Fusebit setting for ATmega8L

pylon:
HighFuse to F9 disables ICSP programming. If you don't have a high voltage programmer, get a new chip.

Thanks for your reply, I find this post, and wire the beard board version.
Now my ATmega8L was come back.

Some comment for anyone who hit my issue.

  • There are 2 version of AVR HV RESCUE SHIELD on provided website, both of them are ok. I follow the simple one (v1)
  • Reset the Fuse to default; LFuse: 0xE1, HFuse: 0xD9;
  • Update config (LFuse and HFuse, F_CPU, etc) in arduino boards.txt
  • After reset Fuse successfully, using ArduinoISP to upload the BootLoader
  • Upload you sketch to ATmega8L via ArduinoISP

PS: pylon, just add Karma to you.
PS2: hopefully if I have time, I may try to design the Arduino Nano / Pro Mini version which replace the AVR HV RESCUE SHIELD.
