CC3220MODA: Can CC3220MODA replace CC3235MODA from a FW standpoint?

Part Number: CC3220MODA
Other Parts Discussed in Thread: CC3235MODASF

Hi team,

My customer is wanting to know if the CC3220MODASF will work in place of their CC3235MODASF. We know it will work fine from a hardware standpoint, their concern is potentially managing two separate firmware builds for the two different processors.

Boiled down- their question is:

Can the same build output from a CC3235-based CCS 10/11 project function correctly on a CC3220 device?

Assume two boards, one with a CC3235MODASF and the other with a CC3220MODASF.

Will the same SLI file work to program both boards in manufacturing?
Will the same TAR file upgrade both boards over-the-air?
Is it possible for application software to tell the two boards apart during runtime using some sort of SL API call or hardware register inspection?

Thank you!
Lauren

Hi Lauren,

This approach is not possible. You will need to divide production and OTA image into two different streams. Because CC3220 and CC3235 uses different ServicePack.

1. This is not possible due to different ServicePack.

2. This is not possible without changing logic inside OTA code.

3. Yes this this possible. Identify type of device and use different sl_ API calls for each device.

Hi Lauren,

Adding on to Jan's comment. You can identify the part using the code from section 3.5 in the network processors guide:
