Cant use nRFGo Studio or RF Connect with nRF52840 Dev kit?

Hello, I’ve purchased the nRF52840 Micro Development Kit. I plug it into the USB port on my PC, and I can’t seem to see it from either nRFGo Studio or RF connect running on my PC. (These are the tools we use to program softdevice and binary on parts ordered from Nordic.)

Is there a reason these tools cant program this device?

Thanks.

Hi there,
The nRF52840-MDK comes with built-in DAPLink debugger which is open-source and easy to program and debug the chip.
Here is the tutorial for getting started:

Thank you. On that link they describe programming the chip by dragging and dropping the firmware (after merging it with the softdevice).

Is actual debugging (tracing execution, breakpoints, etc) possible?

Yes, you can debug your code via DAPLink. There are some tutorials you can follow:


Pitaya Link is a separated debug probe from nRF52840-MDK, so they have the same usage: https://wiki.makerdiary.com/pitaya-link/

Hi Zelin,
I have been able to program Nordic’s nRF firmware through drag-and-drop as well as the pyocd command line tool, but the nRF Connect suite of tools still does not recognize the nRF-52-MDK board as a Nordic USB device. Is there any way to resolve this? Clearly DAPLink is a fast and convenient way to program, but using it seems to be preventing the use of Nordic’s tools; is there a way to switch to JLink?
I primarily want to use this board as a BLE sniffer with Wireshark to troubleshoot a different project, which for a noob like me, seemed to be easiest by following Nordic’s guides and using their software to interface. So please let me know if there is an easier way to achieve that goal with Makerdairy’s hardware.
Thanks

Edit: I was able to find instructions for flashing the bootloader. I’m able to put the board into bootloader mode (comes up as “CRP DISABLD”), but the storage is only 64kb instead of the 108kb needed for the nRF52 J-Link firmware on Nordic Semiconductor’s website. I’m not sure why the Makerdairy board would have less storage for the bootloader, so I’m guessing this is a problem on my end. Let me know if you have any ideas.
Thanks again
