Way to build embedded firmware?

[ondra_knezour]

Hello All,

we have couple of types of diferent embedded HW, mainly Realtek/Atheros MIPS based routes running some kinds of Linux. I want to start experimenting with FreeBSD on them and looking for advice how to do that, starting with flashable firmware.

So my questions are:
What information sources you can recommend,
What is known/tested on this field, what materials to study (I'm aware of little info available on FreeBSD Wiki) (http://wiki.freebsd.org/),
What is known to have been done, but nobody yet started/finished that,
What are esisting unresolved problems and ways to resolve them, proposed or known not been leadind to successfull end.

There is NanoBSD (http://www.freebsd.org/doc/en/articles/nanobsd/index.html) that's originally made for x86 embedded devices, but it shouldn't be too difficult to modify it to build to a MIPS target.

Have a look at the FreeBSD-embedded (http://lists.freebsd.org/mailman/listinfo/freebsd-embedded) list too.
