+/*
+ * This example demonstrates how to use to update the firmware of the Arduino Portenta C33 using
+ * a firmware image stored on the QSPI.
+ *
+ * Steps:
+ *   1) Create a sketch for the Portenta C33 and verify
+ *      that it both compiles and works on a board.
+ *   2) In the IDE select: Sketch -> Export compiled Binary.
+ *   3) Create an OTA update file utilising the tools 'lzss.py' and 'bin2ota.py' stored in
+ *      https://github.com/arduino-libraries/ArduinoIoTCloud/tree/master/extras/tools .
+ *      A) ./lzss.py --encode SKETCH.bin SKETCH.lzss
+ *      B) ./bin2ota.py PORTENTA_C33 SKETCH.lzss SKETCH.ota
+ *   4) Upload the OTA file to a network reachable location, e.g. OTAUsage.ino.PORTENTA_C33.ota
+ *      has been uploaded to: http://downloads.arduino.cc/ota/OTAUsage.ino.PORTENTA_C33.ota
+ *   5) Perform an OTA update via steps outlined below.
