I have made a l80 GPS shield for Arduino. Have Designed the schematic for same but while assignining Footprint to all the components, footprint of l80 is not getting assigned, while rest of the footprints are assigned in the same way.
not enough information to help.. can you be more specific what it is you're doing (step by step) and what doesn't work?
Some components may have associated footprints. If the component you are using does not then you must assign a footprint. As Joan_Sparky says, we need a little more info to help out.
