How to preserve second block of flash during debugging

paulderocco — Tue, 11 Nov 2014 23:21:31 GMT

I'm using a FRDM-K64F board, and I'd like to store some non-volatile data into the upper flash block. How do I configure the KDS debugger so that when I load my code, it doesn't erase the entire flash? I'm using the Multilink Universal FX and JTAG.

Hello Paul:

Maybe this tutorial is what you are looking for, explained by colleague Erich Styger:

That works--thanks.

It is, however, kind of an ugly hack to modify a readonly file deep in the KDS system, though. It would be really nice if the developers added a way to do this on a per-project basis, as was apparently the case in the old CW.

Hi Paul,

yes, I agree this is only a hack and a workaround. I already have asked P&E if they could add that to their gdb solutions. As a customer of their Fx probes, for sure you can ask them too, so P&E knows that there is a need for this functionality.

Thanks,

Erich
