Frimware problem

Hello, I am working with a project Osmocom-bb. I did compile the project. But when the firmware command : ./osmocon -p /dev/ttyUSB0-m c123xor ../../target/firmware/board/compal_e88/hello_world.compalram.bin screen is just hangs (the power button I also click) , or most likely expects to input a sequence of bytes, i.e., no information no longer appears. The phone is switched on. I used this instructions for checking the operation of the http://lists.osmocom.org/pipermail/baseband-devel/2011-August/002230.html . 1) I use the FTDI cable, it is OK. Port is OK. 2) Note : I don't see FMTTOOL ERROR (!!!) when i press the power button. I tried the next model C113,C115,C118. Why this may happen? Thank you!
