I have brought an Arduino Pro Mini 5v 16 mhz and a USB FTDI adapter of Ebay.
To program it, I’ve hooked it up as follows:
DTR – DTR
TX0 – RX
RX1 – TX
VCC – VCC
GND – CTS
GND – GND
see attachment for picture
When connecting the FTDI to the Pro mini and then to the pc, I can see that the Pro Mini is running the standard blink sketch. When uploading my sketch, I choose COM7 (I know it’s the right port) and boardtype “Arduino Pro or Pro Mini (5v, 16mhz) w/ ATmega328”
When I press the upload button I get this error:
avrdude: stk500_getsync(): not in sync: resp=0x00
After pressing the upload button I can see the on board led (pin 13?) on the Pro mini is flashing a lot, and the TX led on the FTDI flashing two times, and then nothing more happens, the Pro mini goes back to running the blink sketch, and I am stock with the error message in Arduino IDE
I’ve tried adding in a 100 nf disc capacitor between FTDI’s DTR pin and the Pro mini’s RST but with the same result, getting the error message…
I have tried programming another Pro mini (100% identical) through the FTDI adapter but with the same result.
What am I missing? does anyone have a solution to fix this, which will enable me uploading sketches to the pro mini without getting the error message?
