Flashing the Dev Board

NoteFlashing the Dev Board erases any existing app, as well as any installed kits, and installs the factory-shipped “jenDbDemo” app and “jenFallback” fallback app. If you have done any previous work with the Dev Board that you wish to retain, make a backup before flashing the Dev Board’s firmware. For details, see Making a backup.

To flash the Dev Board, you must connect the included serial cable to the Dev Board’s DB-9 serial port. At the PC end, connect this cable to either the included FTDI “USB to RS-232” adapter, or if a standard DB-9 serial port is available, directly to that COM port.

NoteClose down any other program using that PC COM port, including any serial terminal program.

To flash the Dev Board

  1. In Sedona Workbench, open the Jennic Serial Port Tool (Tools->Jennic Serial Port Tool).

  2. For the COM Port cabled to the Dev Board, click its Type and change from unknown to flasher.

    A “Firmware Archive” entry field appears below the Ports table.

  3. Click the folder icon to open the Firmware Archive dialog, with default path of:

    Drive: / Sedona/SedonaWorkbench-1.0.47 / sedona

  4. The file needed is !/sedona/jennic/firmware/firmware-DR1105.zip

    Navigate to this by clicking on the folders jennic and firmware, as shown in Figure 59.

  5. Double-click the firmware-DR1105.zip file, or with it selected click Open.

    The Firmware Archive dialog closes and the Flash button becomes enabled (Figure 60).

  6. Click the Flash button.

    A JenFlasher dialog reminds you to first put the device in program mode, as shown in Figure 61.

    NotePut the Dev Board in program mode: hold down pushbutton PROGRAM (SW7) and push RESET (SW5).

  7. After putting the Dev Board in program mode, click OK. A Flash dialog appears during the download.

    LED activity on the Dev Board stops during the flash firmware download.

  8. When the Flash dialog disappears, press the Dev Board’s RESET (SW5) pushbutton. This restarts the downloaded app, which should cause LEDs D1 and D2 on the Dev Board to alternately toggle on and off.

  9. In the Jennic Serial Port Tool, return the COM port’s Type from flasher back to unknown.

You should now be able to open a Workbench sox connection to the Dev Board, as described in the procedure Open Sedona dev board with sox connection.

Figure 63 shows an example connection to a Dev Board that had firmware just flashed.

Note that when you open the Dev Board, the Sox Manager shows the installed kits at the latest release level, matching the release level of the Sedona Workbench.
