How read/right user variable value in internal flash?

gustavo_costa — Fri, 20 Dec 2019 15:57:30 GMT

Hello people!

I am a newbie to this processor (IMX RT 1060) and need to perform the write / read values from internal memory.

This operation is necessary as I need persistent values for the application.

By downloading the SDK from the site and importing into MCUXpresso IDE I saw that there are no examples. I didn't enter "fsl drivers" to manage it either.

Would anyone have a tip, suggestion for this question?

Any help is well appreciated.

Thank you!

Hi Gustavo Costa,

Thanks for your interest in NXP MIMXRT product, I would like to provide service for you.

Please download the RT1060 SDK code from this link at first:

Welcome | MCUXpresso SDK Builder

As you know, RT1060 don't have the internal flash, then you need to use the external flash.

So, after you download the SDK code, you can refer to this code to write, read, erase the external flash:

SDK_2.6.2_EVK-MIMXRT1060\boards\evkmimxrt1060\driver_examples\flexspi

Wish it helps you!

Have a great day,
Kerry

Hello,

Look at app note AN12564 (Implement RWW on i.MX RT Series)
