Hi i am having a problem with my atmega 32. I used 16 mhz oscillator and a program using usbasp and extreme burner in my mega32. first i burnt the program and then i wrote LOW Fuse = 0xFF and HIGH Fuse = 0xC9. after that i tried to read the fuse bits and it said that programmer can't connect to the target chip. this problem occured with 4 of my mcu chips :( can this problem solvable? :(

Please help

There is a difference between an oscillator and a crystal. You said oscillator. Did you mean crystal?

You fuse values seems to be correct for a crystal (according to http://www.engbedded.com/fusecalc).

Tell us how you wired up the crystal (schematic? what load capacitors? physically mounted on a breadboard, perhaps?)

There's your problem.

EDIT: Read data sheet. Page 26-27, for a starter on this specific problem.
