nRF52832 Custom board designing on single side pcb

Hi, I'm designing nRF52832 custom board, on 'single side' pcb.

To make VDD and GND lines connect, I used 4 jumpers, which have 0 ohms.

I designed with nRF52832-QFAB reference layout and pcb layout for internal LDO setup, but little difference from pcb layout to make on single side pcb.

But for some reason, I cannot use this pcb when I connect it to my DK board, using Keil. Everytime I connect and loading the example code on it, I got this error message.

I am absolutely have no idea what is the problem for this error, since with double side pcb with reference layout and pcb layout from this Nordic, there was no error like this.

Hope anyone can tell me what brings that kind of error. In my opinion, its because of soldering problem or the design problem, since same code is work for double side pcb.

Any recommends for the design or error will be very appreciated for me. Thank you.

  • The error message shows up when I connect my custom board to my DK board with this configuration.

    DK board                                                 Custom board

    VDD, VTG  -------------------------------->          VDD

    GND ----------------------------------------->          GND

    SWDIO -------------------------------------->          SWDIO

    SWDCLK ------------------------------------>          SWDCLK

    As followed the recommendations in error message, I got log file(inserted on this reply) but still have no idea what brings this problem.

    Also, trying to find out how to using Segger tools and scope my power supply to check drooping.

  • Remember that we can't see what you're doing - you have to explain clearly, completely,  and in detail!

    The error message shows up when I connect my custom board

    What, exactly, do you mean by "connect"

    • physically plug things together ?
    • try to launch a connection in your IDE ?
    • other ??
  • You didn't follow the suggestion on how to post it so it's legible.

  • Sorry for my ambiguity.

    First, I connect my DK board with my PC. Then physically connect the VDD, VTG, GND, SWDIO, SWDCLK pins in DK board to my custom board. After that, I started programming from command 'nrfjprog' and Arguments '--family nrf52 --eraseall --log'.

    I will check the suggestions you tagged. Thanks again.
