Solder across Adafruit 2.4" TFT Breakout IM1/IM2/IM3 jumpers:
-
Solder the two (2) JST SH 6 Wire Assemblies to the Adafruit 2.4" TFT Breakout with:
JST Pin TFT Pin 1-1 GND 1-2 Vin 1-3 MOSI 1-4 MISO 1-5 CLK 1-6 CS 2-3 D/C 2-4 RST -
Connect JST-1 to S1.1 connector on BeagleBone Blue.
-
Connect JST-2 to GP0 connector on BeagleBone Blue.
-
Boot BeagleBone Blue using 2016-11-06 or newer image from https://beagleboard.org/latest-images.
-
Run the blue_adafruit24_setup.sh script below to create /dev/fb0.
-
See any of the many tutorials on using a raw framebuffer (/dev/fb0) in Linux. As an example, I did 'cat /dev/random > /dev/fb0':
