Connection between symbol and footprint

[asteppke]

I followed the installation instructions, added a Pi Pico to an empty schematic and then used the Kicad function "Update PCB from Schematic". Currently this fails with the error message that the footprint under the designation "RPi_Pico:RPi_Pico_SMD_TH" cannot be found.

The footprint is located in a library called "MCU_RaspberryPi_and_Boards" instead, so editing the symbol to reference "MCU_RaspberryPi_and_Boards:RPi_Pico_SMD_TH" fixes the issue.

@asteppke you may be interested in #10. I think this simplifies installation significantly.

Use the steps on https://github.com/ncarandini/KiCad-RP-Pico/pull/10 but I get the same result.

The problem is: If you open the test project, the schematics and the board are displayed correctly: Even the 3dView:

But if you, by example, add a new <<MCU_RaspberryPi_and_Boards -> Pico Symbol>>, the correspondent FootPrint can not be found:

The error seems to be what the new "MCU_RaspberryPi_and_Boards.kicad_sym" file, reference the footprint for the symbol as "RPi_Pico:RPi_Pico_SMD_TH": and no the value which I think should be: "MCU_RaspberryPi_and_Boards:RPi_Pico_SMD_TH" just like the property for "Pico" on the SCH file of Test project.

If I start a new project and add a new MCU_RaspberryPi_and_Boards -> Pico Symbol, when try to create the PBC, the same error comes:

if I manually assign the Footprint for the new added symbol and then go to create a PBC all goes well.

By the way if you update the Test project PBC, seems the footprint get out of scale, the comparison with the footprint "Connector_PinSocket_1.00mm:PinSocket_1x20_P1.00mm_Vertical" is huge and the holes do not match: Seems the test schematics have the wrong footprint for the connectors, it uses 1.00mm pitch and the "RPi_Pico_SMD_TH" uses 2.54mm (0.10 inches) pitch

I am using KiCAD 6.0.10 in a new installation, Windows 11 fresh installed this morning.

I am missing some step? my KiCAD is messed up?

thanks for all your effort.

@impeeza did you ever figure this out? I'm having the same problem

[impeeza]

Still waiting for input.

Same problem here...

The files provided in this repo are configured as in the author's installation settings. After importing the symbol, the footprint and the 3D model, as in the install instructions, you must:

1. Open Symbol Editor:

2. Double-click on "Pico" symbol (1), and then on symbol properties (2):

3. In "Footprint" property, click on the value and then on the button to modify it:

4. Click "OK and Save. It should retain the config globally.

Thank you so much, @HugoCunha

Not sure, if this repo is still maintained - do you see any chance of this change making it upstream, @ncarandini?
