[PATCH 0/4] Fixes for gta0x targets
by Alex Badea 18 Nov '10

18 Nov '10

Hi all, I've been trying to join the party with my OpenMoko GTA02, and I found that a few tweaks were required. Patch 1/4 was required to get the romloader to start, otherwise osmocon would only receive an occasional '\x00' character instead of the ident_cmd. It works perfectly with the beacon interval reduced to 13 mS, but I've made it configurable just in case other targets don't like it. Patches 2/4 and 3/4 are bugfixes for the calypso uart code. The LCR register ended up being clobbered, and this rendered the uart on my board silent. Finally, I'm using the GTA02 AP as the "host", communicating via the internal ttySAC0 UART. Patch 4/4 allowed me to cross-compile osmocon & friends on my x86 box with the AP ARM as the target. Now I can run, ./osmocon -m romload -p /dev/ttySAC0 -i 13 -d tr firmware/layer1.highram.bin while toggling power via, echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on and get: OSMOCOM Layer 1 (revision osmocon_v0.0.0-696-ge801cee-modified) ====================================================================== Device ID code: 0xb496 Device Version code: 0x0000 ARM ID code: 0xfff3 cDSP ID code: 0x0128 Die ID code: e4942219e4949b52 ====================================================================== REG_DPLL=0x2413 CNTL_ARM_CLK=0xf0a1 CNTL_CLK=0xff91 CNTL_RST=0xfff3 CNTL_ARM_DIV=0xfff9 ====================================================================== Cheers, Alex Alex Badea (4): osmocon: make beacon interval configurable via cmdline target uart: fix preservation of LCR target uart: remove REG_OFFS() macro side-effect toplevel Makefile: accept arguments for host ./configure calls src/Makefile | 8 ++++---- src/host/osmocon/osmocon.c | 26 ++++++++++++++++---------- src/target/firmware/calypso/uart.c | 10 +++++----- 3 files changed, 25 insertions(+), 19 deletions(-)

Sciphone Dream G2 WLan MT5921

Hi, Harald Welte wrote: > bluetooth or FM radio.

This should be the same (or at least similar) chip built into the german Thalia/Bol/Buch.de Oyo ebook-reader (also released in France). The module is called mt5921sta_spi.ko and claims to be released under the GPL but until now no source release happened for any GPL component. The module is also contained in the firmware of the Booq Avant released in Spain (http://www.booqreaders.com/en/product_Avant) and possibly many more ebook-readers as these models seem to share their basic design.

Hello All, I have a question regarding GSMTAP , If it is used for sending messages to wireshark only or it has some other significant, like communication between L2 and L3 or communication with layer1, as the uint8_t and uint16_t were widely used in source code Kind regards,

Does anyone have any suggestions to fix this? Thanks!

Re: osmocom on windows

:D Yup the timers too. That's why I would like to keep that piece of code as it is and move only the serial port handling elsewhere (a different thread I) --- On Thu, 10/21/10, Holger Hans Peter Freyther <holger(a)freyther.de> wrote: From: Holger Hans Peter Freyther <holger(a)freyther.de> Subject: Re: osmocom on windows To: baseband-devel(a)lists.osmocom.org Date: Thursday, October 21, 2010, 8:09 PM On 10/21/2010 07:00 PM, eisencah eisenach wrote: > Here's another one.

850Mhz support
by Hugo Fortier 30 Oct '10

30 Oct '10

Hi everyone, I am fairly new to OsmocomBB. Been in North America I acquired a C118(850Mhz/1900Mhz version of the C123) and a C156(850Mhz / 1900mhz version of the C155) but from what I understand at this point is that only 900Mhz and 1800Mhz are supported. I am trying to figure out what modification I need to do in order to implement North American support for OsmocomBB, do I need to modify the firmware or do I only need to modify the host application? Any pointer would be greatly appreciated. I tried to modify the host application but I didn't had any success so far... Also I am trying to acquire a C123 and I find it quite difficult to find in North America, anyone know where I could acquire it from? I have look online but I could only find it on https://www.samstores.com/ and it seem a bit pricey and I have no idea if this store is trust worthy. I am also interested to acquire a BTS for OpenBSC(I currently have OpenBTS running on my USRP) so if you have any pointer on how I could acquire one, let me know. Thanks, Hugo

Hello All, Can Any one expert in programming add new command line in full stack GSM application like , ./mobile. to tune or enter for particular. ARFCN , Time slot, hopping sequence. my understanding here is , once i will logged to any cell , it will automatically find FCCH, and SCH and my MS will synchronize, to a cell and read bcch. only thing left over to finish my work is to tune to right ARFN and TS with appropriate HS i want signaling to be involved without it it wont receive TCH. see, to be frank my not expert in C language and even lots of try i couldn't make API for it . so any one can help me . Kind Regards,

L1 TCH code status
by Sylvain Munaut 29 Oct '10

29 Oct '10

Hi, Just a quick update for those that don't follow the git or IRC: A few days ago, I merged most of was in my sylvain/testing branch into master. It's now in a state where you can place a call on a BS11 or nanobts. It took a while for me to go from the raw prototype from Dieter to a state I was happy with. (especially because I wanted to understand the purpose of every line I was rewriting since my main goal is to learn :) There were also some extensions (mode switching / bugs fixes / partial HR support / ...). There are still somethings that are only in my testing/ because they're hacks (or even missing): - SIM support: The code is clearly [WIP]. I may get to cleaning it myself at some point, but that's not a priority for me ... - TS change fixup: There is a bug when going from a high TS to a low TS that's tricky to fix. I'm still thinking about the best way to handle this. There is a hack to work around it in my testing branch. This case can't happen on nanoBTS or BS-11 but it may happen on a real network. - TOA loop: I want to check if I can re-use the common code from our AFC/AGC loop rather than adding some other regulation stuff. - Enabling HR: Well ... it doesn't work yet, so no point in putting it in master :) All theses will be added when I have the time to do it. Cheers, Sylvain Munaut
