[[PageOutline]] = osmocon compal_dnload = Using osmocon compal_dnload on your (Linux) PC, you can * download arbitrary object code (such as the osomcomBB apps) into your Compal-made Calypso-based phone, using phone. It uses the protocol described at [wiki:CompalRamloader] * establish HDLC multiplexed communications channels with the software on the phone * /tmp/osmocom_l2 is the socket for the [wiki:L1A_L23_Interface] * the terminal itself acts as sercomm console to read text messages generated by the phone get object code downloaded and executed in your phone. == Usage == * Connect your Compal phone to a serial port of your PC, using a [wiki:CalypsoSerialCable] (3.3V RS232 on 2.5mm headphone jack) * Start the osmocon compal_dnload program like this {{{ $ ./osmocon ./compal_dnload -m c123xor -p /dev/ttyUSB0 /path/to/your/object_code.bin }}} * Push the power-on button of your phone (short push, not like a regular phone boot!) * Observe the following output: {{{ got 1 bytes from modem, data looks like: 04 got 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 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 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! }}} * Observe further output of the serial port generated by the code you have downloaded {{{ Hello World from C program code ====================================================================== Device ID code: B4FB Device Version code: 0000 ARM ID code: FFF3 cDSP ID code: 0128 Die ID code: 6397191EFA039BE7 ====================================================================== REG_DPLL=2002 CNTL_ARM_CLK=F081 CNTL_CLK=FF51 CNTL_RST=FFF7 CNTL_ARM_DIV=FFF9 ====================================================================== REG_DPLL=2193 CNTL_ARM_CLK=F081 CNTL_CLK=FF51 CNTL_RST=FFF7 CNTL_ARM_DIV=FFF9 ====================================================================== Releasing DSP from Reset Loading initial DSP bootcode Releasing DSP from Reset Setting some api_ndb values Setting API NDB parameters DSP Download Status: 0001 DSP API Version: 0DC4 6308 Finishing download phase DSP Download Status: 0002 DSP API Version: 3606 0000 }}} == Known Problems == For some USB-Serial converters (most notably FTDI based cables), you might need the {{{-m c123}}} mode, not the {{{-m c123xor}}} mode.
