I connected everything but the control tool shows all kind of mistakes, including some switches that I clearly connected.
You should solve all DRC errors before sending the design to a manufacturer in general.
- Via near track, this error should not happen if you enable DRC while routing new track.
- Track near pad, the same above.
- Two track ends too close, see assigned net of a track you have this error. Tracks assigned to different nets should not be connected each other.
You have some unconnected pins in your schematic. Run rule check on the Eeschema too.
Did you choose Epson TSX3225 for crystal X1? If so, please check its datasheet. Internal crystal of the TSX3225 is connected between pin 1 and 3, not between 1 and 2.
