[K20D50M]: Looking for a simple USB bootloader for K20DX128VFM5

My existing product needs adding bootloader for image update purpose only. There is only one USB interface on it so I think it makes sense to use USB to receive/update FW image from PC as host. My app size is around 60KB and hope bootloader won't take too much memory.


Product uses K20DX128VFM5 MCU and development GUI is IAR only.


I went through AN4370SW but not sure if it can be used as straight forward as one to K20DX128VFM5, or any porting guideline including app vector table redirection exists?
