Feel free to help us by extending the code. Always make sure to
|
||
|
send back all your patches to the baseband-devel@lists.osmocom.org
|
||
|
mailing list - Free Software is all about sharing.

== src/shared/libosmocore ==
|
||
|
|
||
|
is a library of various utility routines, including linked lists,
|
||
|
message buffers, bit-vectors, memory allocator, signals, select loop
|
||
|
handling, timers - as well as some more specifically GSM related things
|
||
|
like a TLV parser, a Comp128V1 implementation and utility functions for
|
||
|
RSL (TS 08.58) and CC/MM/RR (TS 04.08).
|
||
|
|
||
|
libosmocore is maintained in git://git.osmocom.org/libosmocore.git, so
|
||
|
|
||
|
DO NOT DIRECTLY COMMIT TO libosmocore IN THIS REPOSITORY!
|
||
|
|
||
|
We simply maintain a copy (synchronized by git-subtree) in this
|
||
|
repository for the ease of building and to make sure everyone is using
|
||
|
the proper/compatible version of libosmocore
|
||
|
|
||
|
Please note, whatever you add to libosmocore will need to build as a
|
||
|
Linux userspace program (using glibc) just as well as on the OsmocomBB
|
||
|
embedded target without OS. So please refrain from using fancy
|
||
|
functions.

|
== src/target/firmware ==
|
||
|
|
||
|
The firmware is what we build for the actual target (phone). It was
|
||
|
written with some idea of modularity in mind, i.e. we have
|
||
|
|
||
|
* Ti Calypso specific code in calypso/
|
||
|
* Analog Baseband code in abb/
|
||
|
* RF Mixer code in rf/
|
||
|
* Layer1 code in layer1/
|
||
|
* NOR flash handling in flash/
|
||
|
* LCD display handlin in display/
|
||
|
* minimal C-Library code in lib/
|
||
|
* communications utility routines in comm/
|
||
|
* Board (phone model/family) specific code in board/
|
||
|
* board/compal_e88 is the Motorola C115-C124 family
|
||
|
* board/compal_e99 is the Motorola C155 family
|
||
|
* Applications (each app builds one firmware image) in apps/
|
||
|
|
||
|
|
||
|
== src/target_dsp/calypso ==
|
||
|
|
||
|
This is where we keep some (assembly) code that we wrote for
|
||
|
the DSP that is part of the Caylypso DBB.
|
||
|
|
||
|
== host/layer23 ==
|
||
|
|
||
|
The Layer2 (LAPDm / TS 04.06) and Layer3 (CC/MM/RR / 04.08)
|
||
|
implementations, as they are growing.
