BCM9WCD1AUDIO is not supported by default in SDK 3.5.2.
What we can build as a platform is listed in <WICED-SDK>/platforms/.
You need to get appropriate platform files(patch) for other platforms.
By the way, N02 uses BCM43362 with STM32F4.
So BCM943362WCD6 is close platform.
But I'm not sure it works as expected on N02.
But as per the WICED site: WICED Software Development Kit 3.5.2 is now available... (under Hardware Platforms section) it is reported that this platform is supported but of course I don't see the platform folder for this platform in either the 3.5.2 installation in .exe or as .7z formats.

In addition based on your info, I don't know if BCM9WCD1AUDIO or BCM943362WCD6 is the closest match to the SPIL SSB-WM-N02 EVM board. Can't it be straight and clear with a patch available in name of SPIL (like done by Murata or others on their website?)
Aren't there any ready to use SoCs that work straight out of the box flawlessly? We have tried USI WM-N-14 and there again we had wifi range issues and lacked tech support. So we decided to evaluate SPIL but from SPIL's website (SPIL) there is hardly anything useful that can skimmed out!
I don't know why the README contains BCM9WCD1AUDIO as a platform.
What I know is just no directory for N02 found under <WICED-SDK>/platforms/.
So you need to get appropriate platform files.
Could you ask your local distributor who provides the N02 module/board?
Both BCM9WCD1AUDIO and BCM943362WCD6 uses BCM43362 and STM32F4.
So I thought they're close. I don't know it works as I mentioned.
