I am trying to burn bootloader in atmega328 from this tutorial "https://docs.arduino.cc/built-in-examples/arduino-isp/ArduinoToBreadboard". but it not burning. I am getting this below error. what is the problem I cannot understand. please help.
What is the exact type of 328 chip that you are trying to program ?
There are 2 "flavors" of 328 chip in the DIP package. The 328P-PU and the 328-PU. The 328P is the "Pico Power" lower power chip and the non-P is not. That looks to be the non-P chip.
I use the MiniCore core and Arduino as ISP to program the non-P chips. It works great. Still uses the Optiboot bootloader.
After you install the MiniCore core using the IDE boards manager here is how to choose the 328 (non-P) chip.
Not working for me. I got the same error.
As far as I can tell that is a non-P chip. They have been the only ones available lately.
What programmer are you using? Please post a diagram of your wiring. Post photos of your wiring.
What were the other settings in the MiniCore menu (clock source, frequency)?
Where did you get your instructions for bootloading? Post a link, please.
I have already mention the reference link in the question.
How about my other questions, requests?
The setup in the illustration for wiring to bootload the 328 is missing 0.1uF ceramic caps, one from Vcc to ground and one from AVcc to ground on the 328 to be programmed. Those caps are very important.
There also should be a 10uF cap from reset to ground of the programmer Uno to disable the autoreset of the programmer.
In Preferences, turn on Show verbose output during: [X]upload. Then the messages will tell you what signature values you read. If you got 1E 95 14 then the problem is you told the IDE you were uploading to a 328P when you have a 328. if you are getting a signature of 00 00 00 or FF FF FF you probably have a wiring error.
