Thank you. i then try again using the -F parameter but i get this result [filyx20@DellBeast build]$ sudo avrdude -c usbasp -p t2313 -F -U flash:w:us_eastern.hex:i avrdude: error: program enable: target doesn't answer. 1 avrdude: initialization failed, rc=-1 avrdude: AVR device initialized and ready to accept instructions avrdude: Device signature = 0x6b72be avrdude: Expected signature for ATtiny2313 is 1E 91 0A avrdude: NOTE: "flash" memory has been specified, an erase cycle will be performed To disable this feature, specify the -D option. avrdude done. Thank you. i try to check if the chip still works but without any sucess, and tryig to see if the utc switch works (the reason why im updatting) it dosent. thanks for any help. -------------

yeah whatever Admin Posts: 538 Joined: 4-May 16	Hi, it's probably that something wasn't wired up correctly. I would recommend to never use -F, if it can't talk to the chip then forcing it to send commands won't work either. Are you sure the chip is powered? The USBASP programmer has a little header pin where you can set the voltage, should be set to 5V. -------------
