Bootstrap Mainboard

A collection of scripts to bootstrap a factory-new or bricked Precursor.

Also includes factory test scripts, to be run on the factory test jig.

Dependencies

These scripts are assumed to be run on a Raspberry Pi with a RaspiOS "buster" image (initially tested against Jan 11 2021 release on a Pi 3B+). Compatibility is not guaranteed for a Pi 4, but it "should" work.

Most of the dependencies are cloned in as submodules, but for select applications you may want to install more:

  • GDB debugging and USB updates: wishbone-utils. Requires Rust to build, but you should also be able to get the pre-built Releases to work for GDB debugging (but not USB updates). Note: you can also plug the USB-C port directly into your host, in which case you would need the wishbone-utils on your host, not the Rpi with debug HAT. x86-hosted wishbone-utils is actually the more typical use case.
  • Factory test:
    • pip3 install luma.oled -- Luma OLED. Generally, you don't want to run the factory test, as you don't have the rather expensive accompanying PCB with all the sensors and adapters to make it work.
    • pip3 install pexpect
    • pip3 install psutil -- for the scriptminder.py routine
    • raspi-config -- enable serial port (and disable login shell on it), SPI, I2C.
