l1test hangs

Hi all, This weekend I had my first try with a C123, and everything seemed to work great from the start. But suddenly when uploading l1test.bin to the phone, it seems to hang after the first three ARFCN's found, like so: Hello World from apps/l1test/main.c program code ====================================================================== Device ID code: 0xb4fb Device Version code: 0x0000 ARM ID code: 0xfff3 cDSP ID code: 0x0128 Dropping sample '~' ============= Assert DSP into Reset Releasing DSP from Reset Setting some dsp_api.ndb values Setting API NDB parameters DSP Download Status: 0x0001 DSP API Version: 0x975b 0xadac Finishing download phase DSP Download Status: 0x0002 DSP API Version: 0x3606 0x0000 Performing power measurement over GSM900 LOST!ARFCN Top 10 Rx Level ARFCN   7: -102 dBm ARFCN  10: -103 dBm ARFCN  14: -103 dBm When I press any button of the phone it continues by showing the remaining ARFCNs, but nothing else: ARFCN  43: -103 dBm ARFCN  85: -103 dBm ARFCN  87: -103 dBm ARFCN 105: -103 dBm ARFCN 115: -103 dBm ARFCN 123: -103 dBm ARFCN  96: -104 dBm Starting FCCH Recognition key=12 pressed key=12 released I also noticed the dBm values, all channels are barely above the noise floor, right? Does anybody have tips on how to get running again? Thanks, Hessel
