+# The official [OSHChip CMSIS-DAP programmer] provides also
+# a MBED-type Mass Storage flashing mechanism - copying
+# a hex file to the external "drive" flashes the firmware
+# to the attached OSHChip.
+
+# However this MSD flasher expect the hex file to begin with the
+# "Extended Linear Address" (e.g. ":020000040000FA"); this happens
+# automatically if the firmware is >= 64kB, but MBED online compiler
+# does this always. ARM GCC suite does not. Hence this script.
