flight core v2 compilation

@hockey_fan Is there a specific reason you're building the flight core firmware yourself and not loading one of our prebuilt binaries?

Since those instructions are out of date, following them will produce an out of date binary.

The newest pre-built binary is: http://voxl-packages.modalai.com/dists/fc-v2/staging/modalai_fc-v2_1.14.0-2.0.85.px4

@tom I need to make modifications to the code, that's why I want to build it.

[hockey_fan]

I'm using the flight core v2 standalone board as a development platform with PX4 before moving on to the voxl2 board environment.

@hockey_fan Understood, I recommend doing your development off the tip of our branch instead of modalai-1.13.3:

GitHub - modalai/px4-firmware at voxl-dev

PX4 Autopilot Software. Contribute to modalai/px4-firmware development by creating an account on GitHub.

GitHub (github.com)

@tom Shall I use the .yml file mentioned at the first comment to build flight core v2, or is there a dockerfile in the repository that will work?

[hockey_fan]

I am still very confused on how I should build for flight core v2, and which docker file to use. Which is the git repository needed to get to the ci tools? It is not included in the regular voxl-dev repository.

@hockey_fan I recommend installing voxl-docker on your host machine, this will guide you through installing docker and the voxl-docker repo which makes building voxl packages easier.: https://docs.modalai.com/voxl-docker-and-cross-installation/#how-to-setup-voxl-docker-and-voxl-cross

Once done, you'll be able to do the following:

move into the px4-firmware directory

cd px4-firmware

Mount the directory into the docker container (the first time you run this it will download the px4-dev-nuttx-focal docker image to your host machine

voxl-docker -i px4io/px4-dev-nuttx-focal:2022-08-12

Once in the container:

make modalai_fc-v2

This will generate the px4 build at px4-firmware/build/modalai_fc-v2_default/modalai_fc-v2_*.px4 which can be accessed inside or outside of the container

@tom Thanks very much, I got it working, appreciate it.

@hockey_fan No problem, I'll update the docs page with this info, thank you for pointing this out
