Programmer is not responding

Dear all,

It seems that I have the same issue...

Binary sketch size: 1108 bytes (of a 14336 byte maximum)
tools/avr/bin/uisp -v=4 -dpart=atmega168 -dprog=stk500 -dserial=/dev/tty.usbserial-A50018lJ -dspeed=19200 --upload if=/Users/kotobuki/Desktop/arduino-0008/examples/Digital/Blink/applet/Blink.hex

Transmit: { 0 [30] [20] }
Programmer is not responding.

  1. press the reset button
  2. press the "Upload to I/O Board" button
  3. the Rx LED blinks once
  4. error message...

My environment is:

  • MacBook (Core 2 Duo 2.16GHz, 2GB RAM, 160GB HD, OS X 10.4.10)
  • Arduino NG rev.C (S/N 9311)
  • Arduino 0008 Alpha

I have no problem communicating with another USB device that also use FT232RL. I also tried different timing (e.g. press the upload button before pressing the reset button etc.) but got no luck. I'll be able to try with another Arduino NG around next Monday, but it would be much appreciated if you give me any suggestions about this issue.

PS
The Arduino Troubleshooting guide says:

Make sure there's a bootloader burned on the Atmega8 on your Arduino board. To check, connect an LED to pin 13 and reset the board. The LED should blink.

Yes, it blinks. But according to several posts in this forum, it should blink 3 times, but mine blinks forever at several Hz. Is this correct?
