This is the Mainline stable kernel 5.3.1 for BananaPi M2 Zero with the following working:

  • HDMI
  • sound
  • Bluetooth
  • cedrus
  • wifi
  • eth

The instructions below are for the Kernel 5.3.1 upgrade from a previous kernel, if you already have kernel 5.3.1 running you must downgrade before you proceed.

Instructions

  • make a backup of your SD CARD

  • Update the firmware for the Bluetooth to work

      sudo tar -xvpzf firmware-v3.tar.gz -C /lib/firmware --numeric-ow

  • Update the Kernel

      sudo dpkg -i linux-image-5.3.1_1.0-31.deb

Before you update

If you already have the kernel 5.3.1 running that had HDMI and BT broken you must downgrade before you run dpkg -i or it will display you are already at 5.3.1.
