Hii notFound, do you still have the vfd.conf file for Tanix tx5 plus. Can’t download the link you posted. I have try a few for tanix and none works.
Use the TX5 Max config and remember to install vfd from repo.
Works for me with TX Mini, Max and Plus.
Thank you so much for the reply. I have try all of the Tanix files and only 1 works for me was the tx5 pro.
It’s works well but it’s in 24 hour time. Just wondering is there support for 12 hour clock?

12 hour display is not supported right now.
Thank You, You guys are doing a wonderful jobs.
Hi Guys,
I’ve been trying to get OpenVFD working on a Z69 Pro 2GB just like @jimbo3146 did in his topic. Unfortunately just as he was unsuccessful I can’t get it to work either 
.
To make sure this device also contained the fd628 chip I opened the case, and discovered that it did indeed contain the fd628. I’ve checked the dtb → dts file and at the very last line it does mention fd628:
fd628_dev {
compatible = "amlogic, fd628_dev";
status = "okay";
clk_pin = <0x28 0x5f 0x00>;
dat_pin = <0x28 0x60 0x00>;
stb_pin = <0x28 0x61 0x00>;
};
But these pins do not seem to work. I did however notice that the dts file lists a different id than CoreELEC advises:
model = "Amlogic";
compatible = "amlogic, Gxbb";
amlogic-dt-id = "gxl_p281_2g";
I tried that one as well but to no avail. Unfortunately there are no debug kernel options enabled in Android So I cannot see which GPIO’s are assigned in /sys/kernel/debug/gpio so that’s no good either. Then I looked at a debug app which instructed me to place a empty file with the name .AMLCOPYLOGS on a external storage media after which it copied some logfiles to that medium. It did include a dmesg which I hoped would show some references of SPI or fd628 but it didn’t. Only some mention of FD628_Demo:

Which seems to be a process that makes use of /dev/fd628_dev:
CPU usage from 1224467ms to 322723ms ago (2015-01-01 00:30:25.759 to 2015-01-01 00:45:27.502):
6.5% 4058/FD628_Demo: 0.7% user + 5.8% kernel / faults: 6 minor
Decompiling that APK won’t help me much I suppose, since it interfaces with /dev/fd628_dev directly and does not use the GPIO’s.
So long story short, I would really like to get the display working since that’s the only physical sign that the device is turned on (without turning on the TV ofcourse 
) but I’m out of options 
Which version of CE are you using? And which DTB file?
Which SoC does your box use? You can see that in system information screen in CE itself.
Have you tried the vfd.conf file in the thread you’ve linked? Are you getting the same error as jimbo?
Also, what happens when you run cat /sys/kernel/debug/gpio in Terminal Emulator in Android?
Which version of CE are you using?
I’m running the lastest -ng release:
CoreELEC (official): 19.3-Matrix (Amlogic-ng.arm)
And which DTB file?
I’m currently using gxl_p212_2g like is advised on the Device Trees page:
Z69 S905X 2G gxl_p212_2g
Edit: Now I do however notice that the Z69 mentions the S905X, while my board seems to use the S905W.
But i’ve also tried gxl_p281_2g since it was mentioned in the decompiled android dtb file.
Still this made no difference.
Which SoC does your box use?
coreelec:~ # cat /proc/cpuinfo
model name : Amlogic S905W rev d
Hardware : Amlogic
Revision : 0400
Have you tried the vfd.conf file in the thread you’ve linked?
Yes, I did and same result no life on the display. 
Are you getting the same error as jimbo?

what happens when you run
cat /sys/kernel/debug/gpioin Terminal Emulator in Android?
I tried but my Android kernel does not seem to have debug compiled in, I’m not very familiar with android maybe this have to be turned-on somehow? Right now the entire path /sys/kernel/debug is non existent.
Can you post the android dtb file? I’d like to take a look and compare.
Yeah sure.
Side note: I’ve dumped them from within CoreELEC using dd if=/dev/dtb of=/tmp/dtb.img since I had no access to /dev/dtb from Android.
I would like to attach the files, but since I’m a new user I am unable to, can you enable this for me?
I’ve 3 files to attach:
- an original dump.
- a dump with corrected header, otherwise
dtcwas not able do decompile thedtbfile. - a decompiled dts file.
Edit:
I’ve uploaded a .zip file containing all 3 files to github: Z69_Pro_dts.zip
Ok, try this dtb in CE and the vfd.conf file from the other thread.

But the line mentioning the WiFi GPIO is indeed gone, but now something is claiming the dat_pin?.
Does the box have bluetooth?
No, not that I know of at least.
I’ve opened the box to have a look at the LCD screen (which had a fd628) and only saw one chip that had an antenna attached SV6051P that to me seems like a WiFI only chip.
Ok, I removed the bt entry in the DTB, which seems to hog the dat pin.
Let’s see if this makes any difference.

GREAT! making progress here.
The screen turns on but some of the characters are incorrectly displayed:
The character with the arrow blinks and the time should be 17:10 instead of 17:11, also there is no USB attached at the moment neither am I playing a movie so pause and play shouldn’t be on?
Thanks, that did the trick!
Great work! 
Some questions still remain:
- Is there any use for the clock symbol? I noticed that it is now turned off. Not that I do mind but just wondering.
- It seems that the
gxl_p212_2g.dtbfile is not entirely compatible with the z69 2GB, should an alternative be made? - Should we add the vfd config to here?
- The issue was the order of the characters.
The clock icon is not used in CE, but you can use it for other things. I used it as the storage access indicator. - Right, the DTB will need to be adjusted. It’s possible to do that using an autostart.sh script.
- I will once it’s finalized.
Edit: Can you verify that wifi still works? That we didn’t break anything in the functionality with the dtb changes.
but you can use it for other things. I used it as the storage access indicator.
Ah I see, was hoping to use it as a network activity indicator as I do not use local attached storage, but seems the plugin does not (yet) support this.
It’s possible to do that using an autostart.sh script.
But without documentation users probably won’t find that?
Can you verify that wifi still works?
Sure, personally I do not WiFI.
But the adapter is found and is able to see some SSID’s in CoreELEC:
wlan0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
At first I thought WiFI was removed since the dtb file specifically had nowifi it its name
