Hi Lefty,It's an ATMega328 on a small breakout board with the FTDI 6 pin header together with the reset capacitor.It's weird because it upload once but not the 2nd and so on.
So, the issues comes down to the waiting stage in bootloader?
I'm using a simple FT232 breakout. I double check the wiring, point-point everything seems to be connected properly.I also tried using Sparkfun - http://www.sparkfun.com/products/9873Both came out with the same result.But, I manage to get it to upload once everytime after bootloader burning process. I repeated this couple of times and it's constantly the same pattern.
Lefty,I attach the schematic. I think it's pretty standard. XD
