Littlefs on RT1064 internal flash.

[emvlabs]

I found the Littefs example on SDK.

But It use the External Flash through the FlexSPI.

I would like to use the Internal Flash.

3MB for Program Area.

1MB for littefs Area.

In the lfs_support.h

#define EXAMPLE_FLEXSPI FLEXSPI
#define EXAMPLE_FLEXSPI_CLOCK kCLOCK_FlexSpi
#define EXAMPLE_FLEXSPI_AMBA_BASE FlexSPI_AMBA_BASE

FLEXSPI => . FLEXSPI2

FlexSPI_AMBA_BASE => FlexSPI2_AMBA_BASE + (3MB address)

Is it possible ?

Hello emvlabs@gmail.com‌ , 

Please refer to the following community document, here you will find a detailed explanation of all the modifications that you need to make to one of the SDKs examples to use the on-chip flash as NVM. 

RT1064 use on-chip flash as NVM 

Have a great day,

Hi ChoonGyeong Lee,

Thanks for your reply.
1） Is there any way to read and write an internal flash?
-- Yes, the RT 106x series MCU contains the
FlexSPI NOR Flash Driver API which is able to implement a variety of flash operations like erase, program, etc. You can find detail information about the driver in the RM. In further, I've attached a demo project that presents how to utilize the ROM driver.

Have a great day,

Hi ChoonGyeong Lee,

Thanks for your reply.
1) Did you attach a demo project?
-- Yes, just as the below figure shows. And I think the demo project still be held in the moderation queue, so it's invisible for you.

Have a great day,
