Arduino R3 w/o POE uploading problem

Development Tools IDE 1.x

Dear all,

I just got my new Arduino board (Arduino R3 w/o POE).
This one has no USB on it. I use FTDI 232 TTL cable to connect it.
However, I have the problem to upload the blink example to it.
It seems not the problem related to the cable and the FTDI driver because I can use the cable to transmit and receive data. What should I do next to figure out and solve the problem? The error messages for uploading are shown as below:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x29
avrdude: stk500_recv(): programmer is not responding

Thanks for any helps.

Could you have loaded a sketch that does a lot of serial output? When a sketch does a lot of Serial output it can be very hard to upload a new sketch. The uploading program on the PC sends a command to the bootloader and reads a response. The USB input buffer is full of whatever the sketch was sending and that data does not match the expected response. The uploader tries the command a few more times before giving up.

To upload over a sketch that floods the Serial output:

  1. Hold down the reset button on the Arduino.
  2. Unplug the USB cable. This causes the PC to flush the USB receive buffers.
  3. Re-connect the USB cable. (by continuing to hold the reset button we prevent new flooding)
  4. Begin the new sketch upload.
  5. WHEN THE RX LED ON THE ARDUINO BLINKS: release the reset button.

That RX blink is the first upload command being sent to the bootloader. Releasing the Reset button allows the bootloader to be ready for the first retry of that command.
