LP-CC2652RB: Migrating from LP-CC2652RB to CC2652P based custom board

Part Number: LP-CC2652RB
Other Parts Discussed in Thread: CC2652P, , CC2652RB, CC1352P, Z-STACK

Good morning.

I'm developing a custom router firmware testing and debugging on LP-CC2652RB board. Now i am at the point in which i'd like to test it on some dozens of custom boards based on CC2652P chip that we have got.

My starting project was the zr_genericapp_LP_CC2652RB_tirtos_ticlang, until now i used it with its syscfg file.

I'm trying to follow the Custom Hardware document, but i could not edit "Project → Properties → General → Project → Variant" which is grayed out. picture related:

The infobox dialog says that i have to configure it on my project's syscfg, but i could not find the suitable field to edit in it.

Any advice on how to reach the migration to the CC2652P chips?

Thank you in advance

Roberto

    Hello Roberto,

    I do not recommend that you try to modify the zr_genericapp_LP_CC2652RB_tirtos_ticlang project to accommodate a CC2652P.  Instead, please import a new CC1352P-2 ZR GenericApp project and migrate your application changes accordingly.  Reference the Z-Stack Migration Guide for additional information.

    Hello Ryan.

    Ok, i'm going to try that way

    One doubt, i see that the SDK doesn't have specific example projects on CC2652P, so we have to start from the CC1352P-2 (why not CC1352P-4?) genericApp project. However, i see on the CC2652P and CC1352P datasheet some differences, in particular in the sensor interface (the DAC, the comparators...). So it is not perfectly clear to us how can it be equivalent to have the same starting project for both. Even if i had understood that CC2652P is a ''subset'' of CC1352P. But why TI does not provide a specific CC2652P starting project in the SDK?

    Thank you again

    Regards

    Roberto

    You can use CC1352P-4 Z-Stack examples for +10 dBm output TX power.  The sensor controller of both devices is the same even if this is not adequately reflected in the block diagram of the datasheets.  CC2652P-specific example projects are not provided since the CC1352P is operational equivalent except for the Sub-1 GHz radio.
