How do I make the pi-topCEED screen work with Android Things

Question

When I try Android Things DP3 with the pi-topCEED, the boot screen isn't displayed properly:

How can I configure Android Things w/ the appropriate display parameter:

• Resolution: 1366x768
• Refresh rate: 60hz

Answer 1

• Mount the sdcard image boot partition

  # on my system
  mount /dev/sdb1 /mnt/disk
  

• Append the following value to config.txt

  # Define new custom HDMI mode <width> <height> <refresh_rate>
  hdmi_cvt 1366 768 60
  # Select HDMI DMT mode (computer screen)
  hdmi_group=2
  # Select custom mode defined earlier
  hdmi_mode=87
  

• Unmount and eject your sdcard

  umount /dev/disk
  sync
