What about "halt"?   man halt

Meino, "it's an embedded system". That can mean unique hardware, via
the SoC, hidden codes via the in-situ firmware, or a myriad of things
hidden in the "recommended" kernel(s).  Many embedded developers
forked off their own "embedded kernel" form linux via the 2.2 or 2.4
kernel series.

So, you have to "fully characterize" the system. Which is difficult to
impossible, as the vendor wants to retain control in most circumstances.
The good news is most "hardware vendors" are dumb, when it comes to codes;
so there is most always a work-around; hence "man halt" as for your
next leg of the journey?
