I have a problem when loading the bootloader into the Atmega328PB-AN custom chip, I use an arduino nano as a programmer. When I upload the code via Arduino to Atmega328PB-an it works normally, when I connect usb to computer it connects Ch340G to computer. When I upload the bootloader in arduino ide and use MiniCore library it says it will upload but when I try to upload the code to Atmega328PB-an it throws :
avrdude warning: programmer is not responding; try -xstrict and/or vary -xdelay=100
avrdude error: unable to open programmer urclock on port COM9
Core 2.0.11 and optiboot please!
I am new in this, You mean MiniCore version 2.0.11? and what is optiboot?

Please, explain your latest post. Does that mean you were successful?
No, it starts saying:
avrdude error: programmer is not responding
avrdude warning: attempt 1 of 10: not in sync: resp=0x00
....
Yes! In version core 2.0.11 bootloader is optiboot! Please reprogramm bootloader!
I use version 2.2.2 where it is also. I have uploaded the bootloader according to everything, but now it says this when I try to upload to Atmega328PB-AN:

avrdude done. Thank you.
So the problem is in the CH-340 converter
Like in the wiring or in the ch340g itself? Should I try replacing the ch340g?
It's hard to say, I would take a supporter USB-UART converter and feed it to the RX/TX pins
I didn’t see 1k resistors on the diagram between RX-CH340 and TX-328PB and similarly TX-CH340 RX-328PB? they are?
look at the RX-TX circuits in the nano diagram, do they match yours?
R6 and R7 1K ohm, I'll try replacing the ch340g and then I'll see and let you know according to what you sent I'm all good. Thank you very much for your help.
I've tried 2 things:
- I connected the arduino to the computer and sent data to it via serial communication ( serial monitor ) , the Rx diode flashed.
- I uploaded the code via Arduino Nano ( ISP ) to output the "hello" from the serial monitor, the Tx diode flashed and it output.
So I don't know where the fault is anymore, I'm wondering if it's a fault with the reset circuit (because some places have RST* over 100nF and some places have DTR* over 100nF) that the ch340g would not reset the Atmega328pb. So it couldn't bootloader there and that's why it says:
avrdude error: programmer is not responding
avrdude warning: attempt 1 of 10: not in sync: resp=0x00
