PGA411Q1EVM: Device State: Reset N/A

Part Number: PGA411Q1EVM

As stated in the title, I'm getting a device state of "Reset N/A."  Not "Normal" or "Diagnostic."  I've tried resetting the EVM board and the GUI many times, but I keep getting the same device state.  Is there a fix for this?  Thanks!

    Stephen,

    Thank you for reaching out to us. On the opening page of the GUI under "EVM Status", can you list what it says? (or include a screenshot)

    USB Controller:
    Connection Status:
    USB Firmware:
    PGA41x-Q1 Device:

    Also, before you open the GUI, make sure that the D12 LED on the EVM is solid and not flashing. If it is flashing, then press the MCU_RST button on the EVM until the LED stays solid; then open the GUI.

    Clancy,

    I won't have access to the EVM until later tonight or tomorrow, but I can tell you that a connection between the board and the GUI was established. The USB Firmware was a valid number (not blank or 0.0.0.0). I'm not sure about the rest of the list.

    While a connection was established, the D12 LED on the EVM was solid.

    Something odd that I noticed last night was that when I told the GUI to drive the NRST pin low, my meter read ~4.8 V at that pin. When high, it read ~5.2 V. I'm starting to come to the conclusion that something is broken.

    Thank you for your help,
    Stephen

    Stephen,

    Did you double check the default jumper settings (you can see this in the user's guide)? I have seen the board vendor mix up the jumpers before, so please double check.

    Thanks,

    Clancy,

    Yes, we actually had the board working for awhile. We left the board alone for about a week, and when we came back to it, it was doing this.

    Regards,
    Stephen
