Production flash programming for MCUs

This application note describes recommended steps for production flash programming on Kinetis K-series and L-series devices. There are different options available for the physical interface used for communicating with the microcontroller to program the flash and also multiple commands that can be used to modify the flash contents.

This application note will discuss the different physical interfaces, flash commands, and provide recommended sequences to minimise issues when programming the flash and also decrease flash programming times. The target audience is anyone developing production flash programming hardware, production flash programming software, or a debugger interface that will support flash programming. Although some of the information in this document might be useful for software-controlled field firmware updates, that topic is not explicitly covered.
