https://devzone.nordicsemi.com/f/nordic-q-a/114082/secure-fault-when-trying-to-use-bma4xx-driverIm trying to use the BMA4xx driver (via i2c) in 2.7.0. The driver seems to init the device ok but I am getting a &quot;SECURE FAULT&quot; as soon as I do a sensor_sample_fetch . Attached is a minimal project to reproduce the issue.en-USTelligent Community 13Thu, 22 Aug 2024 16:09:00 GMThttps://devzone.nordicsemi.com/thread/499417?ContentTypeID=1Thu, 22 Aug 2024 16:09:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9bb3f600-68ab-4755-baac-09c27b414a12Hakon<p>Hello,</p> <p>can you check lr register with addr2line?
