mt6516
by Marius Cirsta 14 Feb '11

Hi Does anyone have any info on Mediatek MT6516 ? I'd like to take a look at a datasheet if possible and I also know Android had been ported to it. Any chance of some open source code being released by Mediatek ? Thanks.

I have three of PK168+ Mediatek 6325. Is it possible to use these?

sounds quite interesting, but is it even possible to run osmocombb natively without host and target program (thus with connection to a pc/notebook)? azet -- "I have no certainties, at most probabilities." -- Renato Caccioppoli

Pirelli DP-L10 support for burst_ind
by Mad 13 Feb '11

13 Feb '11

Hi Sylvain, hi Steve, hi list! I did some kind of backport of Pirelli DP-L10 support for the burst_ind branch, patch attached. Remember that after applying you still have to swap the UARTs as mentioned in the wiki to maintain compatibility with the usual configuration in compal phones. The convenient thing with using the Pirelli with burst_ind is that it works out-of-the-box at high serial speed using its standard usb cable (without 2.5 jack to serial to ftdi-usb constructions). But there is one issue I came across with layer23, after a short time of normal operation when returning from DCH to CCH it just gets stuck. The FBSB request returns 255 as result so I guess the fw was not able to resyncronize. When a new request is made by restarting layer23, it works again for some time. Perhaps it has something to do with the used calibration values like SYSTEM_INHERENT_GAIN for the gain control etc. which could be different with the Pirelli layout? BTW, Sylvain, will there be an integration of burst_ind functionality into the master branch at some time, do you have some plan for this? Regards, Mad

FCCH and SCH
by list_mailing 10 Feb '11

10 Feb '11

Hello, I'm newbie to osmocomm and GSM too....I'm studying the protocol and the source code...but I have many doubts...the first one is the following: 1. Which are the routines handling FCCH and SCH in osmocom source code? 2. When I load layer1 firmware and load mobile app, FCCH and SCH are automatically handled by this application? Sorry if my questions are stupid for you, but it's a litlle bit complicate moving in the code, above all for a newbie. Thanks in advance. -- View this message in context: http://baseband-devel.722152.n3.nabble.com/FCCH-and-SCH-tp2363201p2363201.h… Sent from the baseband-devel mailing list archive at Nabble.com.

I think we can start by moving the stuff step by step into the phone, if anyone wants to work on this, it would be much appreciated. Layer2 (LAPDm) should be relatively simple, but starting from RR/MM/CC and the cell reselection I expect some more difficulties...
