EEPROM.put() endianness

ARM processors are actually "bi-endian". They will operate big-endian, little-endian, or both, depending on how the processor logic is configured when the chip is designed.

I don't think I've ever seen a big endian Cortex-M microcontroller.

@RayLivingston

he vast majority of the ARM-based chips I've designed and used over the last 20 years were implemented as big-endian, including the Due

The SAM3X8E on the Due is little-endian:
