  • generate overlay : sudo make rpi_overlay
  • add modules tinydrm and it8951 in /etc/modules
  • add a line "dtoverlay=it8951" in /boot/config.txt
  • add "fbcon=map:1 vt.color=0xf0" at the end of /boot/cmdline.txt
  • to disable cursor blinking, add a line "echo 0 > /sys/class/graphics/fbcon/cursor_blink" in /etc/rc.local

Beaglebone

  • generate overlay: sudo make bb_spi0_overlay
  • sudo cp IT8951-00A0.dtbo /lib/firmware/
  • edit /boot/uEnv.txt to add dtb : dtb_overlay=/lib/firmware/IT8951-00A0.dtbo - add "vt.color=0xf0" at the end of cmdline= in /boot/uEnv.txt
