  * An issue where the axis state machine would jump in and out of idle when there is an error
  * There is a [bug](https://github.com/ARM-software/CMSIS_5/issues/267) in the arm fast math library, which gives spikes in the output of arm_cos_f32 for input values close to -pi/2. We fixed the bug locally, and hence are using "our_arm_cos_f32".
