Hi I am trying to program a bootloder and I keep getting this message,Expected signature for ATmega328P is 1E 95. I am using a Uno to program and the ender 3 main board.
Please help!
Please do this:
- (In the Arduino IDE) File > Preferences
- Check the checkbox next to "Show verbose output during: upload
- Click "OK"
- Tools > Burn Bootloader
- After the Burn Bootloader process fails, you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
- In a forum reply here, click on the reply field.
- Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
- Press "Ctrl + V". This will paste the Burn Bootloader output between the code tags.
- Move the cursor outside of the code tags before you add any additional text to your reply.

avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Is this what you wanted?

This is a symptom of the target chip's clock not running. That can happen when you are trying to switch a bare ATmega168/328P from a crystal oscillator (like on an Arduino) to the internal 8 MHz RC oscillator. An ATmega that is expecting a crystal needs that crystal to run its system clock. Without the clock you can't burn a bootloader.
There are two ways to provide a system clock:
1: If you can find a crystal between 8 and 20 MHz you can connect it between pins 9 and 10 of the target chip. Do that and try again.
2: If you can't find a spare crystal or you try the crystal and still get the "Device signature = 0x000000" error you should get this modified ArduinoISP sketch from adafruit: GitHub - adafruit/ArduinoISP: A fork of the ArduinoISP that has 8mhz output clock Go back to Step 1 and upload this version of ArduinoISP to your ISP Arduino. Connect Pin 9 of the ISP Arduino to pin 9 of the ATmega168/328P on the breadboard. That will provide an 8 MHz clock to allow programming without a crystal.
If you try both methods and it still fails with "Device signature = 0x000000" you might have a chip with configuration fuses set to disable serial programming. To fix the fuses you will need something like the HV Rescue Shield 2 from MightyOhm (HV Rescue Shield 2 | MightyOhm). That uses High Voltage Serial Programming to reset your ATmega/ATtiny configuration fuses to factory defaults. If that doesn't work your ATmega/ATtiny is probably damaged beyond use.
