Tomas Kopsa deacon at volny.czHello, I have C115 too and I use '-m c123xor' switch, the phone mostly boots on 1st button push (I never reacher full load with '-m c123'). ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/hello_world.compalram.bin ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/layer1.compalram.bin I have FTDI USB<->RS232 + Calypso serial. When load fails (with xor), I have a feeling that it helps reconnection cable to the phone. (I have also Calypso USB cable which I haven't tested yet, will report later.) - Tomas > Hello. > I'm trying to load the loader.compalram.bin. > The behaviour is very strange because sometimes the download is complete and > successfull, sometimes; in particular, in this case, the download is complete, > but any ACK is sent back from the mobile phone (see below). > ./osmocon -p /dev/ttyUSB0 -m c123 ../.. > /target/firmware/board/compal_e99/loader.compalram.bin > got 2 bytes from modem, data looks like: 2e c8 .. > got 5 bytes from modem, data looks like: 1b f6 02 00 41 ....A > got 1 bytes from modem, data looks like: 01 . > got 1 bytes from modem, data looks like: 40 @ > Received PROMPT1 from phone, responding with CMD > read_file(../../target/firmware/board/compal_e99/loader.compalram.bin): > file_size=21752, hdr_len=4, dnload_len=21759 > got 1 bytes from modem, data looks like: 1b . > got 1 bytes from modem, data looks like: f6 . > got 1 bytes from modem, data looks like: 02 . > got 1 bytes from modem, data looks like: 00 . > got 1 bytes from modem, data looks like: 41 A > got 1 bytes from modem, data looks like: 02 . > got 1 bytes from modem, data looks like: 43 C > Received PROMPT2 from phone, starting download > handle_write(): 4096 bytes (4096/21759) > handle_write(): 4096 bytes (8192/21759) > handle_write(): 4096 bytes (12288/21759) > handle_write(): 4096 bytes (16384/21759) > handle_write(): 4096 bytes (20480/21759) > handle_write(): 1279 bytes (21759/21759) > handle_write(): finished > > > The target phone is C115.
