OpenWRT-x86_64-Install

This is a turn key script to create an OpenWRT x86_64 bootable image for Legacy and EFI bootup. This installing has only been tested on Ubuntu 20.04, but there is no reason why it would not work on earlier releases.

	OpenWRT x86-64 Installation

	Version: 1.0.0

	Usage:
		-b [master]			OpenWRT install branch
		-c [LEGACY|EFI] <DEV_BLOCK>	Create bootable media	Example: -c EFI /dev/sdb
		-f 				Fresh Install, Remove previous installation
		-i  				Ignore Warning and Error Suppresion
		-r				Remove OpenWRT directories, then exit
		-m				Build OpenWRT
		-h				Print usage and exit
		-v				Print version and exit

Usage

Install OpenWRT master branch

	createOpenWrtInstant.sh

Install OpenWRT master branch and build image

	createOpenWrtInstant.sh -m

Install OpenWRT master branch, build image and create bootable ext4-fs image on media

	createOpenWrtInstant.sh -m -c EFI /dev/sdb

Reinstall OpenWRT master branch when there is an existing OpenWRT

	createOpenWrtInstant.sh -f

Manual steps to prepare installation

Step 1:

Copy and Paste the following and make sure that each of the required packages are installed. You may need to run this a couple of times.

sudo apt-get install git
sudo apt-get install make
sudo apt-get install gcc
sudo apt-get install binutils
sudo apt-get install bzip2
sudo apt-get install flex
sudo apt-get install python
sudo apt-get install python3.5+
sudo apt-get install python2-doc python-tk python2.7-doc binfmt-support
sudo apt-get install libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib python-is-python2 python2 python2-minimal python2.7 python2.7-minimal
sudo apt-get install perl
sudo apt-get install grep
sudo apt-get install diffutils
sudo apt-get install unzip
sudo apt-get install getopt
sudo apt-get install subversion
sudo apt-get install libz-dev
sudo apt-get install libc
sudo apt-get install g++
sudo apt-get install gawk
sudo apt-get install zlib1g libncurses5 g++ flex
sudo apt-get install build-essential libncurses5 zlib1g flex
sudo apt-get install libncurses-dev

Step 2:

git clone https://github.com/mgarcia01752/OpenWRT-x86_64-Install.git

Step 3:

This step will:

1. Clone and create the required OpenWRT directories.
2. Create a feeds.conf file that is needed to point the required packages to the local computer
3. Copy a base x86_64 configuration file that is needed to setup the gcc toolchain for compiling

Copy/Paste the following:

cd OpenWRT-x86_64-Install
createOpenWrtInstant.sh -m

At this point, you will have an image to manually install on whatever media you prefer. Steps 4 and 5 will provide some guadiance.

You can use -c option to have the script install the image for you. Make sure you select the correct media device.

Step 4: Manual step to copy image onto media

Determine the media block device location

4.1 List block devices

	lsblk -I 8 -d
	
	NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
	sda    8:0    0 465.8G  0 disk 
	sdb    8:16   1 465.8G  0 disk 

4.2 Insert USB or mSATA drive

4.3 List block devices again

	NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
	sda    8:0    0 465.8G  0 disk 
	sdb    8:16   1 465.8G  0 disk 
	sdc    8:32   1   7.5G  0 disk

4.4 Make note of the change

	sdc    8:32   1   7.5G  0 disk
	
	/dev/sdc

Step 5:

Prepare media drive for image
	
	drive="sdc"
	printf "o\nn\n\n\n\n\nt\nc\nw\n" | sudo fdisk /dev/${drive}
	sudo mkdosfs /dev/${drive}1

Step 6:

	drive=sdc
	gzip -dc openwrt-x86-64-generic-ext4-combined-efi.img.gz | sudo dd of=/dev/${drive} bs=1M status=progress && sync
