Hi,

Thank you for reaching us,

Could you clarify a bit your request? Is it something like use the free flash memory to store some data?

If yes you could have a look to the nvs_internal example located in your SDK in the drivers folder.

This example shows how to use the Non-Volatile Storage (NVS) driver to read and write data to on-chip flash memory.

regards,

Hi,

I would like to design an A/B patition scheme. So I would like to know whether I could write the new image to the B partition when App running in A partition and then switch to B partition after reboot.

Hi,

Ok that's clearer now, we have the right example for that : basic_ble_oad_on_chip provide in the SDK.

I suggest you to read the user's guide related to this chapter: TI Over-the-Air Download (OAD)
