Worked on the geerlingguy/linux repository, focusing on improving the reliability of the IIO/IMU driver for the ICM42600 sensor. Addressed a critical issue where invalid temperature data, occurring when the accelerometer and gyroscope were powered down, previously returned an -EINVAL error. Modified the driver to return -EBUSY instead, aligning error signaling with Linux kernel conventions and enabling the system to retry data acquisition in a more appropriate context. This change enhanced the stability and reliability of IMU readings. The work involved C programming, device driver development, and a deep understanding of kernel-level error handling within the IIO subsystem.
