I bought an Arduino Mini and also an Arduino USB 2 Serial Converter. While trying to program the Arduino Mini, I get this error:

avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x00

After doing some research I tried many things like changing the settings, serial port, made sure I'm using the right Arduino etcetera.

Some points to consider:

  • I tried burning the bootloader using my Arduino Uno.
  • Uploading sketches to the Arduino Mini using my Arduino Uno works (so problem is not directly with the Mini).
  • I am pressing the Reset button before uploading. I also tried hooking a capacitor and the Reset wire directly. No change.

The wiring (I also tried connecting TX of Mini to RX of serial converter, and vice versa):

The Arduino USB 2 Serial converter was defect (even though brand new). I bought a cheaper (7 Euro) FTDI to USB and I can now upload.
