ChatGPT came up with this to make the change persist.

# 1) Create a minimal plugin dir with just "generic"
mkdir -p /mnt/state/root-overlay/usr/lib/ModemManager/generic-only
cp /usr/lib/ModemManager/libmm-plugin-generic.so \
   /mnt/state/root-overlay/usr/lib/ModemManager/generic-only/

# 2) Add a systemd drop-in to change ExecStart
mkdir -p /mnt/state/root-overlay/etc/systemd/system/ModemManager.service.d

what board should I use?
Answer
To determine which board to use, let's consider the options provided in the documentation.
You can check out the different boards at: index.rst.
This document lists various boards, including BeaglePlay, BeagleBone, PocketBeagle, and BeagleBoard, each with its unique features and purposes.

Broken AM62x PRU code with dmesg log
# This Makefile tries to provide some defaults for building single-file programs on Beagle
# platforms in part by adding an additional suffix ahead of the source file extension. The
# original purpose was to provide ability to run these programs in the Cloud9 IDE environment.
#
# Optional definitions
#
# TARGET - executable to create (currently supports single .c, .cpp or .asm source)
# should have .<proc>(<n>) extension (lower case, check below for valid options)
# without TARGET, as of now, we don't have any build targets
# TODO: work with a list of targets, rather than a single file
