Grove GPS and Yun board

Using Arduino Networking, Protocols, and Devices

I'm trying to use Grove GPS on board Yun with the sample i found on seeed wiki. (http://www.seeedstudio.com/wiki/Grove_-_GPS)

It works normally when I use UNO and the GPS output data is printed on serial monitor successfully.
However, when I use YUN as the board, there is no data printed on the serial monitor. There is no error also. I really don't understand what difference is between UNO and YUN. I just start to learn Arduino, and hope someone could help me figure it out.

I am having exactly the same problem. I thought there was a problem with the Grove GPS when I wasn't getting anything on the Yun Serial Monitor. Then I took the shield and plonked it on an UNO and it worked fine.

I have posted on the Seeed forum as well: http://www.seeedstudio.com/forum/viewtopic.php?f=17&t=6305
