# Sequans modem firmware update per SDCARD
# 1. copy the sequans firmware you want to use onto an sd card:
#    folder structure should look like this:
#      /sd
#      /sd/NB1-41019
#      /sd/NB1-41019/updater.elf
#      /sd/NB1-41019/NB1-41019.dup
# 2. adjust the CONFIG variables below
# 3. insert SD card into expansion board
# 4. run this script on the device (e.g., via Atom Pymakr)
# 5. wait
