 Bigger Bigger  Smaller Smaller  Reset Reset

I'm trying to get my first Mini Pro Atmega328 5v 16M module to operate, but I seem to be having a loading failure.
The power LED is on, and the Pin 13 LED is blinking, with the Blink sketch pre-installed I assume.
I'm receiving the "avrdude: stk500_getsync(): not in sync: resp=0x00" error and no load.  

I have verified my serial port's operation via loop test, and tried other mini pro models under Board select.  
I'm trying 9600 baud, same as used with a working Nano Atmega328 5v 16M module I have?

I have also tried connecting the Serial DTR to the Mini's GRN pin as found here: http://tutorial.cytron.com.my/2012/02/28/loading-program-to-arduino-promini/, but it didn't help.

Any suggestions appreciated.

The last thing you did is where you should start looking.

The way you have it in your schematic isn't the same as how you have it wired up!

I have solved this.

I had not found that post, but learned about the Reset switch use.

I found that the Reset button must be pressed before pressing the Upload, then release as the IDE begins displaying Uploading.
I also powered the Mini Pro from the serial adapter 5V power, that may or may not have helped.
Thanks
