dimtass / openchronos-ng-elf

Fully modular opensource firmware for the eZ430 chronos using TI's new msp430-elf-gcc

CMake template for TI eZ430 Chronos

This repo is a fork from here.

The reason I've forked the repo is that it wasn't working for me and therefore needed to update some parts in order to be able to built using cmake. I've also created a docker image that contains the msp430-gcc-9.2.0.50_linux64 toolchain using packer and Ansible.

There is already some documentation in the original repo, but there are a few things that are deprecated. Also, I'll only provide some info on how to build this repo and flash the code.

Note: The http://www.ti.com/lit/zip/slac388 support package from TI is not available online anymore and I couldn't also find it anywhere. For this reason I was only able to flash the firmware via USB and using mspdebug

Configure the firmware

You can configure the firmware and select which modules you need. To do this, run:

docker run --rm -it -v $(pwd):/tmp -w=/tmp dimtass/msp430-cde-image:latest -c "python ./tools/config.py"

Then select the modules you need. After this you need to create the modinit.c file. To do this run the following command:

docker run --rm -it -v $(pwd):/tmp -w=/tmp dimtass/msp430-cde-image:latest -c "python ./tools/make_modinit.py"

Building the firmware

It's better to use the docker image in order to build the firmware, so you don't have to install the toolchain and several other packages needed for the image. In order to do this you need to run the following command:

docker run --rm -it -v $(pwd):/tmp -w=/tmp dimtass/msp430-cde-image:latest -c ./build.sh

The above command will create a new folder ('build-msp430/) and build the firmware in there. The resulted file will be the openchronos.elf`.

Flashing the firmware

In order to flash the firmware you need the mspdebug tool, but you don't have to install it because it's already installed in the docker image. Nevertheless, you need to give docker access to the USB ports, therefore you need to run the following command (after you've built the firmware)

docker run --rm -it --privileged -v /dev/bus/usb:/dev/bus/usb -v $(pwd):/tmp -w=/tmp dimtass/msp430-cde-image:latest -c ./flash.sh
