Thanks you dude, you really save my maybe week or so) I ordered a few nano board w type - c input socket, and its came w some pre - installed program, and I cant load bootloader because avrdude don't recognize the chip. Thanks to you this boards are working now. Best regards !
So do I get it correctly that you have changed the bootloader uploading it using second Arduino as a programmer? I have Nano V3 or whatever it's called with ATMega328PB that I actually really need (to use extra 16bit timer). I can program it without issues from Arduino IDE when I select it as a regular nano board. I just set it as Nano and loaded blink example, no issues. However when I set it as MiniCore PB it's like the bootlader no longer works. I'm using IDE 2.3.2. Edit: OK, I've confirmed that my board apparently was shipped with regular Nano bootloader (or rather the "old bootloader" as it has to be set to that in order to work properly) and in AVRDude I can see it has ATMega328P signature instead of ATMega328PB. I've used the "Export Compiled Binary" option in Arduino IDE and used AVRDude manually with the exported hex. It was set to ATMega328P but of course had no issues to load program for PB and it worked just fine, both the bootloader and my program ;-)
Hello. I am a beginner. I have two arduino UNO R3 clones on ATMega328 chips. First one is on ATMega328P and has a bootloader. Second one is on ATMega328PB and has no bootloader. Is it possible to burn bootloader on that board? I tried to flash "Arduino as ISP" sketch on ATMega328P board and connect it like you show at 6:49, but it does not flash bootloader. What am I doing wrong?
Great video! I bricked two ATmega328PBs before watching your video
No GitHub from me this time. I actually just used OSHWlab instead since it let me post the easyeda files. The GitHub link is Minicore.

Great video once again. Really good detailed info.
Sent you an email a few days back in regards to GM Air Core.
I will have look back at it. I did glance over the email but I it was late at night and then I forgot the next day.
Got it, thanks !
Why I got this error ?
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
Did U solve it?
