CalypsoBTS no sync, ms hang

Dear colleagues, I am trying to setup CalypsoBTS with two c113 phones. Don't you know why can't I sync to any commercial cell with transceiver from branch jolly/testing? What I have: Motorola c113 and c113a, tried both. All other apps like, RSSI, mobile, ccch_scan works like a charm. What I am doing: Built jolly/testing according to maual https://osmocom.org/projects/baseband/wiki/CalypsoBTS Load firmware ./osmocon -r 99 -m c123xor -p /dev/ttyUSB0 -c ../../target/firmware/board/compal_e88/trx.highram.bin Found several strongest cells with RSSI and cell_log. Trying to sync: ./transceiver -a 50 -r 99 -e 1 Here is the log: 50 41 1 <000c> l1ctl.c:77 Tx Reset Req (1) <000c> l1ctl_link.c:171 Sending: '0d 00 00 00 01 00 00 00 ' <0012> l1ctl.c:383 Reset received: Starting sync. <000c> l1ctl.c:95 Sync Req <000c> l1ctl_link.c:171 Sending: '01 00 00 00 00 32 00 64 27 10 03 20 03 07 00 00 00 ' After that phone hangs, no reaction in osmocon on key pressures, holding on power off button... The last messages are: L1CTL_RESET_REQ: FULL!L1CTL_FBSB_REQ (arfcn=50, flags=0x7) Starting FCCH RecognitionFB0 (2515:4): TOA= 3552, Power= -64dBm, Angle= 1328Hz FB1 (2525:8): TOA= 8543, Power= -64dBm, Angle= 114Hz fn_offset=2523 (fn=2525 + attempt=8 + ntdma = 6) delay=8 (fn_offset=2523 + 11 - fn=2525 - 1 scheduling next FB/SB detection task with delay 8 =>FB @ FNR 2523 fn_offset=2523 qbits=3988 Synchronize_TDMA LOST 3398! I tried different cells, maybe I need to wait some time to warm the crystal? But can it be so important? Kind regards, Anton
