The steps needed for the console were:
- Download the customized OS image for this display from Adafruit. 2015-02-16-raspbian-pitft22_150312.zip
- burn that image to some sdcard and copy the /boot/overlays/pitft22-overlay.dtb into the /boot/overlays/ folder of the arch linux sdcard.
- Edit /boot/config.txt to include:$this->bbcode_second_pass_code('', 'device_tree_param=i2c_arm=on
device_tree_param=i2c_vc=on
device_tree_param=spi=on
dtoverlay=pitft22,rotate=270,speed=32000000,fps=20') - Edit /boot/cmdline.txt and insert this code after "rootwait"$this->bbcode_second_pass_code('', 'fbcon=map:10 fbcon=font:VGA8x8')
- reboot
