Build xtensa llvm from here https://esp32.com/viewtopic.php?t=9226&p=38466

                Create a 16bit R5G6B5 raw image for embedded displays.
              
          
Import your image or create image with GIMP.


Export as bmp -> advanced options -> 16bit


Then to get the raw bytes run tail -c $bytes image.bmp &gt; image.raw where $bytes is w * h * 2 of the image. This removes the BMP header.
