MQX FILE I/O

Hi everyone.

I use K60 and MQX 4.0.

There is no external NAND flash on my board.

I want to save configuration information using the internal NAND flash.

How to store configuration information using the internal flash?

Please Help Me!!

Have a look at flashx

flash_hdl = fopen(“flashx:”, NULL); // Open the flash device

example project at

C:\Program Files\Freescale\Freescale MQX 3.8\mqx\examples\flashx

Hello,

internal flashes are usually of type NOR.

Does it really matter, he wants to store his configuration data and flashx will solve the problem it may not be NAND flash but it will be easier to write to (NOR allows random-access, NAND allows only page access) I was just trying to give some helpful advice.
