ADE9153A Shield not detected

[NAGHO]

Hi,
I was testing the ADE9153A shield ( EV-ADE9153ASHIELDZ ) with Arduino UNO and i keep getting this message
" ADE9153A Shield not detected. Plug in Shield and reset the Arduino "
==> I tried different possible CS pins and SPI speeds and the communication still fails .

This is the link for the EV-ADE9153ASHIELDZ user guide :
https://www.analog.com/media/en/technical-documentation/user-guides/ev-ade9153ashieldz-ug-1253.pdf

The sketch i have been using :

#define CS_PIN 8 //8-->Arduino Zero. 15-->ESP8266

// Different alternatives for pin 8 also don't work

#define USER_INPUT 5 //On-board User Input Button Pin
#define LED 6 //On-board LED pin
