Hello everyone,

I’ve been experiencing issues with the dump1090-fa service on my DietPi system for the past two weeks. The service tries to start but keeps failing repeatedly. Here are the relevant logs:

My DietPi version is 9.5.1 on raspberry pi 3

I have tested with two different FlightSticks, but the problem persists. Here are the test results:

Does anyone have suggestions on what might be causing this problem or further steps to diagnose it?

Thanks in advance!

Hi - not sure this will help, but I recently saw “cb transfer status: 5” errors when I was running a Pi5 with a Pi4 power supply and hit the Pi5’s power limit.

If you have another power supply, try swapping to that and see if the problem persists.

Thank you for your suggestion! I tried changing the power supply and it actually started working perfectly. The strange thing is that even after running dmesg | grep -i voltage, there were no voltage warnings or errors reported in the logs.
