i see you were on discord, for the next user, you need to load the overlay to disable auto-loading:

/overlays/k3-am625-beagleplay-bcfserial-no-firmware.dtbo

I have a new utility at https://git.beagleboard.org/beagleconnect/cc1352-flasher on the from-20230521 branch that is better at supporting multiple devices and has cleaned-up commits. I'm not sure what else I need to do to make it user-friendly and where I can promote it as an alternative upstream to cc2538-bsl.py.

oh man, just realized this was on github, not git.beagleboard.org. the UI should have figured it for me.
