Bootloader and upload to Atmega328P-AU

Quickly burn a bootloader to Atmega328 TQFP 32 pin chip using a USBASP programmer without needing to use an Arduino as ISP. This is an easy tutorial to use the Arduino IDE alone to program and upload your sketch on the fly while the SMD chip is still in your breadboard.

The parts list, schematic, and breadboard layout is available at:

I've never been so excited to see a flashing LED before, thank you.

[zwtsch]

thank you, sir. it's working perfectly.

Thank you for this video. I've searched for this information and viewed other videos and was still not sure what to do until I came across your video. Well explained and illustrated.
Cheers, Peter

You have saved my life, thank you so much for sharing your knowledge, YOU ARE AWESOME!

Thanks a lot for posting this. I am having a lot of trouble burning a bootloader. I have put breakout pads for SS, SCK, MOSI and MISO on my board, also have the 10k pull up resistor on the board as well. Using an UNO no luck and lots of frustration. I can upload using the UNO just fine for a pro mini board but a stand alone chip, nada....I haven't tried using an ISP programmer but I have one in my drawer so I'll get that out when I get home and try it.

I really appreciate your video! It has answered questions I haven't been able to find elsewhere!

Subscribing now!

Thank you, this worked very well and the newest version of the usbASP driver works great too. This was the only video I watched and yet it was the only one I needed. Thank you again, this shit was epic.

Kakushin! Thankyou so much! Incredibly valuable tutorial! Cheers!

After 2 weeks, I could upload a code. Thamk you 👍🙌🙌🙌

Very good .. I can bootloader the microcontroller Atmega328 pu with a QFP32 and compile my sources. Everything works.
Thank you.

I appreciate this. I always wondered how to go about flashing the chocolate chip variety of this MCU

[jakecook]

Worth noting... I am using an arduino Nano as a programmer and have been successful, both on breadboard circuit and prototype pcb. Both successful, in fact using a Mac it has been almost impossible to update the driver for the common usbasp programmer that is sold online - so I kinda had to go with a Nano, or other arduino board as the programmer.

Anyway! It's :D Nice job Kakushin! Cheers!

Thanks for this video, I replicated this circuit but made a slight change to it with a soldered copper veroboard instead with predrilled holes at the right pitch . Changed to an external LED in series with a 1.5K ohm resistor works perfectly fine with ICSP (SCK) PB5 port pin (13), [You don't need to modify the original sample Arduino Blink Sketch] you also get a visual indication from the LED that it is writing to the FLASH, I had one USBasp programmer work function OK with this circuit, but another of the very same type failed to detect the chip signature, so that is another aspect that one has to bear in mind, to successfully make this particular circuit work.

Great video! It helps a lot and ist well done. Thank you very much!

[cw_uk]

This video was just what I needed, thanks :)

[prodsefv]

thank u for the video it really helped

[XTomsenX]

Very useful video, thank you. Do u have another one, how to make a board with the Atmega328 chip - i mean what it needs to standalone?

[hervemarie]

Thank you for this very informative video.All your demonstration worked like a charm for me !! For that THANKS A LOT. It gives me several ideas for projects :-) Unfortunately, at this date, the Atmega 328, among others, is out of stock for a very long time at the main suppliers (Farnell, DigiKey, Mouser, ..) :-( The shortage of components, even simple, does not reassure us about our future 😞 Take Care

You can also use Microchip Studio 7 to burn the boot loader.

Hello Kakushin
Why do you burn the bootloader first? I thought the bootloader is not necessary anymore when programming via ISP.

I thought when programming via ISP a previous burned bootloader will be deleted and the whole program memory is now available.
Best regards, Tom...
