Hello sudhakar p:

For loading the firmware from an external memory unfortunately there is no example available for K64.

Basically you need at least 2 things: external flash driver + internal flash routines.

- You need to implement the external memory driver.

- For the flash routines you can take the driver C90TFS integrated with KSDK: C:\Freescale\KSDK_1.2.0\platform\drivers\src\flash\C90TFS

For other bootloader interfaces (e.g. UART, USB HID), you can download Kinetis Bootloader (KBOOT):

This includes a KDS project for K64.

There are other examples about bootloader implementations for your reference, such as AN2295 (UART bootloader):
