im not sure if this is the right section for questions regarding this Evaluation Board so admins feel free to move it Slight smile

I am currently trying to talk to the AD74413 via SPI (raspberry) and im havint trouble with the SDI line. It somehow is tied to ground (meassured it with Multimeter/Oszi). What i can tell from the Datasheet this doesnt make any sense ? What could possibly be the Problem?

Thanks alot,
