Installation

See Chrome OS devices page.

Audio

There are two issues:

  • HDMI codec is not supported;
  • When booting with inserted headphones, pulseaudio does not switch output to headphones and you have to switch it manually. Consider enabling device and booting pmOS with disconnected headphones as stock bootloader may beep at the maximum volume and you will lose your hearing.

Audio issue on rev5

After a certain upgrade (~26.07.2023) you might get your device booted with wrong dtb. To make sure this is the case run cat /proc/device-tree/compatible. The resulting string should contain rev5.

To fix this you need to find your kernel partition and flash /boot/vmlinuz.kpart there. One line command:

$ sudo dd if=/boot/vmlinuz.kpart of=$(findfs PARTLABEL=pmOS_kernel)
