Hello,
I'm quite new to Arduino, I have one Freeduino(16Mhz) and I use that to boot load other micro-controllers using ICSP pins.
I use ZF-007 ISP programmer to burn hex files of boot loader on micro-controllers. I've tried burning ALL boot loaders(given by Arduino for 168 controllers) on my new ATmega168A-PU, it writes flash memory successfully, but when I remove the ISP and attach USB cable on Freeduino, it is not loading.
I have read ATmega168A PU data sheet and for 4.5 to 5.5 voltages it supports clock with maximum frequency 20Mhz
I am not able to locate the problem which is frustrating.
Any help will be appreciated...

The processor does but not the boot loader unless you get a special 20MHz one.

Is there an error message?

Which board are you selecting in the Arduino IDE?
