SYSTART - Oxalis

This guide will take you through all the steps from unboxing your kit to getting to a working U-Boot console on the Oxalis.

What you need

Your kit should include the following:

  • Oxalis Board
  • LS1012A SOM mounted onto the Oxalis
  • A plug fitting the 12V power jack on the board, in case you need to fashion a power supply cable

To complete this guide you'll also need:

  • 12V 2A DC power supply
  • Micro-USB cable
  • A Windows, Linux or Mac computer loaded with your favorite terminal software for your system
    • See Appendix A for information on terminal programs for your system
  • 5 minutes

Mix and stirr...

  1. Connect your computer to the Micro-USB port (X1) of the Oxalis via the Micro-USB cable.
  2. Fire up that terminal software on your computer and select the new port that Oxalis just has shown up as
  • Baud rate: 115200
  • 8-N-1:
    • 8 data bits
    • no parity
    • 1 stop bit
  1. Without connecting the Oxalis, power up your 12V power source.

Apply heat...

  1. Connect the Oxalis to 12V power and watch the Oxalis Status LEDs turn on
  2. You should see the Oxalis going through it's boot process, which finishes with a "=>"

The full boot log looks something like this:

Congratulations! You are running U-Boot now.

Appendix A: Terminal software

SparkFun has a rather comprehensive tutorial on terminal software for Windows, Mac and Linux.

It is long though, if you want our short and sweet information, read on.

Recommendations in short:

  • Windows: putty (for example: putty.exe -serial com# -sercfg 19200,8,n,1,N )
  • MacOS: screen (for example: screen /dev/cu.usbserial-XXXXX 115200 -L )
  • Linux: screen (for example: screen /dev/ttyACM0 115200 )

Windows: putty

Linux: screen

MacOs: screen
