Re: Troubles with ATtiny85 fuses = 0xFF
Can you explain what you mean by "Then I am put it in socket and try to re-burn"?

I mean I am not remove the 328p form socket, then press the button to read the fuse again.
Re: Troubles with ATtiny85 fuses = 0xFF
You need to remove the 328P from the socket between fuse writing operations. Can you try removing it from the socket before you attempt to burn the fuses again?

I have to do it according to your step, but fuse always is 0xFF when first read. maybe these 328P are damage?
Re: Troubles with ATtiny85 fuses = 0xFF
That is strange. Do you have another 328p you can try?

I just have two 328P of DIP package now, when I get new 328P, I will try it again.
Re: Troubles with ATtiny85 fuses = 0xFF

Hi mightyohm,
I got new 328P, and it always have error, so I trace the PCB,
then find a trace not connect to 328P pin15, so it read/write has error.
This is my problem, because this PCB is make by me.
Thanks your help.
