I’m attempting to program my board using the nRF Connect SDK, with the nRF52840 development kit as a more affordable J-link. I’ve wired it up like so (Image borrowed from this post):
After connecting everything up, it looks like it should be working; I see in the terminal that the flash is programmed and verified, and it becomes unrecognized by Arduino afterwards so something happens, but it doesn’t appear to do what it should, even a basic blinking example. Have I connected everything correctly? I connected VDDnRF to 3v3 on the expansion board.
I am unsure what to make of this. The development kit I am using for its J-Link is running the Blinky example, and I’m assuming what I’m seeing is the kit rather than the board attached to it.
