Now I ran the osmo-nitb, osmo-bts-trx and osmo-trx all together with the USRP2 with FLEX900 daughter board GSM900 band, it all works well except the mobile is not able to register on the network.

I haven't looked at your error logs in detail, this is just what comes to mind:

Response speed may be an issue. Hopefully the pi is fast enough, and maybe try to run osmo-bts-trx -r 1 and osmo-pcu -r 1 for real-time priority (may need sudo).

Also, the timing source for the SDR may be an issue. I am told e.g. the B200 is known to be unreliable without a quality timing source, and results improve with a proper 10MHz clock connected.
