Internal flash storage in TI-RTOS way

Vladimir Aparin

In standard TI-RTOS documentation memory access described only for external flash.
I want to store in internal flash CC13xx ID number of my device.
How I can do it in RTOS way?

There are 2 questions:
If I need unchangeable ID I can write it on full device programming (on manufacturing).
I want to read only in my program.
If I need to store changeable configuration, then I have to write to internal memory too.

How I can do it?

Last - 2.15.

If you can recommend another version of TI-RTOS, please advice it.

Hi Vladimir,

You can use the Flash APIs in the cc13xxware driverlib.

Fyi...We'll be releasing 2.16 in a week or two. It will contain a new NVS module that allows you to manage internal flash. It is a "preliminary" module and subject to change based on the feedback we get.

Hello Tod,

Can I give some recommendations from my customers and me about required functionality?
1) Writing in FLASH like EEPROM without additionally required preliminary erasing of sector. I think it may be implemented based on flash API in CC13xxWARE with additional wrap.
2) Protection for sector. Some sector may be readonly from user application (1 time programming when device flashing). It will be great for device ID.
3) Protection for TI-RTOS configuration in CCA. Last sector of Flash where customer wants to store their configuration TI-RTOS store configuration too. Customer need to restore TI-RTOS configuration when rewrite in CCA. So TI-RTOS self-protection is good idea.

Best regards, Vladimir

Thanks. The first one is possible with the NVS module. I've added the protection request for a future release.
