User segment in flash in Kinetis 64 (frdm kinetis)

Question asked by Mikael Elharrar on Feb 2, 2017


I'm using freedom dev. board FRDM K64 and would like to define a user segment in my flash in order to store there some application data.

Someone knows how to do that ?

Because the main constraint is to avoid the (future) bootloader and the jtag to not erase this segment.

For your information I'm using kinetis studio.

One important other question:

- What is the minimum size of a flash segment ? I see 4K, but is it possible to write only some bytes only or I need to erase all the block each time I want to write on it ?
