Currently, the Raspberry Pi 3 is the only model supported. Many people assume the Raspberry Pi Zero W could be used as well. Unfortunately, it uses the older BCM2835 SoC, which is not arm64, so gokrazy won’t run on it. See also stapelberg’s reddit comment about supported hardware.
If you don’t already have Go installed, install Go 1.8.
go get -u github.com/gokrazy/tools/cmd/gokr-packer
Plug an SD card into your card reader and locate its device node by checking
dmesg | tail. In this example, we’ll assume the SD card is accessible as
To overwrite the entire SD card
/dev/sdb with a gokrazy installation running a hello world program, use:
sudo setcap CAP_SYS_ADMIN,CAP_DAC_OVERRIDE=ep $(go env GOPATH)/bin/gokr-packer gokr-packer -overwrite=/dev/sdb github.com/gokrazy/hello
gokr-packer command above will result in log output like this:

After booting from this SD card, your Raspberry Pi 3 will:
