Yep after looking over the forum I came across how guys are flashing using the SWDIO and SWDCLK pins. I went ahead and hooked up all the JTAG pins anyways just to be safe.
I found this small solution for adding the JTAG pins for manufacturing programming & occasional debugging when needed. There is no part port cost when doing this but you do have to buy a connector that is already to go vs making your own Pogo Pin test jig.
It’s from www.tag-connect.com/
