Program Flash and NV data

enzino — Mon, 29 Oct 2012 09:17:17 GMT

Hello,

I have a question about program flash. I'm using K60 with 1024KB of flash memory.

I want to use a little part of this to store some data.

No problem to write and read the flash, my problem is that when I reload my program with debug (or run) command, in internal flash configuration I find the entire flash memory erased.

I try to reserve a portion of flash (in build options) creating a new area from 0xF8000 (the last sector) but it's the same.

How can I do to avoid that my data is overwritten? Is it possible?

Thank you

Hello,

Yes, it is possible.

Are you using P&E Multilink/CodeWarrior?

If so, then this might help:

Depending on the amount of Flash you want to preserve, using an Eclipse target task might be a faster solution.

Hope this helps,
