I came to Eagle having attempted Kicad and found a far greater ease of use with Eagle. I have alread made a successful two sided board.
Now I'm having a problem that I can't solve:
I have carefully edited my schematic and am left with just a few trivial warnings in ERC. Specifially I have a 12 pin connector to the outside world and all schematic connections to it are correct and consistent in "name" all along their lengths (I warrant there are no mis-connects). ERC tells me "Board and schematic are consistent". Now, I go to the board layout and on my 12 pin connector five air-wires are missing: a ground, a 12V power line and three lines that go directly to I/O ports on my microcontroller.
I checked the pins on the connector and all are labelled "passive".
Please tell me what obvious mistake I'm making?
