JTAG vs SWD with MCUXpresso and Kinetis K22.
I have a new PCB with a K22FN512VDC12. I can connect to the part with a PE Micro Multilink Universal using SWD mode. All is fine.
One of the SW developers claims he could Debug in JTAG mode on another K22 board, but if I uncheck the SWD select box in the config for the Multilink with this board it fails to connect to the target. I am running the latest MCUXpresso version and just loaded the latest driver from PE Micro. Physical interface is just straight short wires between the CPU and the JTAG conn.
I am honestly not concerned but before I go too far down this hole I want to understand if this SHOULD work or not. Is there something special config wise to enable JTAG mode operation?
