# urclock
#------------------------------------------------------------
# Serves urboot and optiboot bootloaders
# - Reads/writes flash/EEPROM via the MCU bootloader and a serial connection
# - Implements urprotocol, a skeleton version of STK500v1
# - Supports vector bootloaders by patching interrupt vectors during upload:
# + Vector bootloaders run on all parts, no need for a HW boot section
# + Can be much smaller than the smallest HW boot section of a part, eg,
# 256 bytes for ATmega2560 (smallest HW boot section is 1024 bytes)
# - Checks sizes of applications so they don't overwrite the bootloader
# - Keeps the bootloader alive during interactive terminal sessions
# - Provides a 4-byte metadata interface in top flash for
# + Allowing applications to utilise unused flash similar to EEPROM
# + Storing in top flash the file name and its last-modified date
# + Displaying file name and date of the last uploaded application
