Using the official configuration to build a stable OpenWrt 23.05.2 image for Raspberry Pi 4B.

Obtaining the Source Code

Clone the OpenWrt Git repository with the command below.

git clone https://git.openwrt.org/openwrt/openwrt.git [destination_path]
# Omit [destination_path] to clone into the current directory.
# Otherwise, specify a path like ~/development/openwrt-build/

Selecting the Stable Release v23.05.2

Switch the Git working tree to the specific stable release tag.

git tag -l | grep 23.05.2  # List available tags for 23.05.2
git checkout v23.05.2       # Check out the specific version

Updating and Installing Package Feeds

Update the list of available packages and install them into the build system.

./scripts/feeds update -a
./scripts/feeds install -a

If the ./scripts/feeds commands are not found, ensure necessary build tools are installed. For example, on Debian-based systems:

apt search qemu-utils  # Search for required package
apt install qemu-utils # Install the package

Due to potential network issues, its advisable to run the feed commands repeatedly until they complete successfully without errors. A successful update output resembles:

$ ./scripts/feeds update -a
Updating feed 'packages' from 'https://git.openwrt.org/feed/packages.git^8e3a1824645f5e73ec44c897ac0755c53fb4a1f8' ...
Updating feed 'luci' from 'https://git.openwrt.org/project/luci.git^7739e9f5b03b830f51d53c384be4baef95054cb3' ...
Updating feed 'routing' from 'https://git.openwrt.org/feed/routing.git^83ef3784a9092cfd0a900cc28e2ed4e13671d667' ...
Updating feed 'telephony' from 'https://git.openwrt.org/feed/telephony.git^9746ae8f964e18f04b64fbe1956366954ff223f8' ...
Create index file './feeds/packages.index'
Create index file './feeds/luci.index'
Create index file './feeds/routing.index'
Create index file './feeds/telephony.index'

A successful installation output looks like:

$ ./scripts/feeds install -a
