avrdude on raspberry tx/rx is there a way to just set a reset pin in avrdude config?

there's a method using a pipe and python filter to intercept point to fire reset for arduino bootloader trigger over ttyama0

can you not just set a gpio reset pin to use in avrdude config somewhere?

guess would have to be quite target (rpi) specific, knowledge of how to fire the gpio pin required.

i guess a script name to fire at reset point might work, then whatever target can write a script to fire whatever reset pin?
