    2. win10,codewarrior v10.7, Driver(Cyclone/TraceLink,pemicrowindrvr)

    problem: cant connect target(codewarrior target setting has nothing)

    • Hi Liang,

      Sorry for the late reply. Would it be possible to take a screenshot of this specific error and send it in a Support Request so we can take a further look?



      • Hi Steve,

        The problem was sovled.Thanks,because jumpers are not set correctly.

        But,our board powers the MCU. don't need the cyclone to power the MCU. Why ca n't download? And I tried all the jumper ways.

        Does cyclone need to configure something???

        • Hi Liang,

          You have to make sure that the TVCC pin from the Cyclone to your target device is connected as well. Another common issue is a hardware reset or external watchdog is being activated during this process at some time.

          I would measure the TVCC pin going to connecting from your target device to the Cyclone and see what voltage you are getting there. I would also try probing the RESET pin and make sure that it is not being activated during the erasing/programming process.
