uts-enable

Test project trying to enable GPIO pins for UTS Matilda payload on WS-1 cubesat.

Cross-compiling for BeagleBone

This project is set up to compile for Mac and for the Beaglebone Black (BBB). To build the code for all supported platforms, just run cargo build.

This will fail until you have correctly set up the cross-compiler for the BBB.

If you want to build just for your current platform, pass the platform "triple" as the target for cargo. For example, on Mac:

$ cargo build --target aarch64-apple-darwin

You can also edit the default target platforms in .cargo/config.toml.

On Mac

To set up cross-compiling for BBB:

• Add the target for your Rust environment with: rustup target add arm-unknown-linux-gnueabihf
• Install the ARM Linux cross-compiler arm-unknown-linux-gnueabihf from osx-arm-linux-toolchains, and symlink the bin/arm-unknown-linux-gnueabihf-gcc command to your PATH as arm-linux-gcc. (It needs to match the linker configuration in .cargo/config.toml.)
• Install the BBB toolchain from Cube-OS toolchains, and add its absolute path to the BBB_TOOLCHAIN in your environment. (The relevant library path is added for the linker by build.rs, which will fail if something is wrong here.)

On Linux

• Add the target for your Rust environment with: rustup target add arm-unknown-linux-gnueabihf
• Install the BBB toolchain from Cube-OS toolchains, and add its absolute path to the BBB_TOOLCHAIN in your environment. (The relevant library path is added for the linker by build.rs, which will fail if something is wrong here.)
• Either add $BBB_TOOLCHAIN/usr/bin/ to your PATH, or symlink $BBB_TOOLCHAIN/usr/bin/arm-linux-gcc to a directory on your PATH, like ~/bin. This will be used as the linker, as configured in .cargo/config.toml.

With Docker

The CUAVA team have provided a Docker configuration which can be used for compiling for both the satellite primary computer and the payload computer.

You can get it from Cube-OS/cubeos-dev.

To get it working on Mac, you need to:

• Edit the dockerfile to disable the 32-bit library installation
• Build the image: docker build -t cubeos-dev .
• Connect your SSH agent when starting the container like this:

docker run -it -v "$PWD":/usr/cubeos \
    -v /run/host-services/ssh-auth.sock:/run/host-services/ssh-auth.sock:ro \
    -e SSH_AUTH_SOCK="/run/host-services/ssh-auth.sock" \
    -w /usr/cubeos cubeos-dev bash
