Tips
Bootstrap
- Put Boot0 jumper to go in Bootstrap mode
U-Boot
- Use OPOS6ULDev "User" LED in U-Boot scripts:
- ON:
BIOS> gpio set 68
- OFF:
BIOS> gpio clear 68
- ON:
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
