I assume you're a MTI customer? If so I suggest you talk to customer
support. There are docs, SDE-based toolchain and example code showing
how to use this. If you understand the technical details it will not
be too difficult to figure out your own solution using a standard
Linux/MIPS toolchains but of course in that case you can't use any of
the userspace libraries for building an AP/SP program.
