nRF52832 Flash_fds example

KCY

Hi, 

I am using nRF52832 mcu, trying to run the flash data storage example but is having some trouble.

I followed the instructions to set up the terminal setting for UART using PuTTY, but nothing happens when I click on OPEN. I am using the newest version for PuTTY. Is there any setting that I might also have to change other than those specified in the instructions?

Thank you!

    Hi Terje,

    Yes, I am just testing with the unmodified example right from the SDK.

    These are the pages in PuTTY configurations which I have changed according to the document.

    Thank you for your patience!

    Hi,

    Yes, everything seems to be in order there.

    It may be an issue with data left in flash from a previous application? You can check that by doing a full erase of the flash before programming the board. Use either nrfjprog ("nrfjprog -e" on command line) or the nRF Connect Programmer app ("Erase all" button).

    How is the DK connected to the PC? Is it via a USB hub, or docking station, or directly in a USB port on the PC itself? Can you try different USB ports to see if there may be an issue with the particular USB port?

    Regards,

    Sorry, My nRF52-dk stopped working all of a sudden and I can't fix it :/ The LED doesn't light up when I plugged it in. Just for the record, the dk was connected directly in a USB port on the PC.

    Is there a way for me to test out the example without the dev kit? I have a JTAG/SWD Debugger Programmer that I can upload the code with, but I don't think I can use Serial communication anymore?

    Hi,

    I am sorry to hear about the board. Do you have any other boards or dongles that you can try with? For using the serial CLI you would need a UART or RTT connection to the SoC, both of which are provided by the programmer MCU on the DK.

    Regarding the now non-working DK, was it a brand new DK or has it been used a lot? Are there any solder bridges that have been cut or soldered, etc? What are the markings on the DK? (PCA10040, etc.)

    You could try to download the latest interface firmware to the programmer MCU on the board, have a look at the DK User Guide for how to.

    Regards,
    Terje
