Each application configures its own set of drivers, maximums, etc by specifying
the CONFIGURE_ macros like at the bottom of hello and then including
confdefs.h.
You need to add your driver to the set. From memory since on phone, this is via
CONFIGURE_APPLICATION_DRIVERS or something similar.
This is in the users guide in the configuring a system chapter.
