ISM330 SPI not working

Hi,

I'm trying to get the SPI interface with the ISM330DHCX to work but it seems that the SDO pin can't reach logic high levels.

The above has SCL in blue and SDO in red.

Above is my hardware setup, vdd and vddio is hooked up to 3.3V on the Nucleo.
I've been able to get this to work with I2C but haven't with SPI. Any help or advice would be appreciated
