Asking how to load firmware on Holyiot nRF52832 dongle

[Paul Bradford]

I got some Holyiot "YJ-17017-USB" dongles, which use the nRF52832. From my Windows dev environment, I want to load firmware on them (SoftDevice, etc.), but I'm not sure how. The datasheet has a Programming section
    www.holyiot.com/.../2019042318312862317.pdf
    "Holyiot-17017 module use the Serial Wire Debug(SWD port )"

I looked at the Serial Wire Debug document linked there: https://www.silabs.com/community/mcu/32-bit/knowledge-base.entry.html/2014/10/21/serial_wire_debugs-qKCT

That doc talks about a “2-pin” interface, but the "YJ-17017-USB" has a USB connection with no exposed pins at all, so I don’t understand how SWD can apply to the "YJ-17017-USB".

My background: I'm very new to working with Nordic products. I started working with the nRF52 series this month, and successfully did some testing with the Nordic nRF52840 dev-dongle, programmed via nRF Connect with a pre-built firmware file.

Thanks,

Paul

Hi.

As awneil said below, you should contact Holyiot for specific details about their product since Nordic does not have information about this :-)

Best regards,

Andreas
