Using compal_dnload on your (Linux) PC, you can download arbitrary object code into your Compal-made Calypso-based phone.

It uses the protocol described at [wiki:CompalRamloader] to 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 compal_dnload program like this {{{
$ ./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: {{{

}}} Known Problems

For some USB-Serial converters (most notably FTDI based cables), you might need the {{{-m c123}}} mode, not the {{{-m c123xor}}} mode.
