Tested RPi shields/hats

Tips

Bootstrap

U-Boot

  • Use OPOS93Dev "User" LED in U-Boot scripts:
    • ON: 
       BIOS> gpio set 68
    • OFF: 
       BIOS> gpio clear 68

Linux

  • to activate login in Framebuffer console, please uncomment /etc/inittab line 35 this way:
# Set up a getty on LCD
tty1::respawn:/sbin/getty 38400 tty1
