AHRS EK3 not started error message. i turned off pre arm, but can’t arm noticed this was at one time a bug however i do have my compass working. This is with the KAKUTE F7 rotated arrow pointing up 270. Not sure how to disable.
The message, “EKF3 not started” can appear if AHRS_EKF_TYPE = 3 but EKF3_ENABLE = 0. The solution is to enable the EKF (EKF3_ENABLE = 1) or switch to EKF2 by setting AHRS_EKF_TYPE = 2.
Odd to get that error. AHRS_EKF_TYPE = 3 and EKF3_ENABLE = 3 are default for beta7 on the Kakute F7 (have a couple). And previous versions going back awhile.
