There is no power button on the board. When shutdown is triggered, the default action of the board is to reboot. To avoid rebooting, run shutdown -H now
which will halt the machine.
With Ubuntu 22.04, it appears that âshutdown -H nowâ still reboots?
Thereâs a watchdog that causes the system to reboot after halting. You can disable it via echo 'V' | sudo tee /dev/watchdog
before halting.
Seems like on Raspbian, the âStart Menu â Logout â Shutdownâ should do that for you. Otherwise itâs the same as Reboot.
We have already removed the watchdog so a standard sudo shutdown -H now
will be sufficient in the images download since last month.
With my Raspbian image, 2022-09-22-raspbian-bullseye-arm64+aml-s905x-cc.img.xz, sudo shutdown -H
does in fact shut down the system and it stays powered off.
Using the GUI Shutdown reboots the system. Minor point, but it was surprising the first time it happened.
How do I restart the device after shutdown? Just unplug and plug back in?
Yes. The boards consume 1W anyway so thereâs not much point to shutdown.
Is it possible to disable the watchdog on images downloaded prior? Rather than having to âecho âVâ | sudo tee /dev/watchdogâ every time I want to shut down the system?
We have disabled the watchdog by default for images since November. If you had an image from before, simply use the libretech-flash-tool to re-flash the bootloader.
Does the watchdog workaround work also for Batocera or Lakka? It is impossible to shutdown the board, it is constantly rebooting, thanks!
F.
For images not from our distro server, the watchdog stuff does not apply. You just need to halt instead of shutdown.
Any idea on how install halt on Batocera and Lakka?
Thanks
EDIT
Never mind on Batocera is already installed, simply it is impossible shutdown the board, I can only unplug the AC when exclusively the red light is onâŚ
I wonder if I can get some help, at least as customer, thanksâŚ
