RPi 4 von USB booten

RPi 4 unterstützt derzeit kein komplettes Booten von USB-Geräten. Möglich ist jedoch, dass die Boot-Partition auf der SD-Card liegt, das System auf einem USB-Gerät.

Vorbereitung

  1. SD-Karte flashen
  2. USB-Laufwerk flashen

Zum Flashen kann zum Beispiel Etcher verwendet werden.
