3 Feel free to help us by extending the code. Always make sure to
4 send back all your patches to the baseband-devel@lists.osmocom.org
5 mailing list - Free Software is all about sharing.
7 == src/shared/libosmocore ==
9 is a library of various utility routines, including linked lists,
10 message buffers, bit-vectors, memory allocator, signals, select loop
11 handling, timers - as well as some more specifically GSM related things
12 like a TLV parser, a Comp128V1 implementation and utility functions for
13 RSL (TS 08.58) and CC/MM/RR (TS 04.08).
15 libosmocore is maintained in git://git.osmocom.org/libosmocore.git, so
17 DO NOT DIRECTLY COMMIT TO libosmocore IN THIS REPOSITORY!
19 We simply maintain a copy (synchronized by git-subtree) in this
20 repository for the ease of building and to make sure everyone is using
21 the proper/compatible version of libosmocore
23 Please note, whatever you add to libosmocore will need to build as a
24 Linux userspace program (using glibc) just as well as on the OsmocomBB
25 embedded target without OS. So please refrain from using fancy
29 == src/target/firmware ==
31 The firmware is what we build for the actual target (phone). It was
32 written with some idea of modularity in mind, i.e. we have
34 * Ti Calypso specific code in calypso/
35 * Analog Baseband code in abb/
36 * RF Mixer code in rf/
37 * Layer1 code in layer1/
38 * NOR flash handling in flash/
39 * LCD display handlin in display/
40 * minimal C-Library code in lib/
41 * communications utility routines in comm/
42 * Board (phone model/family) specific code in board/
43 * board/compal_e88 is the Motorola C115-C124 family
44 * board/compal_e99 is the Motorola C155 family
45 * Applications (each app builds one firmware image) in apps/
48 == src/target_dsp/calypso ==
50 This is where we keep some (assembly) code that we wrote for
51 the DSP that is part of the Caylypso DBB.
55 The Layer2 (LAPDm / TS 04.06) and Layer3 (CC/MM/RR / 04.08)
56 implementations, as they are growing.
