LIS2DU12 Self-Test Not Producing Expected Deviation

Hello,

I’m using the LIS2DU12 accelerometer and trying to perform the positive self-test exactly as described in the official application note. However, I’m consistently seeing results that do not meet the expected deviation thresholds, and the self-test fails on all axes.

I’ve double-checked the register writes and delays and followed the datasheet carefully. If anyone has a known working configuration or insights on what might be going wrong, I’d appreciate your help.

Thanks!
