I am using usbasp with atmega16a. I try to use external crystal 16MHZ with 22p capacitor. With mistake i use this command to change the fuse setting. 

avrdude -c usbasp -p atmega16 -U lfuse:w:0b00000000:m hfuse:w:0b10011001:m

The atmega16a is dead. How to fix it?

pls. Any solution:

  • \$\begingroup\$ @RedGrittyBrick What does it mean check XTAL2 pin with a 'scope to see if the clock was running'? But then i try to run with atmega8l still not working internal crystal. How i reset usbasp to factory setting? \$\endgroup\$

  • \$\begingroup\$ @AlexCerry There is no "internal crystal" in Atmega, only simple RC oscillator. \$\endgroup\$
