# Custom Functions
##########################################################################################

# This file (config.sh) will be sourced by the main flash script after util_functions.sh
# If you need custom logic, please add them here as functions, and call these functions in
# update-binary. Refrain from adding code directly into update-binary, as it will make it
# difficult for you to migrate your modules to newer template versions.
# Make update-binary as clean as possible, try to only do function calls in it.
