RT600 - SWD interface

Hi All,

Had a question about SWD interface on RT600. Do we need specific RST signal for SWD interface to be asserted by the debugger tool?

 

As I know on other MCUs, we have used PON system/Reset controlled over GPIO/Reset over SW commands on SWD.    Please clarify if this holds good for RT600 or not.

Thanks!
Lakshmi

Hello Lakshmi, 

We would strongly recommend also including RESET in addition to SWDIO, CLK, and GND. For debugging, the tools may try to pull this in certain circumstances (depending upon debug probe, debug configuration settings, and tools).

Have a great day,

Victor
