Take a look at this MCPU in my schematic:
Please see pins 7, 12 which are not connected. Also look at pin 9, which is assigned to UART2_TX and pin 14 assigned to SPI1_MOSI.
When I import my changes to the PCB from the schematic I see my changes:
However, the PCB will not reflect the changes.
Not sure what to do with this. I've restarted the application and opened/closed documents. But at this point I can't proceed with the design.
