Hello, I have managed to compile everything, I connected my phone trough USB but when I try to run ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin I do not get the " Received PROMPT1 from phone, responding with CMD" message All I get is this: root@ubuntu:/home/trepx/osmocom-bb/src/host/osmocon# ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin got 2 bytes from modem, data looks like: f1 06 .. got 5 bytes from modem, data looks like: 72 82 bf 7d fd r..}. 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: 00 . got 1 bytes from modem, data looks like: a6 . 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: 02 . got 1 bytes from modem, data looks like: 4d M got 1 bytes from modem, data looks like: da . root@ubuntu:/home/trepx/osmocom-bb/src/host/osmocon# ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin got 2 bytes from modem, data looks like: f1 06 .. got 4 bytes from modem, data looks like: a6 51 d2 51 .Q.Q 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: 00 .
