Not responding Javelin

Hello again,

After some programming the Javelin Stamp IDE gave the following errors:
Linking
Finding Javelin
[noparse][[/noparse]Debug] Discarding packet
[noparse][[/noparse]Debug] Discarding packet
[noparse][[/noparse]Error IDE-0056] Possible Javelin on COM5 did not respond.
[noparse][[/noparse]Error IDE-0054] Unable to find a Javelin on any port.

Robot Freak, a friend, had the same problems some time ago.

So, I also tested it with Primejavelin, and get the same errors he gets.
I'm also using the USB Board of Education.
His Board and Javelin are working on the same port, computer and with the same battery.

Does this mean I've got to send it back, like he did?

Thanks!

    Ervie,

    Are you using a serial or USB interface? How are you powering the Javelin?

    We use a Board of Education-USB, and connect it directly to the computer with a USB-A to USB-B cable.
    The usb to serial drivers are installed.
    We are powering it with a 9V battery, directly on the Board of Education.
    The latest programmed program runs, but·now programming·won't work.

    When using "Identify" the following fields appear:
    Device Type: [noparse][[/noparse]empty]
    Version: $50
    Loopback: Yes
    Echo: Yes
    Got Status: No

    Hello,

    A 9V battery does not provide sufficient current for the Javelin. This may be part of your problem.

    I connected the Javelin with the same 9V battery, the same USB cable and it works!
    Then I downloaded again I got one discharging message, and then downloading started.
    So, the current is the problem. Can I connect 2 9V batteries parallel?

    Thanks,
    Ervie

    I wouldn't connect 2 batteries in parallel.
    Get yourself either a 9V or 12V 1A AC/DC power supply
    or a 7.5V/1A accupack with recharger.

    regards peter

    We made a mistake. The 2times working Javelin was my friends.
    Mine isn't working, it's giving the same errors and also when using wall power supply. (7.5V/1A)
    His Javelin works with the same power supply, same computer and same USB cable.
