Over the Air image upgrade on CC3200

Other Parts Discussed in Thread: UNIFLASH, CC3200, CC3200SDK, ENERGIA

Hi,

I am currently working with CC3200 Launchpad for our project. We plan to use CC3200 in our project and has a requirement for over the air upgrade. We can download the image with Wifi interface but have no clue how to flash image on external flash from our application code (currently it can be done using uniflash). I have couple of question related to that, hope expert can answer them.

1) Is it possible to keep two images in the flash. (Factory Default  and Current) and allow to switch between them?
 If yes, how?

2) Is it possible to only upgrade the code that we are writing instead on single binary that bundles TI RTOS and our application code? If yes how?

3) Is it possible to partition external flash. One partition store TI RTOS and other store our application images (multiple) and we write logic to determine which application image TI RTOS will run?

4) This is possible with sparkcore (using STM microcontroller + CC3000). We want to replicate the procedure with CC3200 as it has integrated microcontroller. Looking for your advise please.
