Hudiy Crash Troubleshooting

[proteinklumpen]

Hey,

I don't know why yet, but I witnessed 3-4 crashes of hudiy / the whole pi. It happened a few seconds after connecting my smartphone and after the android auto emulation started. For 10-15 seconds everything worked fine, then hudiy crashed and the whole raspberry pi desktop was bugged. No background, no usable mouse, some error icons in the taskbar. I wasn't able to connect via ssh at that moment. Even pressing the pwr_button of the raspberry pi itself threw errors. After rebooting, everything worked fine. I could do this 4-5 times in a row and always a crash.

I wanted to find out whats happening. Now the crash doesn't occur anymore, I didn't change anything. Now its just in my lab environment, but I don't want this to happen in my car. Can somebody tell me where to look for hints? I enabled journalctl Storage=persistent

Does hudiy have its own log? Has somebody had similar issues?

Are you connecting wirelessly or via USB? It might be a power issue similar to the one from this topic: viewtopic.php?p=195#p195

Hey,

I am using USB. And yes my error looks exactly the same, buggy desktop with a bunch of warning and error icons in the taskbar. I am already using a usb-hub with external powersupply. The raspberry pi is powered by a 12-5V DC Converter, capable of over 100watts. Do you have any tipps on what else to do?

Can I somehow confirm that its an electrical problem?

The Raspberry Pi is very sensitive to voltage drops. Even minimal fluctuations can cause various problems, such as USB ports disconnecting, throttling, or even a reset. You need to check how your power supply's voltage behaves under load.

We usually use this power supply in our setups https://www.dfrobot.com/product-752.html
