I've got an original Tinker Board rev 1.2 that I want to install Klipper on for a 3d printer. I've tried installing both Armbian 24.11.1 Bookworm Minimal / IOT and Armbian 24.11.1 Noble XFCE and with either one when I try to shut it down with "sudo shutdown now" or using the shutdown option in the desktop mode, the board seems to shut down, the lights go out but it still draws around 700mA and the CPU stays warm or even gets a little hotter (with the board powered on but doing nothing it draws around 460mA).

I've tried disabling wake-on-lan but that didn't help.

I've tried adding power_off to the extraargs line in /boot/armbianEnv.txt also didn't help.

It doesn't make a difference if it's powered by the micro usb port or GPIO.

 

I've tried installing Tinker Board S R2.0 Debian 10 V3.0.11 from the Asus website and that does shut it down ok but it's old.

 

I don't really know what I'm doing, I'm only able to do what I have with help from Copilot.

 

Anyone have any suggestions how to fix this or what I should do?

 

Thanks.

I see it is from 2021. So a typical case where the board vendor has left its customer. Still Debian10 where in half a year we will have Debian13 already. I also see there is an older version Debian9. So ASUS sold the boards, supplied it with some OS image, did 1 time an update, but that's it. It looks to me that they never made any profit from this SingleBoardComputers business, so not surprising that support ended, that is the hard truth. It is a pity as I remember when it was put on the market, I found it a promising alternative to RaspberryPi and I have several ASUS PC motherboards that already work for 10+ years. But of course people still pay Microsoft.

 

This is more or less the base for expectation level what you can do with the board. You can make some mix of the old ASUS Debian10 image and a newly build more generic Armbian image, but that requires quite some Linux know-how and low-level tools to do. Otherwise, pull the powerplug after shutdown.
