    Alain,

    Your chip is a D0 Silicon version. (Same date as Melanie).

    If I am the winner of the day, Microchip is the loser of the day because
    they will have to add this workaround also in the Errata Silicon D0 document.

    Glad to hear that things are moving forward!

    Best regards,

    Luciano

    Angry One more BUG ...

    It was rather difficult to program the chip ... W/ my Picstart

    I cleared my program from " double writings " ...

    Now, it's become impossible to re-program the chip ...

    only config can be entered at the THIRD try ...

    EEPROM at the first ...

    All the program memory is read as FF ...

    ERROR ...ERROR ... ERROR ....

    Trash BOX !!!

    Hi,

    See this link:
    http://www.microchip.com/stellent/id...&part=UK003010


    The PICSTART® Plus Flash Upgrade Module (PUM) is a PCB that contains
    a PIC18F6720 device that has been programmed with the firmware needed
    to provide support for a specific set of devices in the MPLAB® IDE.

    My comment:
    The PIC18F6720 device is the "workarounds" container.

    Luciano, Workarounds container? Whats that all about? I have used my PUM for about a year or so with no dificulty. I have put it aside however because Microchip doesn't support all of there processors on it. I now use the ICD2 which supports all of there processors and I probably will never go back.

    ICD-2 is a great programmer, far better than PICSTART for less money
    PICSTART is a fair to good programmer. Got once a problem with the PUM. ICSP support is fair to good... BAD in few ocvcasion too.

    The best investement i did is my BK Precision 844A (a relabeled of XYZ Elnec programmer) That's an universal programmer support is lifetime Free of charge and works like a charm ICSP or not. So last week i trash my Picstart and ICD-2, wich i consider now as a pure waste of money AND Even if an ICD could, in rare occasion, handy. There's so many other method to do serious DEBUG instead of using ICD.

    Sure BK-844A is much expensive but do more than only PIC

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
