Burn Bootloader ATmega8A AU

Other Hardware 3rd Party Boards
1

Hey guys i really need your help, I have a arduino uno and i want to burn the bootloader of the microcontroller ATmel ATmega8A AU.

here where i bought it: https://www.dzduino.com/avr-microcontroller-atmega-8a-au-smd?search=atmega%208&description=true

Here is the data sheet: http://ww1.microchip.com/downloads/en/DeviceDoc/ATmega8A-Data-Sheet-DS40001974B.pdf

Please help me, i can make a pcb by myself

What exactly do you need help with?

"How to burn the bootloader of Atmega8A AU using arduino uno ??",

the schematic i guess i must use two capacitor of 22pF and one 16MHZ oscillator ?

4

Here's a schematic:

MiniCore also provides a boards platform for any common configuration of the ATmega8A. You'll find installation instructions as well as instructions for burning the bootloader at the link above.

Not only oscillator. Minimal circuit must have power, oscillator, reset and of course ISP (24.9 - Serial programming - datasheet). Bootloading is pretty similar as for 328P. Look for tutorials here on web, how to bootload with Arduino as ISP there are also schematics. However, SMD version is a bit problem. PCB is kind of definitive and not very feasible if you have no tested circuit and appropriate knowledge. It is good to have a socket for this package type. Without this I used to connect wire to a pin with heat shrinking hose.

I tried to make a small pcb with the right schematic as shown i soldered all the part and add a female header, and i still have a problem, I'm having error when i want to burn bootloader.
I used the arduino uno as asp then i changed the board for atmega 8.
The error message is invalid signature.
I checked again and again my wiring and my pcb circuit... No results
I'm making another pcb with only a female header related to vcc, gnd mosi, miso, sck (15,16,17,29,gnd and vcc) and reset.
I'll try with my Breadboard plug the crystal and the two capacitor and the resistor.
I hope it will work cause i tried so many time and always problem of " invalid signature "

The error message is invalid signature.

Please do this:

  • When you encounter an error, you'll see a button on the right side of the orange bar "Copy error messages" in the Arduino IDE (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). 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 error between the code tags.
  • Move the cursor outside of the code tags before you add any additional text to your reply.

If the text exceeds the forum's 9000 character limit, save it to a .txt file and post it as an attachment. If you click the "Reply" button here, you will see an "Attachments and other settings" link that will allow you to make the attachment.

avrdude done.  Thank you.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

this is the error while burning the bootloader

Anyone have a solution for me, please
