Set up a Ubuntu VM on FreeBSD using vm-bhyve and install Micropython toolchain.

Tested with:¶

• FreeBSD 11.1-RELEASE-p8 + ZFS on baremetal server with virtualization support (host)
• Ubuntu Server 16.04.4 (guest, micropython build environment)
• Micropython 1.9.3 (esp8266 port)

How to:¶

• Install and configure vm-bhyve: Quickstart

• Recommended: set up tmux with vm-bhyve

• Create a vm for micropython

vm iso http://releases.ubuntu.com/16.04.4/ubuntu-16.04.4-server-amd64.iso

vm create -t ubuntu micropython
vm configure micropython

    loader="grub"
    guest="linux"
    cpu=1
    memory=2048M
    network0_type="virtio-net"
    network0_switch="public"
    disk0_type="virtio-blk"
    disk0_name="disk0.img"


vm install micropython ubuntu-16.04.4-server-amd64.iso
vm console micropython

• Finish Ubuntu installation inside console.

• Choose guided non-lvm partitioning.

• Optionally enable openssh server.

• Reboot guest, login

sudo apt-get update

sudo apt-get install -y make unrar autoconf automake \
  libtool gcc g++ gperf flex bison texinfo gawk \
  ncurses-dev libexpat-dev python-dev python python-serial \
  sed git unzip bash help2man wget bzip2 libtool-bin 

git clone --recursive https://github.com/pfalcon/esp-open-sdk

cd esp-open-sdk

make

echo "export PATH=/home/$USER/esp-open-sdk/xtensa-lx106-elf/bin:$PATH" >> ~/.bash_profile

exit

• Logout from guest, login

git clone --recursive https://github.com/micropython/micropython.git

cd micropython/ports/esp8266

make

• The firmware will be available as build/firmware-combined.bin.
