Another avrdude: stk500_getsync(): not in sync: resp=0x00

spcomputing:
If you are labeled correct, you are going Rx->Rx/Tx->Tx and it is not the "BAITE" board, you will need to cross the connections Rx->Tx and Tx->Rx. When you upload, you will need to hold the reset and wait till the Tx on the USB2TTL board Tx LED Flashes 2x. You might want to test with the UNO Optiboot and the Duemilanove 328 boards in the Arduino IDE.

Later, you might want to hook up a 0.1uF cap to Atmega pin1 and your USB2TTL RST (DTR?).

I don't understand what does it mean "you are going Rx->Rx/Tx->Tx and it is not the "BAITE" board, you will need to cross the connections Rx->Tx and Tx->Rx." Could you explain?? And what is the BAITE board?

Do you mean the driver of COM port? It says the device is working properly.

Also, I bought the board from DX.com, and it's not an original. However, its printed in the board "Arduino Duemilanove" and in the chip ATMEGA328P-PU.
