LED stops flashing after removing programmer

(1/6) > >>

Simon:
I am venturing into the AVR world, after much effort I got a led to flash, so long as the AVRISP2 remains connected (just powered, does not need any PC program running)

What the blinking hell happened ?

dr_p:
I don't know AVRs but look into the reset pin and how it works. My PIC used to do that.

Simon:
The reset is pulled high with a 10K resistor

dr_p:
You do have external power, right? :D

Simon:
yes,

Could it be fuse settings ? maybe the programmer is providing the clock or something ? or I'm in some sort of debug mode ?
