[PATCH 0/2] Remove some leaked-in calypso dependencies
by Wolfram Sang 30 Apr '11

30 Apr '11

Hi, good news: mails are back bad news: phone lost a battery pin :( Here are two small patches to help the mediatek-branch compile without calypso references. These were tested before the breakage and 'make all' still builds fine for compal. Regards, Wolfram Wolfram Sang (2): comm: msgb: don't set backlight on error lib: move delay.c from calypso to lib src/target/firmware/calypso/Makefile | 2 +- src/target/firmware/calypso/delay.c | 16 ---------------- src/target/firmware/comm/msgb.c | 1 - src/target/firmware/lib/Makefile | 2 +- src/target/firmware/lib/delay.c | 16 ++++++++++++++++ 5 files changed, 18 insertions(+), 19 deletions(-) delete mode 100644 src/target/firmware/calypso/delay.c create mode 100644 src/target/firmware/lib/delay.c -- 1.7.2.5

libosmocore viterbi decoder
by mad 29 Apr '11

29 Apr '11

Hi Sylvain, hi list! I saw you commiting a generic viterbi de-/encoder in libosmocore core/conv.c. Just when I started to learn how to implement something like that some days ago... :-) Now I'd like to know if there are also some precomputed tables available for next_output and next_state implementing the convolution codes described in GSM 05.03/3.9. Regarding the soft input bits to the algo, my guess is when just having hard bits you have to simply convert 1 to 127 and 0 to -127 in sbit_t, right? And what came to my mind while reading the code is that couldn't you improve its performance on punctured codes by remembering the re-inserted bits and excepting them from next accumulated error calculation (line 291)? If I'm understanding viterbi the right way, as punctured bits doesn't contain any information and introduce some random additional error, only real input bits should be incorporated in state decisions. Regards, Mad

[PATCH] target/boards: add infrastructure for loaders for Mediatek platforms
by Wolfram Sang 29 Apr '11

29 Apr '11

We are just interested in the loaders here, no other applications needed. Split it from the compal-based phones. Add mt62xx as first user. Based on a patch by Steve, but cleaned up and seperated from compal/calypso. Signed-off-by: Steve Markgraf <steve(a)steve-m.de> Signed-off-by: Wolfram Sang <wolfram(a)the-dreams.de> --- The new loader was succesfully tested on my Sciphone G2 by loading and executing a bootloader.

RE:Nokia 3310 tracing

It shows the communication messages like Osmocom? Does it also supports SMS messages? Maybe you can also write a small wiki on how to use (with Wireshark).

Merging G2-loader
by Wolfram Sang 29 Apr '11

29 Apr '11

Hi, do the following assumptions and conclusions make sense? - The Sciphone G2 is intended as a platform where we want to run L1/2/3 natively on Linux (somewhen). - Thus, from all the applications in osmocom-bb for the targets, we only need the loader to get the first bootloader onto the system (in case JTAG is not available or wanted) - Being that different, it doesn't make sense to fit the mediatek-platform into the existing makefile-templates which build all applications for all boards. I'd suggest to create a new top-level target "mtk" which only builds the loaders for mediatek-phones. All unneeded applications and libraries are skipped. A preview of a possible directory-structure to add mtk-support could look like this then: . ├── board │ ├── mediatek │ │ ├── exceptions_redirected.S │ │ ├── exceptions_redirect.S │ │ ├── handlers.S │ │ ├── header.S │ │ ├── macros.S │ │ ├── ram.lds │ │ ├── start.ram.S │ │ ├── start.rom.S │ │ └── uart.c │ └── mt62xx │ └── init.c └── include └── mtk ├── bfe.h ├── bpi.h ├── bsi.h ├── emi.h ├── mt6235.h ├── mt6235_sciphone_g2.h ├── system.h └── tdma_timer.h It can be cleaned up a bit once there is a working state. Of course, a few modifications to makefiles are also needed. Note there is now a seperate uart.c in the mediatek-folder. Any objections? Anything I missed? Regards, Wolfram

Re: Transmitting voice with Osmocom

Thank you very much. A firm from Turkey called Aselsan succeeded to make encrypted conversation over GSM. It transfers the voice data (1.2 kbit/s ) with Synthetic Voice Modulator technology. http://www.aselsan.com.tr/images/dokuman/HC/AHSPD/kripto/2110/2110_whitepap…

Transmitting voice with Osmocom
by Michael Dvoishes 28 Apr '11

28 Apr '11

Hi All, I am trying to transmit voice with my GTA02 and Osmocom. Upon looking into code I did not find any code transmitting voice. I have tried to do it myself but without much success. What have I done: 1. Merge branch "jolly/voice" into main. 2. Add handling of L1CTL_VOICE_REQ at l23_api.c 3. Create additional queue for voice requests to be handled within the scheduler 4. Create "loopback" code, issuing L1CTL_VOICE_REQ each time voice is received at layer23 5. At l1s_tch_cmd, add code, sending the frame from voice request queue, similar to code, sending FACCH frame. 6. During tests against OpenBTS, it appears, that the voice frames are being sent, but all of them have "Stolen" bit turned on, e.g. BTS considers them FACCH frames. My question is how do I transmit TCH frame with "Stolen" indicator turned off. Or even better, is there any other implementation of transmitting voice via TCH? Code fragment from l1s_tch_cmd, ------------------------------------------------------------------------------------------------ if (facch_tx_now) { uint16_t *info_ptr = dsp_api.ndb->a_fu; struct msgb *msg; const uint8_t *data; /* Pull FACCH data (if ready) */ if (icnt > 26) { msg = msgb_dequeue(&l1s.tx_queue[L1S_CHAN_MAIN]); if(!msg && (tch_mode == TCH_FS_MODE)) { msg = msgb_dequeue(&l1s.tx_queue[L1S_CHAN_VOICE]); if(msg && msg->l3h) { tx_sent++; printf("rx_frames: %d tx_recv: %d tx_sent: %d\n", rx_frames, tx_recv, tx_sent); printf("l1s_tch_cmd: voice data = %s\n", hexdump(msg->l3h, 33)); } } } else { msg = NULL; } ------------------------------------------------------------------------------------------------ Many thanks Michael
