This is the document for everyone who needs to write code that runs on the OBC. It will explain how to set up the repo, and how to build, flash, and debug the code.
The repo is this one:
https://github.com/UWOrbital/OBC-firmware
All code that intends to be run on the OBC should be in this repo.
Some terms before we begin:
ARM - the processor architecture of our actual microprocessor that will be on the CubeSat
x86 - the processor architecture of 99% of computers that you are currently using, except the new M1 MacBook pros
Firmware - refers to the final software that will be loaded onto the OBC, with all subsystem code included
Makefile - it is a build system that can record rules on how to compile and build stuff.
Follow the steps listed in the README’s “Getting Started” section.
We currently flashing using the TI uniflash tool.
Since we are using gcc, the associated debugger is gdb the arm-gdb is in the same directory as your gcc compiler
