@YUUJI-INOUE said in Persistent PX4 Sensor/Accel Failure on Stinger (D0013) with SDK 1.6.2 + Dev IMU/OV Servers:
Updated Support Request: Parameter Fix Attempt & Remaining Accelerometer/Position Mode IssuesFollowing the advice to update parameters, we have made progress but still cannot enter Position Mode due to persistent sensor checks failures.
Actions Taken Parameter Reset & Load: Executed voxl-configure-px4-params --wizard and selected D0013 (Stinger). Confirmed that /data/px4/param/parameters is now created and populated. Battery Configuration Fix: Manually corrected BAT_N_CELLS to 4 (was defaulting to 6) and BAT_LOW_VOLT to 14.0V. This successfully resolved the "Low Voltage" warning in QGC. Re-Calibration: Performed fresh Accelerometer, Level Horizon, and Compass calibrations in QGC. Performed Camera calibration. Current Status Manual Mode: OK. We can Arm the drone and spin motors in Manual Mode. We have also performed a successful test flight in Manual Mode. VIO: OK. The virtual drone in Web Portal follows the real drone perfectly. Position Mode: FAILED. QGC shows "Ready for flight" briefly after reboot, but rejects Arming (Command denied). After disarming from a Manual Mode test, Position Mode switches to "Not Ready". Web Portal System Check: FAILED. voxl-px4 still reports sensor_accel: result false. Values (e.g., z: 9.70) seem correct, but the check fails. Persistent Logs Errors (New Logs Attached)Despite the parameter fix, voxl-px4.log still shows communication timeouts with the sensors:
ERROR [muorb] [sensors] Accel #0 fail: TIMEOUT! ERROR [qshell] Command failed ERROR [muorb] [drivers__device] i2c probe failed Questions Since we can Arm in Manual Mode (suggesting the IMU hardware is working) and have loaded the correct D0013 parameters, why does voxl-px4 still report sensor_accel: result false with timeouts? Is there a specific driver or timing parameter in SDK 1.6.2 (with the dev branch IMU server) that causes these spurious timeouts on the Stinger? What is preventing Position Mode Arming even when VIO is healthy and Manual Arming works?We have attached the latest logs (voxl-px4.log, voxl-vision-hub.log) from this new configuration state.

I've been hooked on this for two weeks now. Can someone tell me how to set up STINGER VER1 from scratch?
