Arduino zero SWD pinout

Other Hardware 3rd Party Boards

Hello i didn't want to mix my programming Question with my hardware micro controller question. But A guy i use to know made a Zero board for me using the Samd21 chip and the zero bootloader. He made a programmer for me using a read Gen arduino zero board through the SWD pins. From what I'm seeing there are only 4 wires being used out of the whole 10 pins on the SWD pinout. SWO, CLK SWIO and ground. Is this correct?

I would like to see a photo and the pinout of your mysterious board

this is the official ARM pinout

and this is Arduino Zero schematics

I'm trying to draw something up on it. It has 6 pins but only 4 are being used. and so far i did trace out it looks like the CLK DIO REset and ground pins are being used.

Hello Juraj That is it. That is how the pinout is. Also i2c and 2 digital and 1 analog pin is broken out. I didn't need many pins for what i need to do.
