| 3 | Using compal_dnload on your (Linux) PC, you can download arbitrary object code into your Compal-made Calypso-based phone. |
||
| 4 | |||
| 5 | == Usage == |
||
| 6 | |||
| 7 | * Connect your Compal phone to a serial port of your PC, using a [wiki:CalypsoSerialCable] (3.3V RS232 on 2.5mm headphone jack) |
||
| 8 | * Start the compal_dnload program like this |
||
| 9 | {{{ |
||
| 10 | $ ./compal_dnload /path/to/your/object_code [ /dev/ttyUSBn ] |
||
| 11 | }}} |
||
| 12 | * Push the power-on button of your phone (short push, not like a regular phone boot!) |
||
| 13 | * Observe the following output: |
||
| 14 | {{{ |

| 76 | == Known Problems == |
||
| 77 | |||
| 78 | Somehow we're not always getting the timing quite right. If you never get the PROMPT2 or DOWNLOAD ACK, you might |
||
| 79 | be affected by this bug. |
||
| 80 | |||
| 81 | The bug seems to resolve around the following line in the source. Try to comment it out and recompile: |
||
| 82 | {{{ |
||
| 83 | /* write some dummy character that is not used */ |
||
| 84 | write(serial_fd, &running_xor, 1); |
||
| 85 | }}} |
||
| 86 | |||
| 87 | Any additional help to resolve this bug is mostly welcome! |
