yoctoEC2 0.2.1

# 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

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

   • Paste the key to EC2

     `bash vim .ssh/authorized_keys `

## Clone source code and initialize build environment

Clone your code to your EC2

## Installation

`bash 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>

`bash 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 `
