Boot Cloner

Hi,

I've tried to make a boot cloner like this one ...

http://www.arduino.cc/playground/BootCloner/BootCloner

... but it doesn't work well and I don't know why. It starts with the green led (idle) ... I push the start button ... and it turns inmediately to red (problem). It only stays yellow (working) while I'm pressing the start button.

I've tested all the conections in the prototyping board and the are no short-circuit. The conections are like in the schematic.

Can anybody help me?

Here are you are some photos:



Thank you very much,

Igor
