YOCTO EC2

A project with some tools that may help embedded linux developers build linux image with Yocto on EC2.

The idea we may select a very cool EC2 with 16 cores and 32 GB RAM, this cost us ~$0.4 an hour for a build. We only run the EC2 once we start building the linux image and stop this once we are done. So, the EC2 does not cost us more than $30-$40 a month. it's cheaper than you invest super desktop to build the code, plus utility bill and cooler as well.

THE CURRENT VERSION IS ONLY SUPPORT NXP iMX SOURCE CODE

Setup AWS

1. Create EC2 instance:

   • Type: c5.4xlarge and ESB 120GB
   • OS: Ubuntu Server 18.04

   Note: Use ubuntu user for everything.

2. Add your ssh public key to the EC2

   • Copy your public key

     ssh-keygen
     cat ~/.ssh/id_rsa.pub | pbcopy

   • Paste the key to EC2

     vim .ssh/authorized_keys

Clone source code and initialize build environment

Clone your code to your EC2

Installation

pip install yoctoEC2

For current version, I suggest you to initialize build environment and accept EULA by manual.

Yocto build

You may want to modify build script build.sh with your project parameters.

Start EC2, build, copy image and Stop EC2

yocto-ec2 build --instance-id=<instance-id> --project-root=<project-path> --DISTRO=<distro> --MACHINE=<machine> --IMAGE=<image>

yocto-ec2 build --instance-id=i-12345678  --project-root=/home/ubuntu/Workspace/iMX6ULEVK/ --script-path=./build.sh --sdcard-image=/home/ubuntu/Workspace/iMX6ULEVK/build/tmp/deploy/images/imx6ulevk/core-image-base-imx6ulevk.sdcard.bz2
