core13: An Arduino core for the Attiny13 *testers wanted*

Hi,
I just wanted to test your core13 sources on my platform here.
I run Ubuntu 12.10 with Arduino 1.0.1 and installed your version 16 (core13_016.zip).
As a programmer I use USBtiny and got that programmer into boards.txt.
It compiles well with no errors.

However, I get the following error from avrdude while uploading the blink sketch:

avrdude: Expected signature for ATtiny13 is 1E 90 07

  • Double check chip, or use -F to override this check.*

Do I have burn some fuses beforehand ?

When I run avrdude with 'avrdude -c usbtiny -p t2313' I get the following answer:

avrdude: Device signature = 0x1e910a
avrdude: safemode: Fuses OK

What does that 'device signature' mean and why is it different from the 'expected signature' ?

Thanks for your help.

Regards
