Ok, so if you feel that your code is now no longer related to that since it is actually completely rewritten I think it is no problem. Otherwise, if you think there may still be code from there, the one you linked is MIT so at least I think it could be a compatible license with Apache 2.0.
Do you have your code available somewhere? That way I can take a look and think how it can be integrated to NuttX. Also, if you can place the apropriate license header already it would be better.
