Signals and power lines involved in program/debug nRF52810

[Juan]

Hello,

We are currently developing a project based on nRF52810.

We are testing some examples to learn more about this chip.

Now we would need to know which signals and power lines are necesary to program/debug our own board.

We are doing a prototype board and need this information to make the schematic.

Perhaps, if you send us the schematic of the PCA10040 board, we could deduct all the signals involved.

Thanks in advance for your help.

Hi,

The nRF52810 uses the J-link SWD interface to debug and program the IC. In addition to SWDIO and SWDCLK you should route VCC, GND and the RESET signal to the J-link header. 

You can download the schematic of the PCA10040 on the product website here.

Also, see my answer on this thread for more information regarding SWD.

OK. Thanks
