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 ;-)...

OPOS6UL Dev with NANO.jpg

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 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

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
