Thank you Gregory!
I have never really had time to dig into ARM's MPU implementation but the
reason I thought it was possible is because FreeRTOS 10 claims that its
unprivileged tasks can run segregated with access limited to its own stack
and up to three user definable memory regions. I guess I

Hi!
I am new to this list. I have played with Nuttx in the past but now there
is an opportunity to put it to use in a real application!
While this is exciting, I do have a question: considering an MCU with a
Memory Protection Unit, is it possible to have some threads running
isolated from each

Yes, this case is also in the initial design but we never used this before.
Glad to see it work for you.

Oh, now I understand how it works!
In my case, however, I also wanted a "simulated" UART, not a physical one.
So I run:
socat PTY,link=/dev/ttySIM0 PTY,link=/dev/ttyNX
and indeed our software was perfectly capable of
