My pixhawk hardware(pixhawk1) does not connect when rc.txt is in SD card.

I'm using the embedded coder support package for px4 autopilot.
When I do the calibration for pixhawk, pixhawk is connected with qgroundcontrol well and the led also worked well.
However, when I put rc.txt file into the SD card, pixhawk cannot connect with qgroundcontrol with error message : 'The vehicle is not responding' and the led light does not flash(off).
I think no flash led means that the pixhawk doesn't booted and I don't know why my pixhawk is not booted.
