Maybe you can send it upstream?
I guess we should bring the board itself upstream first? Or do you mean upstream libreelec?
What do you do after shutdown? After shutdown you can only power cycle the board to turn it on again. You can of course try with removing "quiet". I suggest you add "ignore_loglevel" to get even more output.
I just do a shutdown in kodi and then disconnect the board from power supply. Then i reconnect it again. I still have to do some investigations, because on the HDMI input of my Samsung TV i get the black screen - but today i tried the same Box on a simple HDMI monitor and get Kodi screen again.
[EDIT]Update: After 3 hard power disconnects, the box goes to black screen even with the monitor. This smells like some random issue... I'll try it later agein. It's strange anyway.... [/EDIT]
[EDIT2]After disconnecting the board from power for ~10min, it boots again into kodi... Maybe this is a 2GB/3GB mem issue or thermal issue after all?
Btw, this happens with GitHub - rellla/LibreELEC.tv at eachlink_working, which is simply the Tanix Image with kernel parameter fix and the remote added...
With the other branches, i don't get networking up. But therefore I have to look into the dts for the differences.
By device you mean board? Devices in Allwinner project are actually SoCs. There is no way to set board specific kernel options. However, you can make SoC specific options. Just move that line in options file in appropriate device subfolder.
Yes, board. Thanks for your answer. So best would be to find a way, how this could be fixed within the driver?
