Does flash swap work on chips with FlexNVM?

[c_johnson]

The NXP documentation talks about flash swap not working on chips that have FlexNVM "Enabled".  As far as I can tell you can not disable FlexNVM.  Does this mean that if you want to use flash swapping that you must use a chip that has only program flash?

I am specifically wondering if it is possible to do flash swapping for firmware update on a MK66FX1M0VLQ18 chip.

Thanks,

Chris

Hi,

No, it is impossible. Please see the reference manual section 4.2

For the devices containing program flash and FlexNVM:
• The program flash swap feature is not available.
