Prepare OpenWRT 21.02.x on Ubuntu 20.04

Prepare The System

  • This page will cover the preparation work for you to be able to build the OpenWRT based MESHdesk firmware.
  • The SDK and build process will require ~30-40G of hard drive space.
  • Install the required packages to ensure the SDK can build the firmware.
sudo apt-get update
sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev xsltproc libxml-parser-perl unzip mercurial
  • Create the location for the SDK
  • Our suggestion is to create a folder that will indicate the version of the firmware you'll be building.
  • Here we create a folder for the 21.02.0 release.

The 21.02.1 release (current at the time of this writing) have not yet been tested extensively by us.

# Create the working directory 
mkdir 21.02.0
# Change to our working directory 
cd 21.02.0

Checkout the SDK

  • Do a clean checkout of the OpenWRT repository.
 git clone https://git.openwrt.org/openwrt/openwrt.git
  • This repository has various branches. To see which branches are available and which one we are currently set to use, issue the following command.
#We may first need to change our directory to the openwrt directory
cd openwrt
git branch -a
#Also to see the tags 
git tag -l
  • We will be checking out the v21.02.0 tag.
git checkout v21.02.0
  • Confirm that this v21.02.0 is now checked out.
git branch
  • Update the package feeds.
./scripts/feeds update

  • Ensure the following packages are installed since they are required by the MESHdesk package.
./scripts/feeds install coova-chilli
