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.
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-utilson your host, not the Rpi with debug HAT. x86-hostedwishbone-utilsis 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 pexpectpip3 install psutil-- for the scriptminder.py routineraspi-config-- enable serial port (and disable login shell on it), SPI, I2C.
