Hi All
Just wanted to confirm that I got Osmocom-BB up and running on a Raspberry Pi.
I did not use the GPIO UART pins but USB <-> serial converters.
I tried Motorola C118 and C155 with success.
Everything you need is already described:
http://bb.osmocom.org/trac/wiki/GnuArmToolchainhttp://bb.osmocom.org/trac/wiki/libosmocorehttp://bb.osmocom.org/trac/wiki/Software/GettingStarted?redirectedfrom=Gett…
My previous problem seems to have been a not fully compatible crosscompiled toolchain. (it worked mostly, but I could not log-in to a cell and the spectrum view crashed on the RSSI Firmware.
Also if you want transmit capability (or flashing) then you need to activate those features in the makefile.
Thanks Sylvain (confirming c118 will work) and all others who are involved!!
PS: Any news on the "emulated BTS" that has been presented at last years chaos communication congress?
I have 2 C118s + 1 normal USB serial dongle + 1 capable of burst ind.
I hope this will suffice to also run also a possible future 1 trasmit phone + 1 receive phone configuration.
I assume that even without the filter change it should be enough to send a few meters of distance.
I'm at the point w/ flashing firmware where I feel like I need to use a debugger w/ JTAG. I figured I could probably use serial line logging somehow but JTAG seems better and I should learn it anyway.
Has anyone pried open the shield on a c139/c140 and tried attaching to the JTAG test points that are just inside the shield next to the test points which are accessible via the battery compartment?
Hi folks,
Came across this article in the latest PoC||GTFO journal describing (part
of) the process for patching firmware on Nokia DCT4+ phones. The good
stuff is pages 22-29 of this file:
http://openwall.info/wiki/_media/people/solar/pocorgtfo03.pdf
Alas, this does not appear to permit patching the first 1MB of firmware, so
may not be helpful for OsmocomBB. But perhaps someone with more time on
their hands can take this and run with it...
Cheers,

Greetings,
I have a Motorola C139 handset with SW Ver 1.9.24 and a CP2102 USB/UART
adapter, which I hope(d) to use with osmocom-bb.
In Ubuntu 13.10 (running on [non-virtualized] hardware with an Intel i5-750
CPU), I compiled the toolchain, prerequisites, and osmocom-bb, but when I
run the following command (and then briefly press the phone's power button)
:
./osmocon -p /dev/ttyUSB0 -m c140
../../target/firmware/board/compal_e86/loader.compalram.bin
I get the following output:
got 7 bytes from modem, data looks like: 66 74 6d 74 6f 6f 6c ftmtool
Received FTMTOOL from phone, ramloader has aborted
got 1 bytes from modem, data looks like: 65 e
got 1 bytes from modem, data looks like: 72 r
got 1 bytes from modem, data looks like: 72 r
got 1 bytes from modem, data looks like: 6f o
got 1 bytes from modem, data looks like: 72 r
If I briefly press the power button repeatedly, I receive similar output.
I would greatly appreciate any suggestions as to how I might be able to
coax this into working.
Thanks,
Rusty D

I have just posted flash images read out of two C139s and one C140,
along with an annotated disassembly of the bootloader and other
reverse eng notes:

Hopefully someone will find it helpful...
To the OP: in case you haven't already figured it out, you need to use
-m c140xor with C139 and C140 phones. I don't know what phones would
-m c140 (w/o xor) be correct for, if any. Sylvain's direction to use
the -c option as well (and then use *.highram.bin instead of *.compalram.bin)
is also correct, because the images are bigger than the ~15k max one
can download w/o -c on this phone.
Also you said your C139 came with fw version "V1.9.24" - are you sure
it isn't V1.0.24 instead? The imprint on those stickers is a pain to
read, too small... If your fw version is actually V1.0.24, then it is
the exact same one I have just dumped and reverse-engineered.

I have ubuntu 10.04 installed on my system.
Will the osmocom-bb work fine on this version or do i have to install some
other version of ubutu on my system?
Its my 1st mail to the list.
I m doing research on osmocom-bb from couple of days.
Still m unable to understand what this software EXACTLY do. i.e. what are
its applications.
Can anyone help me out or share a much useful link which will help me
understand the use/applications of this software?
I'll be greatful
Hi all.
I've just noticed (yepp, I'm very observant :) that COPYING in libosmocore is GPLv2.
Is there any particular reason we still do not use GPLv3?
cheers,
Max.
Recently read some about the GSM CCCH SDCCH TS0 TS1 TS2 TS3 TS4 TS5 TS6 TS7
several data, seemed to understand a few, but about ccch_scan this program,
it takes TS0 or???
