I have project using a NANO (classic). The NANO stop working. I bought several NANOS both from Amazon and Aliexpress. Although the upload could not be done using the serial connection, with the programmer (USBTiny) there was no problem. However, with the new ones (all of them) I started to get the message:
avrdude: Device signature = 0x1e940b (probably m168p)
avrdude: Expected signature for ATmega328P is 1E 95 0F
Double check chip, or use -F to override this check.
avrdude done. Thank you.
I understand that to use this -F flag it is necessary to issue a console command that I do not know how to do it. Can someone help me?
