K10 - OK to use flash below 0x400?

[chris_f]

I'm running really low on flash space on a MK10DN32VFM5 and am looking for somewhere for a field write-once array.

The device only has 62 interrupt vectors so the space from 0x0F8-0x3FF looks to be unused.

I've tried creating a linker section here, putting an array in it and it seems to work fine.

Is it OK to use this section? I can't find anything in the datasheet that says whether it is or not.

Thanks in advance.

Hi Chris

As long as you respect the normal Flash writing rules there is no problem using free space in the first sector for saving write-once parameters to.
