip)

debian stretch-images (without this specific kernel) for r2/r64 are also on my gdrive

1 part i see is missing mac-address on wifi-device (00:00:00:00:00:00)

added this to my /etc/network/interfaces followed by “service networking restart”

auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
  pre-up ip link set $IFACE address 02:01:02:03:04:08 up
  address 192.168.18.1
  netmask 255.255.255.0

currently i hang on bring wlan0 up:
