Downloading Log files causes Mag Errors #12007

Open tops4u opened 5 years ago

tops4u commented 5 years ago

Describe the bug While downloading Logfiles (> 10MB) the Cube started flashing Pink. Now by redoing it I noticed that the Cubes RGB LED "Breathing" is "stuttering" while Log Downloads. Sometimes it would timeout the Mags:

I do not think this is Mission-Critial, but still worth noting.

Drone (please complete the following information): CUAV Pixhack v5, PX4 1.9 RC2

Mag timeouts are usually an indication of the system being stalled, and not actually a problem of the mag itself. This would mean something in MAVLink FTP is consuming too much CPU or IO and impacting the system overall.

We run into this annoying issue quite often. is there a strategy that could solve it?

There are a few different cases, but some of them will go away after https://github.com/PX4/Firmware/pull/11571 is merged. Other things running in hpwork (land detector, shutdown logic, etc) will no longer be able to block mag readings.

I probably have to retest this, but I AFAIR it still happens in 1.9.x

@tops4u Could you check again if this still happens now? Although it is super old issue 😆
