Hi all, I have a from-the-factory 328P on a breadboard. (I also have a couple seemingly unresponsive 328Ps with the Uno bootloader.) I also have an Arduino Micro (with the 32U4) with ArduinoISP loaded to it.
It's not working.
avrdude: Device signature = 0xffffff [or 0x000000, sometimes] avrdude: Yikes! Invalid device signature. avrdude: Expected signature for ATMEGA328P is 1E 95 0F
avrdude: safemode: lfuse reads as FF avrdude: safemode: hfuse reads as FF avrdude: safemode: efuse reads as 7 avrdude: safemode: lfuse reads as FF avrdude: safemode: hfuse reads as FF avrdude: safemode: efuse reads as 7 avrdude: safemode: Fuses OK
regardless of whether the 328P is connected to the SS, MI, MOSI, SK pins on the Micro board or the 10, 11, 12, 13 pins on the Micro board or nothing at all. So I'm thinking the ArduinoISP code is not set up to use the 32U4 correctly. Or else I'm using avrdude wrong, but I get the same error when I try burn the bootloader from within the Arduino IDE, so I don't think it's that.
What should I do? Thanks!
