Is reset pin required for J-Link connection of chip?

[pkr2258]

hello,

While studying SW with nRF52-DK...

Now I am drawing up a circuit diagram to make a PCB.

look at the nRF52-DK schematic

It seems that only two pins, SWDIO and SWDCLK are used, do I not need to connect Reset?

We plan to use it as J-Link using P20 of the nRF52-DK board.
VDD / SWDIO / SWDCLK  / GND

Can I just connect 4 pins?

Yes, you can only use VDD / SWDIO / SWCLK / GND, the firmware will be downloaded without any problems.
