To assist in finding Dev path for device use before flashing use:

#!/bin/bash

for sysdevpath in $(find /sys/bus/usb/devices/usb*/ -name dev); do
    (
        syspath="${sysdevpath%/dev}"
        devname="$(udevadm info -q name -p $syspath)"
        [[ "$devname" == "bus/"* ]] && exit
        eval "$(udevadm info -q property --export -p $syspath)"
        [[ -z "$ID_SERIAL" ]] && exit
        echo "/dev/$devname - $ID_SERIAL"
    )
done

Replace "dev/ttyACM1" below with path matching your device.

sudo /usr/local/bin/bossac -i -d -p /dev/ttyACM1 -e -w -v -R --offset=0x2000 out/klipper.bin
