Dear people,
I am using also this core and have a problem with the device signature.
I built a very easy circuit with ATtiny13 as in all examples.
Using an Arduino UNO as ISP. Setup board and params correctly, UNO has the ISP already programmed in.
If I click burn bootloader, the following comes.

Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.

if I try to use the -F flag from command line, than it comes other message

What should I do, that I got a device ID ? or what should I do to overcome this verification error?
I appreciate any help
