I am not asking about the discontinuation of manufacturing or selling of the hardware; I am talking about only the software.

There are famous old Android devices that the manufactures have abandoned a long time ago, but users are providing custom ROM's. As far as I know, even though those come with latest Android security patches, the underlying low-level parts of the software cannot be updated because only the device manufacturers can make them. And I have heard that manufactures like Qualcomm provide such security updates only for a short time.

So, my question is, what about RP? Say, if I buy a cheap used RP 1 or 2, is it still safe? That is, can I get low-level security patches? And if they are, how long can I expect them to get software updates (both low-level software and the operating system)?

  • Yes, it's safe. A Pi 1 (I have 1) is considered slow nowadays, but I run Tomcat and a Wiki there, with no problems. In terms of security, just keep it up to date. Commented Jul 11, 2020 at 1:47

The same version of Raspberry Pi OS works on all Pi models.


  • But lower-level software like, I don't know, drivers or firmware for parts that were made by Broadcom, etc. Do they also get the same treatment? Commented Jul 6, 2020 at 18:17
  • Drivers and firmware generally are part of the operating system in Linux.
