Hi, I am trying to find an application note or some extra information about the following scenario.
MCU will be able to fo firmware updates during a normal operation mode, it will receive binary image using some comm port and store it to external flash memory. After that, MCU should be able to enter bootloader and read from external memory and program application space.
Any application note or direction is welcomed. (Kinetis V series )
Thanks.
Hello,
I'd recommend using MCUBOOT. In the documentation section you will find the necessary documents on how to use this tool. It supports the Kinetis V family. You have the option to use a variety of serial communications and the ability to program or boot from external flash memory.
There is also a getting started page that you can follow to learn how it works.
Best Regards,
Sabina

Can be used on any Kinetis part.
