Hi TIA,
First KV46 needs to be supported by both MCUXpresso IDE and SDK.
when download SDK , we must be attention to set Toolchain as MCUXpresso IDE. I know many customers met build error because didn't define the correct toolchain.

after you install SDK, you can create a new project with referring attached video. this this not for KV but the method is the same.
Have a great day,
Jennie Zhang
