when I try to upload blink program to my Pro Mini, I get this error:

avrdude stk500_getsync() not in sync resp=0x00 

I've tried everything, changing the COM port, different USB cable and even another computer. Here is what I'm dealing with:

Arduino Pro Mini 328 5v 16M (Fake)

FT232RL USB to serial adapter

Nothing is connected to any pins on the Arduino, just trying to get LED to blink. I'm pretty sure the bootloader is installed, because when I hit the reset button, the LED blinks. I've tested the FTDI chip by connecting the TX and RX pins together, and it does echo in the serial monitor. Help appreciated!

  • Did you install the driver? What OS are you on? – Anonymous Penguin Jun 25 '14 at 0:45
  • Yes, the driver has been installed. I'm currently running Windows 7, although I have an IMac if needed. – Thesciman Jun 25 '14 at 0:55
  • Just curious, what happens when you use your iMac? I'm trying to figure out if it's your computer or Arduino. – Anonymous Penguin Jun 25 '14 at 1:24
  • I will try tomorrow and get back to you soon. – Thesciman Jun 25 '14 at 4:44
  • I've tried with my iMac and I get this error avrdude: stk500_recv(): programmer is not responding – Thesciman Jun 25 '14 at 15:33

You did set the Serial Port and then tell the Arduino IDE that it's talking to a Pro Mini right?

This gets me every time I switch between my Nano & Uno.

On the main menu [Tools]->[Board]=>"Arduino Pro or Pro Mini (5V, 16 MHz) w/ ATmega 328"

I've also had this problem trying to use a longer USB cable, it just wouldn't work. The stock cable (shorter) worked fine.
