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. Consider this usage as temporary, until OPOS6UL_NANO get the development board it deserves... Don't hesitate to do some lobby to Armadeus Systems hardware team ;-)...

Errata

On OPOS6UL_Dev boards with hardware revision <= 1.2, 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.

Feature list

Note:

You can't use CAN interfaces of OPOS6ULDev. CAN buses might be output on LCD connector but will require an additional PHY.
2nd Ethernet port is not available.
You won't see anything on LCD unless you force LCD Backlight pin to Logic 1.
RPi connector connected buses are different of the ones when using an OPOS6UL SOM.

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 3 
```
- OFF:
```
 BIOS> gpio clear 3 
```

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
