Welcome to the RoboJackets IGVC firmware repo!

Dependencies

• Updated arm-none-eabi-gcc
• protobuf-compiler
• python-protobuf

The second two can be installed with

sudo apt install -y protobuf-compiler python-protobuf

For more details, check the Dockerfile.

Updating arm-none-eabi-gcc

For some reason, it seems like the version of arm-none-eabi-ld on Ubuntu 18.04 has some linking problems. The problem seems to go away on newer versions of arm-non-eabi-gcc though.

Steps to update arm-none-eabi-gcc:

1. Download gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2
2. Untar it and move it to some location (eg. /opt/gcc-arm-none-eabi-8-2018-q4-major)
3. Add it to your $PATH variable, eg. add the following line to .bashrc:

   export PATH="/opt/gcc-arm-none-eabi-8-2018-q4-major/bin:$PATH"

This should solve the ld issues

Building Documentation

Make sure to git submodule init && git submodule update as the repo uses git submodules for the mbed-os and nanopb dependencies.

mkdir build
cmake ..
make

There should be a igvc-firmware.bin file that was compiled. Drag that onto the mbed to flash the firmware.
