The CYW43455 and CYW43012 EVKs are currently not fully supported within the the current SDK. The CYW43455 has been released as a chip to the broad market, but the second generation EVK for this board will be supported in a new release of WICED (not sure exactly when it will be released). The CYW43012 will be supported in that release as well. At this point, it's best for you to reach out to your local CY Sales and or distributor so they can line up support for you on both products.
Do i have to contact local CY sales for the reference circuit? I am currently working on the schematic and layout. But i cannot find the full datasheet and reference circuit, thus cannot continue schematic. Would you please let me know how to get the reference schematic and layout guide line(sample)? Thanks in advance.
You will need to let me know where you are located. In your profile the city you list does not match the country.
