  • Thank you very much for your answer. I tried to set fuse bits such that it can run at 8MHz internal clock. Before that, it was running at 16MHz external clock. It the fuse bits are set correctly, it thas the internal clock, otherwise, it would be running on external 16MHz clock. May be for the loose connection while writing the fuse bits, the USBasp programmer writes something different in fuse bits. What do you think? Commented Jul 3, 2018 at 13:19
  • @MuhammadMonirHossain Perfectly possible, yes. Or you may have calculated the fuse bits wrong - it's easy enough to do (I have done it myself before now). Commented Jul 3, 2018 at 13:20
  • I tried with AVR Dragon. But the signature is read 0xDFDFDF that is not expected. What might be the problem? Commented Jul 3, 2018 at 15:26
  • @MuhammadMonirHossain Are you wiring it up for parallel HV programming? Commented Jul 3, 2018 at 15:44
  • yes, parallel HV programming according to this Go to Device Connection Sheet from this link: microchip.com/webdoc/GUID-04E3421E-81C3-4E6C-BD29-9E1A7BAEBA7E/… Commented Jul 3, 2018 at 16:57
