Revision 32 (gnutoo, 02/19/2016 10:49 PM) → Revision 33/57 (Anonymous, 02/19/2016 10:49 PM)

== Introduction == 
 This page is a code audit that: 
  * Verify if the license are correct(not copied from osmocom-bb and changed from GPL to BSD) 
  * permit to view the license of each file, that's important for the inclusion into the official nuttx that only accepts BSD code for the non-applications part. 
 == Audit == 
 Currently the following files were added or modified by nuttx-bb(on top of nuttx):
