ATMEGA 328P not responding to USBasp

[bharatcs]

I tried to program an ATMEGA 328P using an USBasp with arduino IDE .But I forgot to burn the boot loader instead I uploaded the  led blink sketch.
Now the ATMEGA 328P does not respond.Is it due to incorrect fuses?
I even tried low speed programming 
Error message :
avrdude:error:programm enable : target doesn't answer.1
avrdude:initialisation failed,rc=-1

It could possibly be an incorrect fuse for the clock. I've encountered this before when burning stuff on Atmegas. What you want to do is hook up an external clock signal to the controller then try to reprogram the fuses.

For the external clock signal I used another microcontroller and just toggled the pins on and off in the main loop.  It may not work for you but it worked for me every Atmega I've had issues with so I can reprogram the fuses.

By the nomenclature, sounds like you are using the Arduino IDE.

I assume you attempted to burn the (standard) bootloader, in doing so the first thing that does is set the fuses to expect a (16MHz) crystal/oscillator on it's pins, and you will need to provide that, or inject a square wave into XTAL1 in order to program again or change the fuses.  Note that the bootloader won't have actually been burnt in, only the fuses will be changed at which point the bootloader could not be uploaded due to no clock.

Thanks Guys.I will try to hook up an external clock.

It Worked.
