I am using an Arduino UNO board and trying to interface IMU sensor (GY-521) and GPS sensor (Ublox Neo-6M) at the same time. The connections of the IMU and GPS are as follows
IMU to Arduino :
Vcc --> 5V,
Gnd --> Gnd,
SDA --> A4,
SCL --> A5,
INT --> D2
GPS to Arduino :
Vcc --> 5V
,Gnd --> Gnd
,Tx --> Rx
,Rx --> Tx
Now when I used the IMU sensor alone and tested it with the Jeff Rowberg library, it was working fine. But as soon as I make the connections with the GPS and upload a program, the IDE gives the following error:
Arduino: 1.7.10 (Windows 7), Board: "Arduino Uno"

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
I can't seem to spot the problem. Kindly help me out as I am new to the arduino development. Thanks.
