# Script used to flash, prepare and configure Minnowboard MAX.
# Compatibile with both (32-bit and 64-bit) versions.
# Configuration file in $TL_IP_CONF is required; format is:
#   <IP address> <SDMUX>
# It leaves CONNECT_CNT in sysctl.result to be later used by minnow_run.sh
#
# Synatx is: minnow_prepare_conf_flash.sh $SDMUX $IMAGE
