Kinetis Drivers - fsl_flash versus fsl_ftfx_flash

[deniscollis]

I see that some of the demos and/or examples use the fsl_flash driver, and others use the fsl_ftfx_flash driiver.  At first glance the APIs look the same.  However, the underlying code is different.  For example, fsl_flash has a mechanism to copy and execute the driver functions from RAM, which is not present in fsl_ftfx_flash.

Which is preferred?

Hi Denis Collis,

   fsl_ftfx also copy the run command to ram, please check this code:

When you use the flash, please copy the launch command code to RAM.

Wish it helps you!

Have a great day,
Kerry
