Firstly: I made a change in the schematic and inserted another component. Now I wanted to apply the changes to the board by hitting the corresponding button (as usual). But for some reason I don’t understand, Kicad wants to insert all the components of the circuit diagram into the board again. That is, the previously inserted and placed ones a second time, so that they would be there twice.
Secondly: I had a programme crash once and since then, when I open the schematic editor, I get the message that it is already open and whether I want to open it a second time. If I confirm this, it opens and I can work normally.
I am working with Kicad 7.07 does anyone have any ideas? Thanks in advance.
The crash leading to “already open” message is probably related to a “.lck” (lock) file that gets generated by KiCad in the project folder for each open design file. The lock file is named something like “mydesign.kicad_sch.lck”. You can safely delete the “.lck” file if it is erroneously sticking around after crash.
If I update the PCB, the PCB editor throws all the components onto the worksheet again.
This is a sign that schematic and pcb were not in sync prior to the “update pcb from schematic” command. (why this happened is another question - there are many reasons).
The fact that cross-highlighting works is not a clear sign that the synchronization is still correct, I also had situations were cross-highlighting works, but the “update pcb” command puts new footprints onto the board.
