Sony Spresense - Failed to get info off device - Can't write KX126 CNTL2 register

Hello!
We are trying to acquire accelerometer readings from the Sony Spresense board and we are met with the following errors:

And the board succesfully connects to the platform, but when acquiring accelerometer data we are prompted with the following error:

The board was flashed with the firmware downloaded from Sony's Spresense - Edge Impulse Documentation and flashed using a Python 3.7 venv.
Any clue on why this is happening? Thank you.

Hi @mihnea.stoica27,

Which accelerometer shield are you using?

We’ve used this shield to add an accelerometer to the Spresense board: https://www.chip1stop.com/USA/en/view/dispDetail/DispDetail?partId=ROHM-0170579&cid=c1s_sony_spresense_SPRESENSE-SENSOR-EVK-701

I only have it connected to an Extension board, i presumed it had a built-in accelerometer.
Thanks for the input.
