When you write an IoT firmware, there are different things you may never forget to think about… The coming 10 things you can’t ignore are coming from my experience of smart object creation and the associated field experience.
The field experience is unfortunately the real step where you will improve your firmware and discover all you have forgotten when you have written the firmware and tested it in your laboratory. In laboratory everything is perfect.
The following 10 things you can’t ignore when writing a Firmware is a non exhaustive checklist of points to verify before pushing your code to the field. It is also a list of test conditions you can execute to validate a Firmware / device made by a third party.
In the Telecom Design SDK, you have a cflash tool you can use to reflash your firmware from a serial port. This can be usefull to reflash a TD chip from another chip of from an embedded platform like a RaspberryPI.
This peace of code is not really nicely documented, so to avoid spending to many tries, here is the result of my investigations
