Hello,
I have an Arduino Nano using a ATmega 328PB (not a 328P) and I have to burn a bootloader on it.
The common examples using the "Ardnuino as ISP" with a UNO as the programmer (such as this one: https://www.arduino.cc/en/Tutorial/ArduinoISP) does not work when the processor is a 328PB and not a 328P.
How to proceed to burn the bootloader on a Nano with a 328PB ???
Preferably with the Arduino IDE (very easy to use) or with another software, maybe ATMEL Studio ??
Thank you very much !
Hi,
... well, every time.. "there collide old against new"... 
1) You never can program a device without an programmer - it's a hardware with will be used as a source (be programmed) the target device.
This hardware can be an EPROM-programmer, which understand the device
It can be a controller board, which has an programming interface onboard.
Well, the AVR µC has an ISP interface with that you can program this µC.
You can use this ICE-PCB (the cheaper version of the ICE), without the enclosing as well you need to purchase the interface cable if you have not:
The ICE with enclosing and with an interface cable:
Or you can use the STK500, or STK600 development board:

https://at.farnell.com/microchip/atstk600/avr-avr-studio-4-jtag-starter/dp/1562235?st=stk600
2) You needs the software, an IDE e.g. Atmel - Microchip studio:
https://www.microchip.com/en-us/tools-resources/develop/microchip-studio
(with this Microchip studio you can use the STK600, the ICE, the STK500)
Actually I work with the STK600 and the ATMEL studio Version 7 (the link above you can download it).
The Nano (on top in this image the Nano clone with the blue board) has no bootloader.
So, then I extracted the bootloader from the original Nano (in the image -> the Nano with the green board) (the HEX.file) and than I programmed it into the Nano clone.
After that you can easily work with the Arduino IDE as well. Just connect it on an USB port (virtual COM port).

With the Arduino IDE you can use the STK500, the ICE (but not the STK600)
3) You need the right bootloader for your µC:
please read the differences 328/P --- 328PB:
https://www.microchip.com/en-us/application-notes/an42559
A big solution you have as well is to use the MPLABX IDE with its tools, compilers.
https://www.microchip.com/en-us/tools-resources/develop/mplab-x-ide
This was the overtop about an development tool.
-
A much more cheaper one you can work with an starter kit, like this ATMEGA328PB-XMINI (using it with the MPLABX tools):
https://www.microchip.com/en-us/product/ATmega328PB
https://www.microchip.com/en-us/development-tool/ATMEGA328PB-XMINI
Please read the manuals.
So, what do you want to do?
With an Arduino IDE, you are not so flexible.
With the tools from Microchip (Microchip has bought ATMEL) you can work with very well.
I wish you the best!
