The term endianness is used to describe the ordering of individually addressable quantities, which means bytes and halfwords in the ARM architecture. The term byte-ordering can also be used rather than endian.
If an image is loaded to the target on connection, the debugger automatically selects the endianness of the image otherwise it selects the current endianness of the target. If the debugger detects a conflict then a warning message is generated.
You can use the
set endian command to modify the default debugger setting.
