dtoverlay=rpi-sense
Adafruit PiTFT Plus (3.5 inch Resistive Touch screen)
Remove the symlink for the dtb:
rm /boot/efi/dtb
Edit the '/boot/efi/config.txt' to add the overlay
dtparam=i2c_arm=on dtparam=spi=on dtoverlay=pitft35-resistive hdmi_force_hotplug=1
Add to the kernel parameters
fbcon=map:10 fbcon=font:ProFont6x11
Due to a bug the kernel module will not load automatically. On boot the module can be loaded with:
modprobe hx8357d
To workaround the bug and have it load automatically use:
echo hx8357d >> /etc/modules-load.d/hx8357d.conf
