The serial port is MUCH easier than JTAG (if you can FIND the JTAG port).
There are some K3 links in the simple debricking sticky.
The JTAG port on the K3 is a labeled collection of contact pads.
The harder part is identifing which signal is on which pad.
Then you only have to identify which bit of which register does what inside of the SoC.
Maybe better that you stick to the goal of using the serial console connection.
Although your sharing any JTAG information you have on the K3 would be nice.
