Telemetry lost (Ethernet) (Mavlink dies) when requesting log list from QGC

PX4 Autopilot
1

Hello,

Setup

  • PX4 V1.14.3
  • Board: Holybro - Pixhawk 6X

Issue

When using Mavlink (it’s running as MAV_1 instance), with all the recommended settings for the Ethernet setup, I’ve encountered that the associated Mavlink task dies/freezes when requesting the log list from QGC.

Sometimes it also happens when the drone disarms and the log file gets closed.

The SD holds about 1 GB of logs.

Once it fails when disarming or when requesting logs via QGC, the mavlink_if1 and mavlink_rcv_if1 instances are stuck at 0% CPU and the board needs to be rebooted.

  • Any testing ideas?
  • Is it a bug in the codebase?
