Can a netPI RTE 3 be turned into a netFIELD Connect - Armin@netPI - December-23rd-2020

In short: even if netPI RTE 3 and netFIELD Connect devices are the same hardware their system software cannot be exchanged in between. So you cannot upgrade your netPI to be a netFIELD Connect.

The reason is the security enhanced boot feature of netPI's and netFIELD Connect OS. Their basis builds a signed Linux kernel that is digitally signed with signing keys that are different for each device model and per device serial number. On each power cycle the signature is checked or when system software is updated.

So you have to place a different order for each devices model:

  1. netPI RTE 3 - order NIOT-E-NPI3-51-EN-RE
  2. netFIELD Connect - order NIOT-E-TPI51-EN-RE/NFLD
Here are by the way again the differences between both devices
