[avr-chat] avrdude: error: programm enable: target doesn't answer.

[YuGiOhJCJ Mailing-List]

Hello,

I am encountering a problem with an attiny2313 micro-controller, avrdude-5.11.1 
and my USBasp programmer.
I am unable to send a program to my attiny2313:
---
$ sudo avrdude -p t2313 -c usbasp -U flash:w:main.hex

avrdude: warning: cannot set sck period. please check for usbasp firmware 
update.
avrdude: error: programm enable: target doesn't answer. 1 
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.


avrdude done.  Thank you.

I was able to do it just before I typed this:
$ sudo avrdude -p t2313 -c usbasp -U hfuse:w:0xdb:m -U lfuse:w:0xef:m

With all my other attiny2313 micro-controllers, there are no problems.
I am able to send a program to these micro-controllers:
---
$ sudo avrdude -p t2313 -c usbasp -U flash:w:main.hex

avrdude: warning: cannot set sck period. please check for usbasp firmware

Do you see why my attiny2313 micro-controller does not work anymore ?

Thank you.
Best regards.
