Homebrew Reverse System Services

[gudenau]

How would one go about reverse engineering a system service? There are some projects that I would like to work on, but there is very little documentation for the services I need. These are arm11 services I am talking about. I can't really use IDA for this, fast to expensive; my budget requires free.

Is the free older version of IDA not suitable? I don't remember what the restrictions are.

No ARM.

Ah ok...
neobrain mentioned a free arm disassembler, I think in his braindump thread.

I know GCC can do it, this is more of a "where to start" thread.
