Hi,
I´m using a LPC1850 which is booting and running the software application from SPIFI. But my application need to erase and programming some sectors of SPIFI memory while running (like IAP commands). Anyone knows how to do this?

Download the peripheral driver library from here:

It contains a SPIFI library and a description of the API.

I tried this once. I found that when I was running from SPIFI, accessing the SPIFI library killed the program. This makes some sense to me. In a program running from RAM I was able to write to the SPIFI using the library. I suspect, though I haven't tried, that you need to be sure you are not running out of SPIFI when you do the write. So try putting the code to program the SPIFI in RAM?

Yeah,
I tried this one too, but without success. So I am also interested.
