This image inherits base buildpack.

Overview

This buildpack contains a cross-compiler and other build tools configured for the Raspberry Pi. The toolchain is built using the crosstool-ng toolchain builder.

Building image

Before building this image, build or pull buildpack-base.

This image takes about 45 minutes to build. Go grab a coffee :coffee:

port BUILDPACK_IMAGE=raspberry-pi
t clone "git@github.com:spark/buildpack-${BUILDPACK_IMAGE}.git"
 buildpack-$BUILDPACK_IMAGE
scripts/build-and-push

TODO: The rest of the REAME needs to be updated for RPi

Running

t clone -b feature/raspberry-pi https://github.com/particle-iot/firmware.git
dir -p ~/app && mkdir -p ~/output && mkdir -p ~/cache
uch ~/app/application.cpp
cker run --rm \
 ~/firmware:/firmware \
 ~/input:/input \
 ~/output:/output \
 ~/cache:/cache \
rticle/buildpack-raspberrypi

Firmware repository

The Particle firmware has to be placed in ~/firmware

Input files

Source files have to be placed in ~/input

Output files

After build ~/output will be propagated with:

• run.log - stdout combined with stderr
• stderr.log - contents of stderr, usefull to parse gcc errors

Files only available if compilation succeeds:

• firmware.bin - compiled firmware

Updating the toolchain

To update the toolchain, run ct-ng to generate a new .config file, update the repo with this .config file and rebuild the buildpack.

er run --rm -ti particle/buildpack-raspberrypi /bin/bash
tmp

< .config
py-paste the current .config and press Ctrl-D

g menuconfig

.config
py-paste the new config into the git repo and rebuild the container
