2019-05-23[WIP] HO: Add RX only mode for handoverAndreas Eversberg1-0/+2
When establishing dedicate mode, a flag is used to disable transitter. When transmitter is disabled, access bursts are allowed. After sending a L1CTL_PARAM_REQ, the transmitter is enabled with given parameters. Change-Id: I43b14089e0b8988db6a73dd143c8ea806284ab7a
2019-05-23[WIP] HO: Add SCH read of neighbor cells to TCH channelsAndreas Eversberg3-0/+14
The task will try to sync to neighbor cell during search (idle) frame. Change-Id: I7f2c6b5438676a816c546cb9dce404762ee5d5b5
2019-05-23[WIP] HO: Add power measurement of neighbor cells to TCH channelsAndreas Eversberg2-8/+14
The task will measure power between TX and RX of successive TCH frames. Change-Id: I0c5a1714249799ff0f2031ca0585ec051c61cc6b
2019-05-23[WIP] Change TPU offset on TS change or sync changeAndreas Eversberg1-1/+3
When TPU offset must be changed (assignment to different timeslot or handover to a different cell), all tasks will be disabled until new TPU offset has been applied. Currently scheduled tasks are finished before the new TPU offset is applied. On change of TPU offset, the TPU's interrupt may skip one frame when changing backwards in time. Also it may generate two interrupts when changing significantly forward in time. This is compensated by changing the GSM time. Change-Id: If858484a9cf497e0f6e8d84593ab3637c2668869
2019-02-19firmware/lib: introduce TIFFS filesystem supportMychaela Falconia2-0/+36
All known TI GSM firmwares implement some kind of flash file system, or FFS. We call it TIFFS (Texas Instruments FFS) because it is TI's invention. TIFFS is a file system with a hierarchical directory tree structure, and with Unixy forward-slash-separated, case-sensitive pathnames; the semantics of "what is a file" and "what is a directory" are exactly the same as in UNIX; and TIFFS even supports symlinks, although that support is a little under-developed, and apparently no FFS symlinks were ever used in any production GSM device. Thus the FFS implemented in TI-based GSM devices (modems and "dumbphone" handsets) is really no different from, for example, JFFS2 in embedded Linux systems. The FFS in a GSM device typically stores two kinds of content: - Factory data: IMEI, RF calibration values, device make/model/revision ID strings etc. These files are expected to be programmed on the factory production line and not changed afterward. - Dynamic data written into the FFS in normal device operation: contacts, settings / preferences, call history, received SMS, etc. It should be noted that both Compal (Mot C1xx) and Foxconn (Pirelli DP-L10) vendors moved their vital per-unit factory data out of the FFS into their own ad hoc flash data structures, leaving their FFS only for less critical data. However, we do enable TIFFS access for them anyway. The location of TIFFS within the flash memory of a given GSM device is defined by the firmware design of that device, but is always some integral number of contiguous flash sectors. - On Motorola/Compal C139/140 phones, the FFS used by the original proprietary firmware occupies 5 sectors of 64 KiB each (320 KiB in total), starting at 0x370000. C11x/123 use smaller FFS configurations, whereas C155/156 seem to have switched to some other FFS format, different from our familiar TIFFS. - On the Pirelli DP-L10, the FFS used by the original proprietary firmware occupies 18 sectors of 256 KiB each (for 4.5 MiB in total), starting at the beginning of the 2nd flash chip select (0x02000000 in the ARM7 address space). - On FCDEV3B (FreeCalypso hardware), the FFS is located in the first 8 sectors (of 256 KiB each) in the 2nd flash chip select bank, which appears at 0x01800000 in the ARM7 address space. - On the GTA01/02 GSM modem, FFS occupies 7 sectors of 64 KiB each, starting at flash offset 0x380000. For more information, please refer to the FreeCalypso project documentation, from where this great contribution comes from. Please note that existing MediaTek targets most likely use different storage format as they have nothing from TI Calypso. Also, we don't (yet) know the location of TIFFS on SE J100i and Compal E99 targets. The TIFFS support is needed for the follow-up change, that implements reading of the factory RF calibration values.

2018-10-03firmware/layer1: add scheduler tasks for CBCHAlex Badea2-0/+5
According to GSM TS 05.02, section 3.3.5, Cell Broadcast Channel (CBCH) is a downlink only channel, which is used to carry the short message service cell broadcast (SMSCB). CBCH is optional, and uses the same physical channel as SDCCH. More precisely, CBCH replaces sub-slot number 2 of SDCCH channels when enabled. This change introduces the following CBCH related tasks: - MF_TASK_SDCCH4_CBCH (CBCH on C0/TS0 SDCCH/4), - MF_TASK_SDCCH8_CBCH (CBCH on SDCCH/8), which are identified using the following Osmocom specific cbits: - MF_TASK_SDCCH4_CBCH - 0x18 (0b11000), - MF_TASK_SDCCH8_CBCH - 0x19 (0b11001). The only way to enable these tasks at the moment is to send L1CTL_DM_EST_REQ message with required cbits and tn. Change-Id: I1d7f02cba1cd8f6527360589d2d2747b6426f78b
2017-01-15define 'fprintf(stderr,' as a wrapper around printf(Harald Welte1-0/+1
This is in preparation to work with a more recent version of libosmocore, which wants to print to stderr in some cases.

Only on BCCH's multiframe we are allowed to measure on frames 0, 10, 20, 30, 40. On SDCCH/8 multiframe, measurements are performed on frame 50 only.

5 measurements are now performed during a 51 multiframe. They are performed at one of the 5 FCCH. Additionally a timeslot offset can be given for each measurement. This way it is possible to measure each timeslot seperately. The given ARFCN must be in sync with the serving cell.

2012-01-29timers: comply with timer rename in libosmocoreHarald Welte1-11/+10
libosmocore has prefixed the timer functions with omso_* already in May 2011 (0b21c1c8850d7f33f55d9399d14055a7cdda3614), and we follow suit here for API consistency reasons.
2012-01-28target/rf: Make the trf6151_set_arfcn use ARFCN_UPLINK flag to select UL/DLSylvain Munaut1-1/+3
This way we can independentely control what frequency we want and wheter we want to TX or RX. This allow TX on DL band and RX on UL band. This also means all call to tx_window setup now need to properly set the ARFCN_UPLINK flag ! Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

2011-07-17[layer1] Adding neighbour cell measurement code to layer1.Andreas Eversberg3-0/+14

2011-07-17[rf] Adding rffe_set_gain() and rffe_get_gain() to get/set computed gainAndreas Eversberg2-4/+12
rffe_compute_gain() is the new name for rffe_set_gain(). I needed to change this, to solve the name collision with the rffe_set_gain() function, which actually sets the absolute gain. rffe_get_gain() will now read the absolute gain which has been computed by rffe_compute_gain() or set by rffe_set_gain().

2011-04-26src: use new libosmogsm and include/osmocom/[gsm|core] path to headersPablo Neira Ayuso9-10/+10
This patch changes include paths to get osmocom-bb working with the current libosmocore tree. Among all these renames, you can notice several tweaks that I added on purpose, and that require some explanation, they are: * hexdump() in osmocon.c and osmoload.c has been renamed to avoid clashing with hexdump() defined in libosmocore. * gsmmap now depends on libosmogsm. Actually I had to cleanup Makefile.am because I was experiencing weird linking problems, probably due to a bug in the autotools. With the change included in this patch, I got it compiled and linked here correctly. This patch has been tested with the phone Motorola C123 and the following images files: * firmware/board/compal_e88/hello_world.compalram.bin * firmware/board/compal_e88/layer1.compalram.bin Using the osmocon, bcch_scan and mobile tools.
