These are the steps taken to setup piCore 14 on a Raspberry Pi with only Wi-Fi (no ethernet)
Newer version might work as well (or maybe even better), but have not been tested.
- Download the piCore image
- Unpack the
.zip
file and write the.img
file to the SD-Card (using Raspberry Pi Imager for example) - Move the SD-Card to the Pi, plug in a keyboard and a screen, plug in the power source
- Execute
backup
shell command after the first boot to save generated unique SSH keys which will be used during next boots.
