hi,
i just fixed some locking issues the last days. fix will follow. it took
a bit longer, because there were some race conditions. it took up to
about one hour until it crashed. my way to detect the area where the
crash happened, was to turn on buzzer before that area, and turn it off
after that area. after many hours of approximation, i finally found out
that the major crash happend during _talloc_zero. (first it looks for a
free memory chunk, then it allocates it.) since it can be called from
all contexts (main, irq, fiq), it need to be locked against any
interrupt, otherwise the memory chunk can be assigned multiple times.
(the process of _talloc_free is "atomic" and requires no locking.)
because it seems pretty stable, i think it is time to merge some
branches into the master. (i made a 6 hours call yesterday. and no crash
after bugfix ever since.) i will do that together with sylvain, if we
find the time this weekend.
currently i use the jolly/voice together with the sylvain/traffic
branch. i am able to use an isdn phone togehter with linux-call-router
and make/receive calls. audio is passed both ways. i think this is a
stage where it actually become "usable". (if not moving arround.)
one of my major work for the next weeks/months will be the neighbour
cell measurement, cell re-selection, and handover. this is essential
when moving with the phone.
regards,
andreas
Hello All,
I can't compile after the last pull. I know that it is an error with
toolchain detection but I have tried almost everything.
-------------------------------
As you can see the $PATH variable has the address to gnu-arm-elf binary :
arslan@arslan-Lenovo-B575:~/osmocom-bb/src$ echo $PATH
/home/arslan/arm-elf/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
-------------------------------
and when I list the items in that directory I can clearly see that the
binary is there :
arslan@arslan-Lenovo-B575:~/arm-elf/bin$ ls
arm-elf-addr2line arm-elf-cpp arm-elf-ld arm-elf-size
arm-elf-ar arm-elf-g++ arm-elf-nm arm-elf-strings
arm-elf-as arm-elf-gcc arm-elf-objcopy arm-elf-strip
arm-elf-c++ arm-elf-gcc-4.0.4 arm-elf-objdump
arm-elf-cc arm-elf-gccbug arm-elf-ranlib
arm-elf-c++filt arm-elf-gcov arm-elf-readelf
-------------------------------
But I still get the following error:
/home/arslan/osmocom-bb/src/target/firmware/include/asm/swab.h:
Assembler messages:
/home/arslan/osmocom-bb/src/target/firmware/include/asm/swab.h:32:

Dear Sylvain
While Decoding AMR do need to just decode and pack it into raw amr frames
or we need to think about hysterasis and all parts also
also there are total 8 codec modes
but in band data have details of on 4 codec modes
which one to choose out of 8 codec modes from those 8 modes.

Hi list,
I am trying, with no success so far ,to chain-load the trx-firmware on my c118 with usb-serial-cable.:
------output-----
./osmocon -p /dev/ttyUSB0 -m
c123xor -c ../ ../target/firmware/board/compal_e88/trx.compalram.bin ../ ../target/firmware/board/compal_e88/chainload.highram.bin
got 2 bytes from modem, data looks like: 04 81 ..
got 5 bytes from modem, data looks like: 1b f6 02 00 41 ....A
got 1 bytes from modem, data looks like: 01 .
got 1 bytes from modem, data looks like: 40 @
Received PROMPT1 from phone, responding with CMD
opening file: No such file or directory
------------------------------------
I also tried switching highram-compalram:
./osmocon -p /dev/ttyUSB0 -m
c123xor -c ../ ../target/firmware/board/compal_e88/trx.highram.bin ../ ../target/firmware/board/compal_e88/chainload.compalram.bin
And also
./osmocon -p /dev/ttyUSB0 -m
c123xor -c target/firmware/board/compal_e88/trx.compalram.bin target/firmware/board/compal_e88/chainload.highram.bin
but got same errors. I used the script in the wiki for building the toolchain prior to building the code.
----------------------------------
Any ideas what might be wrong?
Regards erich
Hi list,
Attached 3 patches for decoding UCS2 MT-SMS and incoming USSD.
Main idea: convert UCS2 text to UTF-8, check if terminal supports
UTF-8 and if yes - print, otherwise - print in hex, and notify VTY to
check mobile log (since we can't send UTF text to VTY, if someone
knows how to do it - please tell me).
Waiting for comments.
Thanks,
Pavel
Dear fellow Osmcoom developers,
it is my pleasure to finally announce the date + venue of OsmoDevCon
2013:
Date: April 04 through April 07, 2013
Place: IN-Berlin, Lehrter Str. 53, Berlin
Like last year, this is an event for developers of the various Osmocom
proejects. Reservation and confirmation of reservation is required.
The event is free of charge. The Room is made available by IN-Berlin
e.V., an Internet related non-profit organization. Lunch catering will
be sponsored (so far by sysmocom GmbH, but if any other sponsors come
up, we are happy to share the cost).
So all you have to cover is your own travel + accomodation costs, as
well as breakfast and dinner. If you are an active developer and cannot
afford travel/accomodation, please let me know and I'll see if we can do
something about it.
If you would like to attend, please send a message to
laforge(a)gnumonks.org applying for registration of the event. The
registration deadline is March 5, i.e. one week from now.
There is no detailed schedule of talks yet. I will start a separate
discussion suggesting / collecting topics in the next couple of days.
More information is (and will be made) available at
http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2013
Further discussion regarding the event should be directed at the
osmocom-event-orga(a)lists.osmocom.org mailing list, to avoid
cross-posting over the various project-specific lists.
Best regards and happy hacking,
Harald

Hi,
I'm having a try with your software. A small suggestion I can give you
is about the chapter "Starting OpenBTS" of your howto: a better way to
host the transceiver script is to create a new dir under the openbts
root (lets call it TransceiverOSMOCOM) that hosts your script. Then to
create a link in the apps dir that point to the new transceiver, to
follow the model openbts uses. This allows the user to switch between
many hardware pieces using the same openbts installation (if
compilation flags apply), avoiding to overwrite your script if openbts
compilation instructions are literally followed.
Just my 2 cents.
Dario.

hi all
i cant understand where i am wrong
when i run this command this is the response which i get
root@shahzeb-laptop:~/Desktop/toolchain/osmocom-bb/src/host/osmocon# ./osmocon -p /dev/ttyUSB0 -m c140xor -c ../../target/firmware/board/se_j100/layer1.highram.bin
got 1 bytes from modem, data looks like: 00 .
and then it gets hanged and nothing happens.
i have checked the cable aswell it seems like cable is working
i have consulted J100i_cable.pdf for the data cable.
i would really appreciate your help
thanks

Hi,
I have about 8 broken C118 and wonder if someone would be interested
to save them from the recycling system. The defects vary but in some
cases it is a broken buzzer, issues with the SIM card holder, missing
or broken audio socket. This will just be the phone, no battery, no
charger.
I would like to get rid of them in batches of two. Is anyone interested?
The postage should be paid by the receiver.
cheers
holger
