Designing IIC boot loader on Kinetis E

Many applications or products have to upgrade firmware in the field to fix some bugs found, or sometimes to enhance performance. Most of them do not use the dedicated debug interface, but only use the communication interfaces, such as UART, USB, IIC, and so on. In this case, a serial boot loader is required to upgrade firmware via one of the communication interfaces without debugger or dedicated program tools. This application note guides how to design boot loader on Kinetis E series MCUs with IIC interface.
