On Windows, PowerShell’s Get-FileHash shows the SHA256.

Get-FileHash .\felixxrt-*.iso -Algorithm SHA256

Write it to a USB stick

The ISO can be written to a USB stick as is (everything on the stick is erased). On Windows use Rufus (“DD image” mode) or balenaEtcher; on Linux use dd.

# /dev/sdX is the USB stick (a wrong device is erased)sudo dd if=felixxrt-*.iso of=/dev/sdX bs=4M conv=fsync status=progress

Next, see “Installation” in the manual.

Updates

After installation, update from “Updates” in the web interface (packages come from the signed repository https://repo.felixxsv.net/felixxrt). There is no need to reinstall from the ISO.
