Arduino UNO ATmega328p CH340G R3 + Yun Shield

Hi,

I'm trying to use Arduino R3 with Yun Shield (Geeetech) but I don't know if it's nessesary to disconnect de UART connection between ATmega328p and CH340G.

The references guide in this link (YUN SHIELD - Geeetech Wiki) talks about a procedure to imlement when it is used Arduino UNO, MEGA 2560 or Duemilanove, but my Arduino UNO doesn't have mega16u2 chip, but CH340G.

I have no problem to upload scketch with the Arduino IDE, but it fails when I run an example with the Console: "Connection closed by foreign host".

In some forums I have found that this problem is related to a conflict in UART. And thas my question.

Thanks.
