This repository holds a pre-built Linux kernel image for the Raspberry Pi 3, Pi 4, and Pi Zero 2 W, used by the gokrazy project.
The files in this repository are picked up automatically by
the gok tool, so you don’t need to interact with this repository
unless you want to update the kernel to a custom version.

This repository clocks in at over 3 GB of disk usage, so you might want to clone it as a shallow clone:
git clone --depth=1 https://github.com/gokrazy/kernel
First, follow the gokrazy installation instructions.
We’re using docker to get a reproducible build environment for our kernel images, so install docker if you haven’t already:
sudo apt install docker.io
sudo addgroup $USER docker
newgrp docker
Clone the kernel git repository:
git clone --depth=1 https://github.com/gokrazy/kernel
cd kernel
Install the kernel-related gokrazy tools:
GOBIN=$PWD/_build go install github.com/gokrazy/autoupdate/cmd/gokr-rebuild-kernel@latest
And build a new kernel (takes about 5 minutes):
(cd _build && ./gokr-rebuild-kernel -cross=arm64)
The new kernel is stored in the working directory. Use gok add . to
ensure the next gok build will pick up your changed files.
