Hello Andreas
1. As you mentioned use OpenBSC -> master and OsmoBTS -> jolly/trx branch. Compiling OsmoBTS results in compilations errorrs.
Log from OsmoBTS:
rsl.c:138:2: warning: #warning merge lchan_lookup with OpenBSC [-Wcpp] rsl.c: In function ‘rsl_rx_chan_activ’: rsl.c:744:53: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c:748:15: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c: In function ‘rsl_rx_mode_modif’: rsl.c:991:53: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c:995:15: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c: In function ‘rsl_rx_ipac_XXcx’: rsl.c:1304:7: warning: passing argument 3 of ‘osmo_rtp_get_bound_ip_port’ from incompatible pointer type [enabled by default] /usr/local/include/osmocom/trau/osmo_ortp.h:71:5: note: expected ‘int *’ but argument is of type ‘uint16_t *’ make[2]: *** [rsl.o] Error 1 make[2]: Leaving directory `/home/cinterion/alt_cint/osmo-bts/src/common' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/cinterion/alt_cint/osmo-bts/src' make: *** [all-recursive] Error 1
2.
No errors when OpenBSC -> jolly/testing and OsmoBTS->jolly/trx. But cannot start OsmoSGSN when OpenBSC is on Jolly/tetsing.
OsmoSGSN says :
<0010> gprs_ns.c:171 NSVCI=65534 Creating NS-VC <000f> sgsn_libgtp.c:571 Failed to create GTP: -1 <000f> sgsn_main.c:346 Cannot bind/listen on GTP socket
So after compiling OsmoBTS, I switch OpenBSC->master and then start OsmoSGSN and it starts.
Then OsmoSGSN says : <0010> gprs_ns.c:171 NSVCI=65534 Creating NS-VC
3.
I was able to connect the PCU to OsmoBTS... I compiled PCU with sysmo-bts support then it connected to osmoBTS. I could also use the second phone for TS1 and was able to send a IMM ASS (for packet channel). I verified this on the MS (requesting for GPRS attach). And by observing log from PCU it shows MS has responded in TS-1 and sent data.
OsmoNITB is also working good.

After this OsmoBTS results in
Segmentation fault (core dumped)
Can you please tell how can I compile OsmoBTS correctly by using OpenBSC->master.

Hello andreas,
thanks a lot for your help.
I resulted successful in running the osmoBTS with calypso phones. Currently I did (register) with 1 phone but will do it with 2 also. yes I am using the debugging option.
Can you kindly tell me how should I enable the PCU support. I have the osmo-pcu (master) installed and I start it before starting osmoBTS.
I tried to use jolly_test in osmo-pcu git, but errors concerning sysmobts.
I tried looking around sockets and vty but could not figure it out. I looked at the osmo-bts-sysmo code which has the command line option (-M --pcu-direct) to enable pcu support. I looked at the code and I found that pcu_direct is set to 1 (pcu_direct=1) when -M option is used.
using this as a reference in the main.c of osmo-bts-trx i directly defined pcu_direct=1 and then tried. The socket /tmp/pcu-bts is open but still I dont see any response from PCU.
Can you suggest me in this regard.
regards,
Altaf

Yes, I understand how trx uses two phones by reading your previous commits. I will study them

ok. Thank you...
I will look into this and will post if any success..
You say that using jolly/testing branch it is possible to use two phones. I am not sure how to use two phones and connect and how is the sync b/w them. Can you please give some brief idea before you write documentation.
isnt it possible with 1 phone, Just for minimal functions.?
I don't find the branch jolly/trx in git clone git:// github.com/chemeris/openbts-p2.8.git. Should I clone from a different git.

PCU -> master bts -> gprs-work os_BB -> sylvain/testing openbsc -> master
pcu master is ok (everything merged). openbsc master is ok. bts gprs-work? i don't know this branch, please use jolly/trx. osmocom_bb you should use jolly/testing branch, because you need to use two phones, one for broadcast and one for timeslot 1 (gprs). i think i need to write a documentation for that. but in your case, the IMM.ASS problem must be solved first.
