doesnt work systemctl status openvfd
Post dmesg please
Try to run this, make sure there are no errors.
After that reboot and see if the display turns on.
mount -o rw,remount /flash
fdtput -t s /flash/dtb.img /soc/apb4@fe000000/i2c@6e000 status disabled
sync
yay !!! it works you beautiful person , thank you so much 
I also have a box for s905w2 and applied vfd.conf as for @seias but the display is still blank.
My dmesg: http://ix.io/4mOn
I logged into android:
$ adb shell
oppen:/ $ su
oppen:/ #
oppen:/ # cat /sys/kernel/debug/gpio
cat: /sys/kernel/debug/gpio: No such file or directory
1|oppen:/ #
Can anything else be done?
Uninstall Arthur Liberman OpenVFD
Reinstall
Change something in OpenVFD Configure
Parameter
Then Reboot to apply changes
From log ramoops error - 12
From log looks like it loads
12.406922 load module: openvfd
OpenVFDVer: V1.4.1…
Version on my boxes is OpenVFD Version 1.0.4.0
Maybe reads different in log
How is Progress?
You have the same TV Box as @ seias?
Or just CPU is common?
Common CPU has nothing to do with OpenVFD
Try latest Version Terminal Emulator App/APK
In Android for debug gpio data
Happy Testing
Unfortunately without success.
No, it’s not the same box as the @seias , only the same CPU.
The dtb (dts) files look very similar, unfortunately the display does not work,
although dmesg shows no errors: http://ix.io/4n0z
My box is android 11 and from what I’ve read it doesn’t have compiled debugfs support.
I access the box via adb shell and su. Unfortunately without debugfs I can’t find the correct gpios
I have no ideas what to do next.
Without the ability to get the gpio dump, I’ll need the DTB file from Android.
If you already have the decompiled DTS, please post it.
Thanks for your help, I am attaching the android dts file from my box:
s905w2_2g.dts (86.5 KB)
By the way, dmesg, from the new night build update: http://ix.io/4n6N
What box do you have?
Cheap Chinese, sold as LTC BOX042.
Under android aida64 shows that it is Droidlogic.
Try this
ltc-box42-vfd.conf (1.2 KB)
Thanks a lot! It’s better, there’s something on the display.
In the fourth position, the upper left segment flashes ( possibly upper right ).
It was around 5:32 pm
Try this one:
ltc-box42-vfd.conf (1.2 KB)
Bingo, it’s okay.
Just out of curiosity, is all this display can display? I’m asking because there are other icons there (e.g. wifi indicator).
Thank you very much for help!! 
Ah, I tried to look the box up on google, and it showed just the 4 numbers.
Try this file, hopefully it’ll work.
ltc-box42-vfd.conf (1.2 KB)
If it doesn’t work quite right try changing vfd_display_type='0x01,0x00,0x00,0x06' to vfd_display_type='0x01,0x00,0x00,0x05'.
Now it is that the wifi display is blinking, changing from 0x06 to 0x05 does not change anything.
Go to the OpenVFD addon settings, go to Advanced settings, enable it.
Display type should be 1, controller type 6, common anode - off.
Go down to Index 4, and each time change the value, go from 0 to 6, and record which icon starts blinking for each number. Once we have this list, I’ll be able to create the correct config file.
