unlike Michael, I have intercourse regularily with nx_types. they are implemented as big endian byte arrays. And referenced using well known byte swappers on little endian machines automatically.

Does it work with reset(10)? > I see two choices for figuring this out (there maybe more but two stand out on the ledge to me). 1) use a real embedded debugger to see exactly what is going on. or 2) study the generated code and play computer and see if it is doing what you expect. I don't see anyway we can by inspection using the data we have out here in the wild can figure out from what you are telling us what is going on.
