-http://bb.osmocom.org/trac/wiki/nuttx-bb/run detail the usage of nuttx with

-sercomm(the transport used by osmocom-bb that runs on top of serial).

+Osmocom-BB Dependencies and Sercomm

+===================================

 

-The way of loading nuttx(which is also documented in osmocom-bb wiki) depend

-on the configuration(highram/compalram) and phone:

+The build environment assumes that you have the osmocom-bb project

+directory at same level as the nuttx project:

+

+  |- nuttx

+  |- apps

+  `- osmocom-bb

+

+If you attempt to build this configuration, you will get compilation errors

+in drivers/sercomm due to header files that are needed from the osmocom-bb

+directory.

+

+By defult, NuttX will use sercomm (HDLC protocol) to communicate with the

+host system. Sercomm is the transport used by osmocom-bb that runs on top

+of serial.  See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed

+the usage of nuttx with sercomm.

+

+Loading NuttX

+=============

+

+The osmocom-bb wiki describes how to load NuttX.  See

+http://bb.osmocom.org/trac/wiki/nuttx-bb for detailed information.

+The way that nuttx is loaded depends on the configuration (highram/compalram)

+and phone:

+

+o compalram is for the ramloader(for phone having a bootloader on flash)

+o highram is for phones having the romloader(if the phone has a bootrom)

+  or for loading in the ram trough a special loader(loaded first on ram

+  by talking to the ramloader) when having a ramloader(which can only

+  load 64k).
