Dm 7000s bootet nicht mehr hoch

Wir haben aktuell ein Problem mit dem Board und arbeiten an der Lösung...

    Hi,


    first try to put the “erase image” with Dreamup and serial connection on your box.
    You will find the image in our database (Images DM7000, Sonstige Images).
    Than you can flash a new image.


    Regards Thomas

    Thank you for the help and for all this members of this forum who want’s to REALY help and SHARE information’s..instead of this “experts” who perhaps understand what is happened???? This is real nature of this few people…sad!


    I try this method with erase image, with same result: ” Flash-erase FAIL”. The dreamup send the image to flash and at the finish try to erase the old flash installed and he can’t erase.
    This is my problem…can’t erase flash.

    ibm-iic1: xfer error, EXTSTS = 0x43

    I read the Atmel with AVRISP and AVR Studio, I read the flash and eeprom, and something wired was happen , the box continuous restarting over and over.
    I look in the this file and all was zero…
    Fuses 0xD9 0xA4, Signature Byte 0x1 0x93 0x07


    Are possible to find the dump for this Atmega8?

    Update status...I’ve fuck the Atmel...I can't read/write....
    From where I will buy a new preprogramed Atmel?
    Regards,

    it must be de-soldered?, it's not possible to write directly?
    Thank you for the helping...
