Narrative:

After pushback, #2 engine (right side) was started. Flight attendant at 2R door (right side forward of #2 engine) then reported a burning smell. Aircraft was parked and the first officer went back to investigate. Because of wind direction and description of smell, it was determined to be exhaust from #2 engine starting. The flight attendant at 2R reported the smell had dissipated and first officer reported no other odors. After takeoff at 300 ft, the 'avionics smoke' ECAM warning illuminated along with audio warning and electrical burning smell. These indications lasted less than 15 seconds. Aircraft was landed as soon as possible. Flight attendants reported no smell in the cabin during the event.
