Unable to set up nRF52840-DK

[Raghav_Janamanchi]

Hi I purchased nRF52840-DK board recently. I'm able to connect it to Mac OS Mojave and I see that the LED5 is blinking every second. However none of the LED1-4 are blinking and I'm not sure what to do here. I followed the steps listed out here - https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52-DK/Getting-Started

and I downloaded the latest firmware and drag-dropped the hex file into the JLINK drive that I see in the file explorer but it didn't work.

Can you please help me?

Thanks, Raghav

Can you try downloading and installing the J-Link Software and Documentation pack? Try with the latest version first. If that doesn't help, try version 6.22g, as there was an issue with newer versions earlier for macOS which I'm not sure if is fixed.

Best regards,

Simon

I kind of ran into the same problem and after doing all of the above and wrting the soft blink hex on the device, the LED still doesnt glow. Any suggestion what to try next.

Hi

This case is more than a year old, and a lot has changed since then. If none of the suggestions below help you, I suggest you create a ticket of your own, where you can link to this case to refer to what you've already tried.

Best regards,
