MKL17Z - How to initialize user flash data at compile time

sys — Mon, 11 Jan 2016 12:43:36 GMT

Hi all,

I'm using MKL17Z256VFM4 with KDS 3.0.0. I would like to know if there is a way to put default values in the flash user block at compile time.

For understanding, I would like to do like I do with CodeWarrior 6.x with the "@" directive, for example:

const uint EEDefault[2] @ 0xE000 = {

0x0001,

0x0002

}

In this way I'm sure that after downloaded the executable, in the address 0xE000 I have the value 0x0001, and so on.

Is it possibile to do stuff like this with KDS and MKL17Z in similar way? I know it's not possibile with MKE02Z, but these two micro are quite different, so maybe there is a way with MKL17Z?

It would be good, so I dont need to make my own init-flash for every project.

Thanks in advance!

Sandro

Hi Sandro,

Please take a look to the following document, it explains how to place code and data in specific ROM and RAM addresses:

Hope it helps!
