Arduino Ethernet

Development Tools IDE 1.x
1

I am new to Arduino, purchased an Arduino Ethernet board, not a ethernet shield. I purchased a USB-to-Serial Bridge - µUSB-PA5 from sparkfun.com not realizing that this was actually intended for the arduino.

However I found the pin out for both the Arduino board and the USB to serial bridge and wired it up like this.

Arduino Board USB to serial bridge

1 Reset 1 Reset
2 TX 3 RX
3 RX 4 TX
4 +5 5 +5
5 NC
6 GND 2 GND

I installed the drivers, FTDI version 2.8.30

When I connect the everything up to the computer the COM port shows up.

Then I start the arduino programming environment, load the blink program. From the tools menu I made sure the Arduino Ethernet is select for the board, and COM 4 for the COM port.

I hit the upload button, shortly after this message appears:

Binary sketch size: 1,084 bytes (of a 32,256 byte maximum)

The LED on the USB to serial bridge board blinks 3 times.

Shortly after that this message appears:

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

Did you press and release the reset button on the Arduino when the IDE code upload started?

Of course shortly after posting this I did exactly what you suggested. I had to disconnect the rest connect and then hit the rest button before a uploaded the program, and released it shortly after uploading

try to add a 100n cap between the 2 reset connectors,
