    Default Carprog MCU Reflash problem

    Hi. I tried to reprogram my carprog, but without succes.
    The first time I removed the memory from the board. Then I reset the MCU with pin 55 to + 3.3v for 20 seconds. After I connected pin 55 to GND. When I click detect, it does not find it.(I use J-link v8)
    Can someone help me? I have attached some images with the connections. Thanks !

    You can use this diagram without Jlink interface. Work OK. carprog.jpg
    Rremember use the very short wires for conect. Max 6 Cm.

    it doesn't matter how long the wires are.leave more time connected to 3.3V, the reset can take more than 20 seconds.when you try to connect to the processor, pin 55 must be disconnected, only after you finish programming you put it to GND.

    alot of carprogs are bought with very old firmware and everyone wants the carprog with at least fw 8 inside therefore reflashing with fw8 dump makes it better
