[[PageOutline]] = osmocon = Osmocon is a console tool for our baseband implementation. It is used to download a firmware or bootloader into the phone over the serial interface, which is currently implemented for the CompalE88 and the CompalE99. After uploading a firmware, it turns into an HDLC mux/demux, allowing multichannel communication with the device. The phones console is on one such channel and will be redirected to the terminal on which osmocom runs. Several other HDLC channels are accessible by means of the following unix domain sockets: * /tmp/osmocom_l2 for the [wiki:L1A_L23_Interface] * /tmp/osmocon_loader for the [wiki:Bootloader] == General Usage == * Connect your Compal phone to a serial port of your PC, using a [wiki:CalypsoSerialCable] (3.3V RS232 on 2.5mm headphone jack) * Determine what you want to run (see [wiki:Applications]) * Start the console osmocon program like this, filling in your phone type and binary path: this {{{ $ ./osmocon -m c123xor -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.ramload.bin /path/to/your/object_code.bin }}} * Push the power-on button of your phone (short push, not like a regular phone boot!) * Observe output resembling the following output: {{{ got 2 1 bytes from modem, data looks like: 2f c8 04 got 5 1 bytes from modem, data looks like: 81 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 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_e88/loader.ramload.bin): file_size=13404, hdr_len=4, dnload_len=13411 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 got 1 bytes from modem, data looks like: 02 got 1 bytes from modem, data looks like: 43 Received PROMPT2 from phone, starting download handle_write(): 1023 bytes (1023/13411) handle_write(): 768 bytes (1791/13411) handle_write(): 768 bytes (2559/13411) handle_write(): 768 bytes (3327/13411) handle_write(): 768 bytes (4095/13411) handle_write(): 768 bytes (4863/13411) handle_write(): 768 bytes (5631/13411) handle_write(): 768 bytes (6399/13411) handle_write(): 768 bytes (7167/13411) handle_write(): 768 bytes (7935/13411) handle_write(): 768 bytes (8703/13411) handle_write(): 768 bytes (9471/13411) handle_write(): 768 bytes (10239/13411) handle_write(): 768 bytes (11007/13411) handle_write(): 768 bytes (11775/13411) handle_write(): 768 bytes (12543/13411) handle_write(): 768 bytes (13311/13411) handle_write(): 100 bytes (13411/13411) handle_write(): finished 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 got 1 bytes from modem, data looks like: 03 got 1 bytes from modem, data looks like: 42 Received DOWNLOAD ACK from phone, your code is running now!
