searched and tested anything I found on the internet about my problem:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

went through the troubleshooting#upload too!

Bit it still persists

OS:Windows 7 64bit
board: arduino pro mini 5v (16Mhz) 328  (selected in the arduino software)
cable: FTDI

when I plug the arduino in the device manager appears COM4 so I select this also in the arduino software (I guess this means I'm not having driver problems, right? cause I did in the begining)

Intersting is that when I plug the arduino in the PC I see a green and a red led blick once. In the troubleshooting it says the green should be on all the time.

removed windows firewall and all the programs in the back - teamviewer, deamon tools, skype etc.

in the USB settings in the device manager I changed the Port Settings to 115200 Bits per second they were 9600 as default. 115200 bps is know to be an arduino environment. Is this true?

I've attached a pic how I've connected the arduino to the cable. Hope I have connected it correctly, haven't I?

Thanks you


Your ftdi lead is on backwards - also when you upload - tap reset when the sketch size shows on the screen, this may help.
