The X92 vfd should work.

If it doesn't post the Android DTB and I'll take a look.

I extracted the DTB from the TX9 Pro firmware. You should use the Vorke Z6 vfd conf file.

Ok. I'll see if I can extract the DTB out of the TX9 pro firmware.

RayW

Sadly that didn't work right, the output didn't contain the DTB.

You may have to follow Sholander 's suggestion.

This is *ELEC basics, LE creates a few shared folders, one of them is `downloads` and it's normally stored in /storage, together with a lot of other folders.

Linux is case sensitive, so make sure you don't use caps when you type in commands.

Try to run these commands and post the URL you get in return.

cd /storage
ls | paste

To extract the DTB, you have to run the command when you are in LE.

A T95m works great, it should also have a better processor, S905X.

Because it's probably a better idea to try it for yourself and see if it works well for your needs, than to wait for someone to "kindly" give you an answer whether it works or not.

It's also very likely to take a lot less time than to wait for someone to reply.

And in addition, LibreELEC 8.0.2 is ancient, and you should install something newer.

We should probably take this to PM, as there's no point in cluttering the forum with our dialogue

vvd214 Odd.

I suggest you disable the Kodi openvfd service for testing purposes.

SSH into the box, kill the OpenVFDService process.
Then start it again like so:

OpenVFDService -dm &

This will run the service in demo mode, and should look something like this:

If you could take a video of what happens on screen, it would be great.

vvd214

OK try it with the attached dtb. Put on root of SD card and rename to 'dtb.img', like usual.

vvd214

OK, now there's some progress.

Looks like there is now a conflict with pins allocation. I'll look into it later today if I have time or tomorrow.

This will probably require a dedicated DTB for this box.

vvd214 What does

cat /storage/.config/vfd.conf | paste

produce? It's highly unlikely that it's trying to read the vfd.conf from somewhere else.

The Kodi service can't affect the dmesg output from openvfd module, what you see there is what is read from vfd.conf. And currently what I'm seeing is that you're using the vfd.conf file narcotic posted.

From dmesg:

You're not using the vfd I attached in this post...

LED (VFD) Displays in LibreELEC

Make sure that you put it into Configfiles folder, and rename it to 'vfd.conf'

vvd214 You need to reboot the box after replacing the vfd.conf file. From the log it looks like you're still using the previous vfd.conf.

@The Coolest

I re-install Coreelec 8.95 (with dtb: gxl_p212_2g.dtb) and OpenVFD services, but sill black display

Here is my Android _DTB

dmesg - http://ix.io/1jmg

systemctl status openvfd - http://ix.io/1jmj

Please, have a look. Thanks

Thanks. Try the attached vfd.conf.

I don't know what version of the vfd driver wrxtasy uses in 8.2.4.2, but in 8.2.4.1 he wasn't using the driver I adapted, so it won't work at all without a per-box DTB configuration.

Also, the dtb file you posted is empty, you may have to extract it from Android directly.

Try running the following commands and post the URLs.

dmesg | paste
systemctl status openvfd | paste
(if the above didn't work try this)
systemctl status fd628 | paste

Have a look at the LE openVFD Addon configurations. There is all sorts of stuff to adjust.

I think he's saying that the display is stuck at "boot", which normally means the vfd driver has not been started or the wrong vfd.conf was used.

RayW

Try the DTB linked in this post: LED (VFD) Displays in LibreELEC

I think the TX3 vfd may work, if it doesn't, I'll need the android DTB to look for the vfd configuration.
