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 )
