I cant seem establish a connection to the javelin through the usb port on the PDB.· it works with a BS2p and it works· when i use the usb to serial adapter and 9 pin programming port (meaning the jide will detect it..still get error 6 when trying to load program). I changed the latency down to one for that port and i have downloaded and reinstalled the driver.·· any ideas?

    According to the error code documents, IDE code 6 is
    Could not open the serial port %s: The serial port could not be opened.
    [font=Arial,Arial size=2]Make the serial port is not already in use by another program.
    [/font]
    So it looks your usb driver keeps the port open. Close down all applications that use that
    port, perhaps even reset pc, then try again.
    But first check if your com port is listed in the IDE.
    In the IDE, go to Projects->Global options
    Tab Debugger, then edit port list (click ... next to droplist)
    Then try it, if it does not work, try resetting the pc.

    Peter......first of all i won the pool that said you would be the first to respond....thanks...i get lunch today. This is what puzzles me....I also have a super carrier board and when i use it in conjuncion with the usb to serial adapter, everything works fine. other than my mouse there are no other usb devices or programs using usb. it is begining to look like there is a firmware difference between the usb to serial adapter and the pdb. have you heard anything about firmware changes?

    I do recall there was a thread in another forum regarding the PDB usb connector.
    The poster there hoped it would not be the FTDI chip used on the PDB that
    caused the errors. I can't seem to find that thread now, but I am positive it
    was the SX forum, or the Sandbox.
    But as I understand you, you can program the javelin using a seperate usb2ser cable
    or the serial cable, right?

    That is correct, however, only when using the super carrier board. when i use the usb to serial adapter on the pdb the jide will identify the javelin but when i try to download the program i get error #6.

    Gentlemen,

    ·· The PDB does support the Javelin through the USB Port for programming.· The Javelin IDE, however, does not support COM Ports above 4, as I recall.· What COM Port was assigned to the USB interface?· If it was higher, try setting to a COM Port below 5.
