FSL has a great application note AN4379 regarding MSD device bootloader for Kirin3/Flexis JM/Kinetis K60 w/ CW, written by Derek Snell.
Additionally FSL also offers USB source for MSD device for emulated RAM and external SD card (via SPI bus) for multiple platforms.
I am looking for MSD device bootloader for KL25Z for IAR toolchain.
Is there any update for AN4379? I just want to make sure I am not going to re-invent the wheel on bootloader, ‘cause application development is my focus.
