Setting up yotta for mbed 🔗

• https://lancaster-university.github.io/microbit-docs/offline-toolchains/
• Install yotta

  sudo apt-get update && sudo apt-get install python-setuptools  cmake build-essential ninja-build python-dev libffi-dev libssl-dev && sudo easy_install pip
  
  # Apparently its necessary to use the ARM-maintained gcc-arm-embedded package (http://docs.yottabuild.org/#installing)
  # remove the built-in package, if installed:
  sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi
  # set up the PPA for the ARM-maintained package:
  sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
  sudo apt-get update
  # install:
  sudo apt-get install gcc-arm-embedded
  
  #Make virtualenv for python2.7 and pip install
  pip install yotta

• For the micro:bit targets you currently still need the srecord tools, which can be installed on Ubuntu

  sudo apt-get install srecord

• Download mbed example to test

  git clone https://github.com/lancaster-university/microbit-samples
  cd microbit-samples

• Set Yotta target and build

  yt target bbc-microbit-classic-gcc
  yt build

• Flash the micro:bit
  • The yt build command will place files in /build/<TARGET_NAME>/source. The file you will need to flash will be microbit-samples-combined.hex. Simply drag and drop the hex onto the MICROBIT usb device.

  cp ./build/bbc-microbit-classic-gcc/source/microbit-samples-combined.hex /media/MICROBIT
