1 Official ZynthianOS SD-Images
This is the last official Zynthian SD-Image, based on Raspberry Pi OS:
You will need to unzip this file to provide an .img file that can be 'burnt' to an SSD disk that is bootable in the zynthian machine. This process differs depending on the Operating system you use for Internet access.
A raspberry Pi desktop instance will unzip from the file manager and provides the Imager application to write the SSD...
You will require a SSD Writer, but this task can be completed with only the raspberry Pi you are using for the zynthian with a little ssd disk swapping.
4 Preparing the SD-card
Current images are 8 GB compressed image file compiled for Raspberry Pi 3. These SD card images include all the Zynthian software, properly configured for working with the official kits. Completely ready to use. Plug and play!
After downloading the SD-image, you have to write it to a SD-card. You need a SD card with a minimum size of 16GB, although you can use a bigger one if you want.
5 Build your own image
If you like, you can build your own SD image following these instructions:
Also, you would like to try the new docker-builder (thanks @guysoft!!):
