Default Discussion: Atmega fusebit doctor (HVPP)

Quote:
Atmega fusebit doctor, as name says it, device for repairing dead Atmega family AVRs by writing wrong fusebits. Most common mistakes or problems are a wrong clock source (CKSEL fusebits), disabled SPI programming (SPIEN fuse) or disabled reset pin (RSTDISBL fuse).

Firmware version 2.07 and PCB with added pulldown resistor for +5V line
"After adding a 100ohm resistor, circuit is more stable, this fixes a problem when some of chips worked in non-HV mode and we can’t fix the RSTDISBL fusebit."

I have a question regarding DOC chip programming.
Should I set fuses for DOC chip or just program the Flash memory ?

Unhappy

I have great problems with the functionality of a doctor. Programmed I eep file from version 2.03 and update hex file from 11th Fuses I also set the project as the author writes, but sometimes when you press the button flashes green and then the red LED lights up again. Inserting any circuit heal me after pressing the red LED goes out and nothing more is done. after approximately 1 minute the doctor does not cure anything but warm. Please help. already I'm really unhappy. Thank you for your willingness and advice.

Any help appreciated
