Mainboard testing procedures - Geowissenschaften/EXCISS GitHub Wiki

Introduction

A full mainboard testing requires a multistep procedure for each major components. Each testing procedures contains preparations and the actual testing procedures. Also, a special testing software are required for each testing procedures.

Test procedures

MCU gpio and power path testing

Preparations

Remove the following components:

  • all microSD card for the SCU
  • PSU unit
  • Science unit (ignition and HV-unit)

Optional:

  • front and backlights
  • USB mass-storages

MCU Prep

Required Arduino IDE test application:

I2C MUX and I2C device test.

Preparations

The PSU is not required, but since the communication with the PSU requires i2c a test with PSU should be done before executing the PSU testing procedures.

MCU Prep

Required Arduino IDE test application:

One-wire temperature sensor test.

Preparations

Flash Arduino code. Open serial terminal with 9600baud setting. A regular readout is shown down below:

Required Arduino IDE test application: Arduino test application

SCU Shutdown test

Preparations

Unplug frame USB connection.

First remove any SD mass storages.

Insert USB mass storages.

Flash MCU with test code.

Put a SD mass storage with SCU OS with shutdown script in SD card slot XU1100.

Connect debug serial and open a serial terminal with 9600baud.

Plug frame USB connection for powering the mainboard.

Check for successful SCU boot up.

Unplug frame USB connection. Serial terminal shows "start shutdown". Also a counter is shown every second until complete power down.
