Export Bootloader and Sketch for Batch Upload

Using Arduino Avrdude, stk500, Bootloader issues
1

Hi there,

i have a PCB here with a 34u4 chip. I know how to program the bootloader to it and the sketch afterwards. I have zero experience in coding.

But i am looking for a way to maybe export to bootloader and sketch from a ready pcb to burn them to the pcb in maybe one step. Ideally with a batch so i can do one after another.

Any Tipps where to start or what would be the easiest way to achieve this goal? Oh yes, i use a USBasp for programming.

Thanks in advance!

If you use "Export compiled binary" in Sketch menu in IDE, you get hex files next to your ino file. One of the hex files is "_with_bootloader.hex". You can flash it with avrdude from command line over the programmer.
