CC2642R: multi role stack library pre-compiled or linked

Amit Edvy

Part Number: CC2642R

Hi,

We used to develop our app based on the simple_peripheral_oad example, and now we're starting a new project basing on the multi role (SDK 3.10).

I know that there are two ways for the ble5 stack library to be included in the project-

1. linked library

2. pre compiled library

I'd like to know:

1. which of the methods the multi- role is using (and how could I determine it using the ccs, in the future)?

2. how would it influence the size of the final image? the sizes on the map will include the size of the stack library, for example?

3. how would it affect the OAD process (will I need to upgrade the stack library image separately, or upgrade the app and the stack library a one image only?)

I'd appreciate your help,

Amit

Hi Amit,

1. Multi role uses precompiled library. More information in the BLE5-Stack User's Guide: dev.ti.com/.../software_architecture.html

2. Using this build configuration yields additional flash footprint optimizations by the linker since the application and stack can share contiguous flash pages. See the example project’s README file for the available project build configurations.

3. For CC26x2 we only support upgrading the app and stack library at once in one image.

Did you see we have step-by-step instructions for adding OAD to the multi role project in the SimpleLink Academy BLE OAD lab? (link: dev.ti.com/.../ble_enhanced_oad.html )
