OpenWRT #

Image Builder #

Update #

I wrote openwrtbuilder to automate these steps for arbitrary configurations, so I can quickly build a new custom firmware.

The Image Builder (previously called the Image Generator) is a pre-compiled environment suitable for creating custom images without the need for compiling them from source. It downloads pre-compiled packages and integrates them in a single flashable image.

Look for the openwrt-imagebuilder-<target>-<type>.Linux-x86_64.tar.xz in the firmware image folder for your device. Download and extract it somewhere.

Get a list of available profiles with make info. For my TP-Link Archer C7 v2:

• imagebuilder: openwrt-imagebuilder-ar71xx-generic.Linux-x86_64.tar.xz
• profile: archer-c7-v2

You can include extra packages by configuring PACKAGES=.

make image PROFILE="archer-c7-v2" PACKAGES="-ppp -ppp-mod-pppoe luci-ssl wireguard"

The result will be stored in ./bin/targets/<target>/<type>/.
