Description
The Armadeus System's standard development board/baseboard for the OPOS6UL module, the OPOS6ULDev, can also be used to evaluate OPOS6UL_NANO SoM. For this you will require a SODIMM adapter... and accept some limitations due to the lack of GPIOs on OPOS6UL_NANO modules, compared to OPOS6UL

Errata
- On OPOS6UL_Dev boards with hardware revision <= 1.1, the USB ports won't be powered unless you do an hardware modification. This modification consist of forcing to 3.3V, the 2 signals USB_OTG1_PWR & USB_OTG2_PWR on U3/AP2152 chip.

Tested RPi shields/hats
- Dragino Lora/GPS HAT... TO BE RETESTED !!!!
Tips
Bootstrap
- Bootstrap jumpers are not connected to OPOS6UL_NANO and so not useful with this SoM
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
