X96 mini Power Off not working

TmR · 2 December 2020 14:01

Hi, i cant power off my x96 mini (s905w/2Gb).

Tested on CoreELEC-Amlogic-ng.arm-9.2-nightly_20201129-Generic.img
with gxl_p281_2g.dtb

The screen turns black and the status LED stays blue but the box restarts after around 3 minutes.
Tested with shutdown from Kodi and shutdown now -h from ssh.

Any Ideas?

Hi, thanks for the Answer.

I’ve run the BL301.BIN Injection but the Problem is still the same.
Also with shutdown now -P the box still goes to black screen with blue light on for 3min and then reboots.

Output of the Injection:

X96mini:~ # inject_bl301
Starting bootloader blob BL301 injection tool…

This tool can be used to update the bootloader
blob BL301 of the vendor bootloader on the internal
eMMC. This bootloader blob BL301 is customized by
Team CoreELEC to support all wake-up features like
CEC, Wake-On-LAN, IR, and GPIO wake-up from
suspend or power off state!

Please confirm to write the bootloader blob BL301 to
the internal eMMC! Please ensure to update first the device
to the last vendor firmware! And remember if the vendor
firmware get updated you have to do this step again as the
bootloader blob will be overwritten!

Continue? [y/n] y

Warning! GXL support is still experimental!
It is possible that the injection brick your device and it will not boot anymore !
It will be needed to short out the eMMC to recover the Amlogic device.
So there is no warranty by team CoreELEC if the injection will be successful or not!
Please confirm again to write the bootloader blob BL301 to
the internal eMMC on your GXL device!

Continue? [y/n] y

Update of ToC header on eMMC is not needed

Finished update of BL3* blobs on internal eMMC!
Please reboot device now and enjoy the new CoreELEC wake-up features!

You can try systemctl poweroff.
If it still wake up an UART log is needed what the reason is.

Hi, i have exactly the same problem…
HW: X96 mini 2GB/16GB, purchased two days ago from amazon.de.
Older images (including stable ones) do not work, installed:
CoreELEC-Amlogic-ng.arm-9.2-nightly_20201129-Generic.img.gz / gxl_p281_2g.dtb as dtb.img
Remote is working now, using meson-ir and a modified alfawise_h96pp keymap from the repository.
Started inject_bl301, roughly the same output as above. Power off -> it goes into a kind of sleep mode (my monitor stays on: black screen but backlight is still on) and the box restarts after a while, same behaviour through remote, shutdown menu or “systemctl poweroff”.
I was trying gxl_p212_2g.dtb and gxl_p281_2g.dtb too, i saw no differencies between th two. Originally, under android:
cat /proc/device_tree/amlogic-dt-id shows:
gxl_p212_2g but the CoreElec downloadhelper states it should be gxl_p281_2g.dtb so i kept this one.
Any other hint i could try to get to a working “power off”?
Thanks

This behavior is caused by the auto_wakeup function in the new kernel and has to be analyzed carefully (probably timeout is written in the wrong address area…). For a temporary solution, try deactivating auto_wakeup in bl301

TmR · 7 December 2020 12:45

Hi, i’ve disabled the CEC-Wake-Up in the Coreelec GUI but the Problem is still the same.

@wallabie i’ve also installed Coreelec to internal and the box runs fine but still with the shutdown Problem.

Portisch · 7 December 2020 14:18

Wait until the box resumed, open SSH connection and please post the output of:

dmesg | grep rtc

wallabie · 7 December 2020 16:28

after self-restart:
CoreELEC:~ # dmesg |grep rtc

Hi, i see you are using p281_2g dtb, have you tried the p212_2g too?
Under the original android is the p212_2g installed…

wallabie · 7 December 2020 16:37

How can i deactivate auto_wakeup in bl301 please?

TmR · 7 December 2020 17:23

212_2g boots only on white usb-port and 281_2g on black usb-Port
But with both shutdown isn’t working

U can deactivate the auto_wakeup in The Kodi/Coreelec Settings in the CoreELEC-> Hardware

Portisch · 7 December 2020 17:48

The problem is the wake up reason is unkown.
Use first last nightly and disable CEC wakeup in ce settings at all.
Disable also WOL and try again.

With a UART log I can tell u the reason for the wakeup.

wallabie · 7 December 2020 19:54

How can i make an uart log? Do i need some special hardware?
I dont know if that helps, but i tried “shutdown --reboot” , the box stays in that “zombie” status (black screen but the tv shows “1080P input signal”) and the box does not restart.

wallabie · 7 December 2020 19:57

I used the same microSD slot for for both. Does anyone know wich is the right one for this box? (gxl_p281_2g.dtb or gxl_p212_2g.dtb) What are the differences?

TmR · 7 December 2020 20:35

in the Android Recovery Menu (long press reset without usb) mine shows p281 7.1.2/NHG4L/root.

i’ve flashed an old android image (20180512) with the usb burning tool but still get the same shutdown problem.

The NG Version of 9.2.5 stable works fine for me too btw but still the shutdown problem

bumerc · 8 December 2020 08:31

Just comment out lines 231-239 and compile the u-boot. However, you also have to patch the u-boot for 2g RAM support and faulty reset button function on p281 boards.

Or ask @Portisch if he could test compile bl301 without auto_wakeup

Portisch · 8 December 2020 09:40

Some other user use this timer on GXL platform I guess.
On G12* platform it’s replaced by a RTC wakeup. I currently searching a bug about RTC wakeup after 1-5min for CE 10.0. When I found this maybe the timer issue can be solved to.

Portisch · 10 December 2020 09:38

First question: why buying a device with a obsolete SoC? No answer needed…

Second:
Here is a image where I deactivated the auto_wakeup in bl301 blob for p241/p281 only. So please boot with your current image and be sure bl301 is injected. Send the device to suspend - and it wake up?

If yes please update with this tar and try suspend again after update. The bl301 blob is automatic updated if it was injected before.

wallabie · 12 December 2020 08:46

Thanks a lot, i will try the image later today.
To your second-not-to-be-answered question: beleive me, it was not an intention to buy one like this. I went trough all the hardware infos here, unfortunately all listed devices are older and not on the market anymore - you can get them eventually over ebay. I am happy enough to got one with S905W, as i read now there are some out with an other SoC than stated. The other thing is the naming of the boxes, there is no direct correlation between names and hardware… A broader hardware database would be helpful, until then: do not by an X96 mini like mine… Thanks
