This might be the coolest thing I have seen so far: There exist an open source distributions of AUTOSAR!
And it's local to us here in Gothenburg, should I be embarassed for not hearing about this earlier?
Caveat: Note that if you intend to use AUTOSAR in a business setting you need to fulfill the conditions according to the AUTOSAR consortium.
After some e-mail exchange I now know that the open source AUTOSAR BSW software (ver 3.1) is available under a GPLv2-license.
