Hello,
Im trying to debug a custom pcb with an nrf51822 SoC, however i can't seem to connect it.
Im using a genuine jlink Plus debugger and tag-connect 6 pin adapter to the pcb board.
When I run Jlink commander, it reads the VTref = 2.996V. For options i pick the right device, SWD as target interface,
the speed at 1000 kHz (i've tried many different settings, doesnt seem to be the problem).
I also tried power cycling the device, and resetting it, and every combination of settings and power states,
but i always get "Cannot connect to device" after about half a second delay.
The output of the jlink log file:
