Pin Function Inquiry
Thought for 33 sec
I couldn’t find any Flux documentation on explicitly assigning a net to individual schematic pins. It appears that connecting a pin to GND is done by wiring the pin to a GND symbol on the schematic.
You can explore more in the Flux Documentation or ask in the Flux Community for details:

@schematic Can you tell me the functionality of U1 pin 24?
Thought for 43 sec
U1 pin 24 (SWCLK) is the Serial Wire Debug clock input for the RP2040. According to the RP2040 datasheet:
Table
| Property | Detail |
|---|---|
| Name | SWCLK |
| Pin Number | 24 |
| Type | Digital In (FT) |
| Power Domain | IOVDD |
| Reset State | Pull-Up |
| Functionality | Provides the debug clock for the Serial Wire Debug (SWD) interface, giving external debuggers clock timing to communicate with both cores. |
