Description

I'm working on a project based on the NXP K20 series of processors (of Teensy 3.2 fame) and I am in need of an RTOS. Unfortunately this series of chips lack hardware memory protection.

My use case doesn't require the security guarantees an MPU would provide, but is Hubris able to function without one?

I don't mind getting my hands dirty but I want to make sure this isn't a fool's errand.

Research direction

Start with the Hubris architecture and the K20/Teensy 3.2 hardware described in issue #326. Determine whether the kernel can run without hardware memory protection, then document the required changes or conclude that it cannot; no target files or tests are identified in the issue.
