little endian. arm v7.
Compiled for that

Errr... Can't think of anything intelligent to say beyond that.
We can also manage python and Java and a couple of other languages with the right installs first. But yeah little endian arm (armel) is the core guts.
Grab a copy of "buildroot" and check out one of the guides on here.
Give you a good grounding in the core options available/required IMHO

Also is a very capable system for porting efforts.
If I have underestimated your level of awesome I apologise.
