CCS/CC1310: CC1310 ODA implementation

Part Number:CC1310

Tool/software: Code Composer Studio

Hello

I like to add our Sensor an OAD Feature. We use the CC1310 Chip and only internal Flash memory.
This should be no problem, since the App size is small.
I'm working atm with the rfWsnNodeIntFlashOad Client/Server. I can do FW updates with no troubles via Sub1Ghz.

Now I want to use the rfWsnNodeIntFlashOadClient as the fixed Image A (to update the Image B).
Image B is the real Application for the sensor.

How I can switch from Application B to A?

I think i have to change to Bootloader Bootsequence, but whats the best way to to this App-switching?

Thx
