Problem to connect Segger J-Link to nRF52810 (WARNING: RESET (pin 15) high)

[r3tr0]

Hello There,

i have made an Selfmade PCBA with an nRF52810 and it is my first time that i am working with those Chips.

I have used the reference Design for this board and now i am trying to connect my Segger J-Link to the nRF52810.

Everytime i try to connect to my Target with the J-Link Commander i get an error called:

WARNING: RESET (pin 15) high, but should be low. Please check target hardware. 

My J-Link Commander is configured as:

SWD, 4000 kHz interface Speed and NRF52810_XXAA as device. 

I don´t know what i am doing wrong, i think i have soldered everything fine, have my 32MHz Crystal, have the J-Link 6Pin Needle Adapter to connect it.

Have my external 3.3V for the Chip.

But even when the J-Link Commander tells me this error, why pin 15? In my Opinion the Reset Pin is on Pin 24 and not Pin 15.. 

I hope somebody of you can help me!

Hi

I agree that this seems strange. Have you tried using an oscilloscope, logic analyzer, or similar to check the state of the actual reset pin, P0.21 to see if it is high or not when your app is running? If that's the case, you can try adding a pulldown resistor to the reset pin to avoid it from staying high.

Best regards,

Simon
