IAM 20685 HP SPI response error bits always set

By kshankaraevaai , 21 January 2026

Hello, I am trying to read spi who_am_i data from 20685HP IMU sensor and see all the data packets received from the sensor have the ERROR bits RS1 and RS0 always set to one. How to find what error actually happened to trigger this state? Is there any register to get to know about this? Also I do not see linux drivers for this device on your github, could you share the drivers?
