While videoplaying from network via SMB (AVC, opus) my HK1 Rockbox 4 randomly freezes.
I tried alot to solve the problem (tried USB-LAN adapter, Coreelec 19.5 Matrix, 20 Nexus new era, new generation, various dtb) but still same behaviour.
There are still 2 possibilities I see:
Powersupply and Heat.
One thing i cannot verify is temperature/overheating as the device has to visually disappear in a box (wife dont want to see it).
I opened the device and saw a tiny heatsink on the mainchip and i am willed to exchange it to a bigger one, but it seems its glued so i do not want to risk to break the pcb or chips.
Another thing I noted that at least in the last new era 20 the cpu governor is “performance”. Is there a way to let the cpu cooldown during idle or low cpuload?
currently the device is powered by an custom cable from TVs USB3 - Port to the device. I assume the USBport provides enough energy and the cables I used are thick enough. But how can I be certain about that? I cant find the original powersupply anymore.
So reducing powerconsumption by changing the cpu-governor should show improvements on both remaining frontlines (heat and powersupply).
But how can I supposingly do that?
