RP2040 exposes its DP via a low-pin-count Serial Wire Debug (SWD) port: by talking the SWD protocol over this port, a host computer can control each core’s AP, in order to debug a program ...

The microcontroller itself provides a debug port (DP) that connects externally to pins on the package and internally to any AP in the system. For example, the RP2040 provides its DP through a Serial ...

The ARM SWD technology, introduced in 2004, is widely deployed in silicon and supported by a large number of tools vendors. SWD replaces the alternative 5-pin JTAG debug port providing all the normal ...

JTAG and SWD don’t have set voltages, so in the wild you could run into logic levels from 1.2 V all the way to 5.5 V. While being able to use a bare Pico as a debugger is a neat trick, adding in ...
