Building the OBC firmware

The following is a simple guide on building the app for the OBC.

1. Before compiling, ensure that the Python virtual environment is activated. If you do not have this configured, see Initial setup.

2. From the root directory, run the following commands:

   mkdir -p build_arm && cd build_arm
   cmake .. -DCMAKE_BUILD_TYPE=OBC
   cmake --build .

   Tip: Reducing build time

   The cmake --build . takes some time to run since it is using a single thread to compile. To speed up the process we can replace it with one of the following commands:

   1. make -j 16 (Recommended for most systems)
   2. make -j 32 (This is faster but depends on if your system can handle 32 parallel jobs)

3. There are also plenty of extra options that you can use besides -DCMAKE_BUILD_TYPE by appending them to the cmake .. command. Take a look at the CMake options guide.

   Caution

   Make sure to specify the -DBOARD_TYPE= option to avoid any unwanted behaviour.
