RPi3: LSM9DS1 ERROR: Accel #0 fail: TIMEOUT!, vehicle_magnetometer lost

[Pskoog3]

With the latest build the accel/gyro/mag sensor of LSM9DS1 gets calibrated with the correct sensitivity in QGroundControl, but now getting a vehicle_magnetometer lost error as indicated in the following log. Moreover, in QGroundControl it constantly complains for Accel 0 fail: TIMEOUT! By the way I am using a custom sensor board with Raspberry Pi 3.

$ sudo ./bin/px4 -s px4_rpi.config INFO [px4] mlockall() enabled. PX4's virtual address space is locked into RAM. INFO [px4] assuming working directory is rootfs, no symlinks needed.

Hi @Pskoog3,

Can you run uorb top? I'm looking for the publication rate of sensor_accel, sensor_gyro, etc. It sounds like the LSM9DS1 is not working right at all.

Can you describe everything that's on this board? For testing the closest thing I have is a Navio2.

@Pskoog3 please try master now that https://github.com/PX4/PX4-Autopilot/pull/17239 has merged.

@dagar still same issue... sensors seems to work fine and gets calibrated but still having the following error messages in console and Accel 0 fail: TIMEOUT! constantly coming up in QGroundControl!

ERROR [sensors] Accel #0 fail: TIMEOUT! ERROR [ekf2] 0 - vehicle_magnetometer lost, generation 23 -> 25

Thanks for the update. Can you grab a fresh log with current master to share? https://logs.px4.io/ Are you running px4 as root? Maybe capture a screenshot of top (or htop) while px4 is running to get a better idea what's happening both on the system and within px4.

I use htop to see the individual threads within px4.

@dagar here is the fresh log with recent master... https://logs.px4.io/plot_app?log=e423f38f-4090-4a16-bf73-d3aeab883f5e

yes, running as root... $ sudo ./bin/px4 -s px4_rpi.config

screenshot of top with px4 running...

screenshot of htop...

screenshot of console...

screenshot of QGroundControl messages...
