Hi Andreas,

Thanks for your suggestions ...

Below is the output after loading the layer1 to mobile

OsmocomBB Layer 1 (revision osmocon_v0.0.0-1747-geeafd9f-modified)
======================================================================
Device ID code: 0xb4fb
Device Version code: 0x0000

======================================================================
Power up simcard:
Assert DSP into Reset
Releasing DSP from Reset
Installing DSP extensions patch
Setting some dsp_api.ndb values
Setting API NDB parameters
Finishing download phase
DSP Download Status: 0x0002
DSP API Version: 0x3606 0x0000
LOST 7089!

and i am able to see the layer 1 osmocom-bb in the mobile.

As per your suggestion i checked with bcch_scan

here is the output snippet from the console of ./bcch_scan

arfcn=853 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=870 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=876 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=877 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=881 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=882 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=885 rxlev=1
<000c> l1ctl.c:118 FBSB RESP: result=255
arfcn=-1 rxlev=0

It goes on like this and finally ends with negative value.

and in osmocon console the output is like

Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=849, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=853, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=870, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=876, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=877, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=881, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=882, flags=0x7)
Starting FCCH RecognitionL1CTL_FBSB_REQ (arfcn=885, flags=0x7


by this i assume that my mobile is not able to sync with the network
..please correct me if i was wrong...


and also kindly assist me for any kind of modifications.

thanks in advance

Regards,
Cris
