Moving from netos to linux

Hi all
I have question. I have been recently trying to develop project using NETOS but I am totally disapointed with possibilities of catching bugs in software. I believe embeeded linux will be better in application, so I want to try it. Currently I have two modules with cc9p9015 with licence to NETOS system. My final question is, is it possible to move to linux without buying another module licensed to linux? Where can I get DIGI tools for linux os?
