Hi
I have built a board using the NRF52840 chip.
When trying to connect to it, I get the message "Target Voltage Too Low".
The NRF chip has a default reference voltage of 1.8V before it's set otherwise in the software.
I have measured the voltage from the chip all the way to the input pin of the Jlink.
So it should be able to read it.
Is there a lower limit for the reference voltage? Is 1.8V too low?
Or is there anything else I need to check?
All help appreciated.
