I’ll try to explain better.
If the mailing-list references the HCL: Rock Pi 5 page then that leads to a dead end.
The link on that page leads to https://rockpi.org/ where the Rock Pi 5 product can’t be found.
The Radxa site is now actually located at http://radxa.com/
The Radxa site has a products page but there’s no product called Rock Pi 5
The specifications on the HCL page instead hint at the Rock 5A.
But there’s also a SBC called Rock 5B which is the one I have.
…and the new Rock 5C that soon will be followed by the cut-corner Rock 5C Lite.
Later this year Radxa will add a mini-ITX motherboard too, the Rock 5 ITX.
They’re all different and need separate HCL pages.
On top of that I don’t know enough to formulate what I am searching for. Yes, the input voltage is what I want to know, but how does the computer measure it and what process makes that measurement available? The suggestions I get from the Radxa Forum (from their Debian viewpoint) fail because the path to the information that I want doesn’t exist on my machine running Tumbleweed.
The latest comments from the Radxa Forum points at ACPI being the reason to why that folder inside of /sys doesn’t exist here. So I carry on, regrettably irritating people in the process, but slooowly getting there. …I hope.
And it all started with an innocent quest for the input voltage of the USB-c socket. Little did I know…
