I am using atmega328pb. I have developed application code and bootloader code to update the application code in future.
So, for now I am uploading the bootloader code first in the MCU and then application code with -D command, so that the previous code will not get deleted.
But, I want to merge both the hex file so that while production, I can upload both files at once.
So, how can I do this.
Thanks in advance.
