Odroid C5: Ethernet is flashing constantly

    Hello ,


    have bought this SBC some month ago,

    and seem function quite well ,


    took it out of the case and noticed that the light of Ethernet is flashing every second or so, or pulsing,

    but the Libre/CoreElec is just sitting there, i am not interacting with the device / device is on, but not actively used by user.


    my quesiton><

    is this a fault of the SBC itself that it is doing so much activity over Ethernet, or is it a shortcoming of LibreElec/Coreelec that it is sending signals all the time, even when it is not used?


    thanks.

    I can't comment on the C5 (no idea what that should be) but it's more likely that's standard network traffic in your LAN, coming from other devices (or your router) that reaches your device.

    Lots of network protocols (ARP/ND, MDNS, ...) rely on small broadcast or multicast messages that are transmitted to all devices in a LAN segment - and those cause the network LEDs to blink.

    You'll see the same blinking on PCs, switches etc, too - if they have LEDs.

    so long,

    LE has no support for the Odroid C5 board so you must be running an Armbian or CE image; thus you are in the wrong forum. We have no interest in and do not support the codebase you are using.

    yeh, thanks, it is CoreElec, but i have just registered and seem not be able to post new topics over there (another feature not well understood)

    yes, it is LED flashing all the time, and it is distracting-disturbing, but helps to see that there is excactly an issue with the software or hardware, not sure where this should lead to.

    the SBC probaly consume less power, so no one bothers to make a "sleep" function available for the ethernet if not used, unless , of course, this is afeature of the software as it is trying to capture data from elsewhere.

    if it is not being used, it shoudl stay silent as much as possible, that would be ideal.
