I don't understand, they cmd and args are defined as uint32_t, however,
looking at the returned data, they all look like 64-bit things:
print("result", bin.unpack("HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH", result))
FF 00 00 00 00 00 00 00 <-- 64 bits of data
FE FF FF FF 00 00 00 00 <-- 64 bits of data

00 00 00 00 00 00 00 00 <-- 64 bits of data
04 7F 12 E2 00 <-- this is where 'data' starts
So below I use LI to pick out the "FEFF FFFF", don't know why it works..
