If the project uses the expansion pins on the development board, such as the I/O in the Arduino or Raspberry Pi interface, then you need to constrain the corresponding pins in the project. One is to enter the corresponding PIN number in Location. If you use the schematic diagram, you need to search twice to get the PIN number. For example, if you use the 3rd pin of the RP1 Raspberry Pi interface, its network number is RP_IO02.

Search for RP_IOI02 and find that it is connected to T1_N via a resistor.

Then search for T_N to confirm that it is A7.

Finally, enter A7 in the pin constraint to complete the constraint of a pin.

If you use a lot of pins, it will be very troublesome. It will take a long time to search like this every time. I found a document that can solve this problem.

It is so convenient to use this document. Who is so talented? The creation date of the file seems to be one minute ago.

If it is the pin used in its demo, it is more convenient to copy it from the project.

These pins don't seem to be used in the example program. Bigbat's post mentioned the user manual of this development board. At first I thought the manufacturer didn't have this manual.

It turns out that this development board has a user manual, which contains the corresponding definitions.
