#x100 will generally do it for me, for the past 50 years. Reads back as a 2-byte stream as 00 01 on little-endian, and 01 00 on big-endian.
But yes, ARM is like Intel, little endian.

Hello everybody,
I am in a rabbit hole (don't ask!), and I need to drag some other people with me.
What is the consensus about the most portable way to detect the endianness of a machine/platform? (Ok, we can assume that while running on an ARM the endianness is "fixed" by the OS)
All the best
