I resolved the issue by using a different micro USB cable. It seems like certain cables prevent the detection of the onboard debugger or the USB serial port on the NRF SoC.

Hi Priyanka,

It is currently in Default instead of nRF Only. I tried to enter the bootloader while it was set to nRF Only before this because I thought something happened to the Interface MCU.

The board I have is revision 3.0.0

I have also tried installing the mbed serial drivers, but the program says that no mbed microcontrollers were found.

Thank you

Hi,

Did you change the switch from nRF Only to Default while performing Step 4? Also, what is your DK revision?

Best Regards,

Priyanka
