Setting endian/byte order through disassemble command?

Hello,

I am working on auto-analysis with lldb using ARM (thumb) disassembly,
but am having problems with the 'disassemble' command. It seems that
llvm is defaulting to big-endian processing, and I cannot figure out
how to switch the mode to little endian. Here is the output:

(lldb) disassemble -A thumb -b -s 0x687f4 -e 0x68808
