Osmocon failed to flash

Hello, I'm newbie and want to learn about osmocombb. I already compiled all of the programs, but when I try to upload helloworld program, it stuck on this error $ host/osmocon/osmocon -p /dev/ttyUSB0 -m c123xor target/firmware/board/ compal_e88/hello_world.compalram.bin -c got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: f7 . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 72 r got 2 bytes from modem, data looks like: 82 bf .. got 1 bytes from modem, data looks like: 7d } got 1 bytes from modem, data looks like: fd . got 1 bytes from modem, data looks like: 7f . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: a6 . got 1 bytes from modem, data looks like: 51 Q got 1 bytes from modem, data looks like: d2 . got 1 bytes from modem, data looks like: 51 Q got 1 bytes from modem, data looks like: 0a . got 1 bytes from modem, data looks like: 3a : got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 4d M got 1 bytes from modem, data looks like: a3 . got 1 bytes from modem, data looks like: a3 . got 1 bytes from modem, data looks like: da . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 00 . I don't know if it hardware problem, or software problem. When I try to debug using putty to listen to /dev/ttyUSB0 there is no fmttool erro just like this article said http://www.linuxx.eu/2014/09/osmocombb-hardware-and-software-setup.html Regards.
