ATMega328-pu not responding on stand-alone PCB?
My ATMega328 based circuit is similar to the stand-alone Arduino design shown here. However even when I run a simple blink program the LED at pin 13 does not blink and I get no response from the microcontroller. I have tried the same circuit on a breadboard and it worked well. However when I transferred this on to the PCB there is no output.
I've checked the continuity and all the coppertraces seem to be fine. I program the chip using my Arduino Uno board and place it in the circuit. This works on the breadboard but not on the PCB.
I have attached the pictures of the PCB and a schematic diagram for reference. I'm completely stumped as to what the problem might be and would greatly appreciate any help.
