Pro Mini - cannot upload second sketch?

Development Tools IDE 1.x

Hi

My Pro Mini was not marked on the board at all ito the voltage or the speed. The vendor where I bought the unit claimed it was 5v, 16MHz 328 unit.

I bought two, and after connecting to a FOCA board for uploading.

I forgot the FOCA output on 3.3V, and the first upload worked fine. Trying to upload another sketch however, keeps failing.

Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Pro or Pro Mini, ATmega328 (5V, 16 MHz)"

Sketch uses 1,030 bytes (3%) of program storage space. Maximum is 30,720 bytes.

Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

When I realized that I might have a different type of Mini, I started playing around with the options on both FOCA board ito VIO voltage, as well as in Ardui UI ito board types, ie, 5v 16MHz and 3V 8MHz.

I cannot get a subsequent sketch uploaded to the board - the sketch uploaded as a test - Blink - however still runs fine on the board regardless of whether I supply 3 or 5 v via FOCA...

looks like the problem is the auto-reset - and thankfully, it seems both my boards are indeed 5v 16Mhz, since after trying different combos of pressing reset button before and after pressing upload in UI, I do manage to get new sketch loaded. I still have a problem with knowing that the sketch was actually uploaded though. It's easy with the test sketch Blink, but my real sketch does not have visual cues wrt LED's, and I don't want to add it to my sketch since I want the leanest possible sketc ito power consumption...

Any ideas as to how I can resolve this?

[SOLVED] - needed to connect the DTR on FOCA to GREEN pin on Pro Mini....
