hi
im trying to burn a bootloader using a usbtinyisp on the above chip, but it get the following error message
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.
can someone please tell me how to override the error?
i can burn bootloader on a 328p-pu chip ok well it says burning done and upload sketches to it, so im assuming its ok
just wondering whats the difference between the ic's?
thank you
'328 and '328P have different Signature bytes.
You need to address that.
hi can you tell me how to do that please
Hi,
I've programmed 328-Pu flawlessy with this method http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html
At first I have a similar error message so I have to add the configuration for 328-pu new chip. Basically what I've done is I've text edited avrdude.conf and I've just copy&paste 328p-pu config changing id= "m328p" to "m328", desc = "ATMEGA328P" to "ATMEGA328" and signature = 0x1e 0x95 0x0F;" with this one "signature = 0x1e 0x95 0x14" (328_pu chip signature). So I guess there's must be a similar config file in usbtinyisp to add the new chip signature.
I hope it can help and sorry for my english.
Regards,
Juan
hay thanks juan,
do you have to change it back afterwords?
Hi jonisonvespa,
No, 've just add the modded 328p to 328 data, after 328p data in avrdude.conf. I can choose the 328 chip in device menu now keeping 328p option too. Its very easy and simply if You owe a duemilanove board. I can send You my modded config file if you want.

Juan
