Flash K40 without disrupting FlexNVM partition and data

Is there a way to flash a Kinetis part with Flexmem, without disrupting the FlexNVM partition information or the data stored in it?

I'm assuming you created a partition, loaded your code and want to update your code later on:

You can use any of our available bootloaders, it should not modify your FlexNVM partition provided you specify it writes only in the D or P-flash partition (app code)

I'm actually in the middle of working on my project and flashing updates with my BDM and debugging, it's just a pain that it resets the data in the FlexNVM. I suppose I could do what you suggest with the bootloader and just debug by attaching. Thanks for the quick response!
