PGA411Q1EVM: A noise is introduced when an arduino board is connected

Part Number: PGA411Q1EVM

Hello,

I'm trying to read the Angle data from a PGA411Q1EVM via SPI communication. The motor being used is the REMY HVH250 3-phase permanent magnet motor. So far I can read the angle through the GUI without any issue. And no noise is present in the Data Monitor of the GUI. There are no Fault flags triggered. 

But as soon as I connect my Arduino Uno to the SPI pins of the EVM module there is a huge noise introduced. I tried using several Arduino boards but the issue still remains. 

The pins I'm connecting are,

NCS, SCLK, SDI, SDO in the J11 header with their respective counterparts in the Arduino Uno. Also, I'm connecting FAULT and NRST pins to two digital pins in the arduino board.

Any insight into this would be highly appreciated, 

Regards,

Ranitha
