Hi @TheCoolest, I have bought this box:
CoreELEC:~ # udevadm info /sys/bus/sdio/devices/* | paste
http://ix.io/4F0k 1
CoreELEC:~ # dmesg | paste
http://ix.io/4F0l
when I enter cat /sys/kernel/debug/gpio in the Android terminal
indicates that it is inaccessible. Is there anything else I can do to provide you with useful information?
I’m not sure what box you got.
But if there’s no access to GPIO, then the only thing you can do is try to extract the DTB.
It may contain the display config.
The device has Android 11 and I see that I have root access. Is there a route where you can find what you need? I am providing you with the following information in case it is helpful:
/sys/kernel/tracing/events/gpio/gpio_direction/format
name: gpio_direction
ID: 949
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:unsigned gpio; offset:8; size:4; signed:0;
field:int in; offset:12; size:4; signed:1;
field:int err; offset:16; size:4; signed:1;
print fmt: “%u %3s (%d)”, REC->gpio, REC->in ? “in” : “out”, REC->err
/sys/kernel/tracing/events/gpio/gpio_value
name: gpio_value
ID: 950
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:unsigned gpio; offset:8; size:4; signed:0;
field:int get; offset:12; size:4; signed:1;
field:int value; offset:16; size:4; signed:1;
print fmt: “%u %3s %d”, REC->gpio, REC->get ? “get” : “set”, REC->value
I don’t think this helps. I need to see which pins are mapped to the display controller.
Is there a file in which I can search for that information? How could I extract the dtb? I have the ability to run commands, if it helps.
Sadly looks like this trick doesn’t work either. I’m not really sure what else to suggest.
If anything else occurs to you, just let me know. Maybe some command to enter in the Android terminal?
Maybe, having root access on Android there is something that can be done.
I attached an image of the panel numbering, in case it helps.
Does not make sense with root to not get output from Terminal Emulator.
Try a different version, s of Emulator
In settings go to app and allow permissions, etc
Something…
If you have not allready tried these.

Maybe will help
Happy Testing
With the help of @YadaYada I got the content of the DTBs, the extraction worked, I was just doing something else wrong that didn’t let me get to the data I needed.
Try this vfd and see if you get anything on the screen.
t95w2-vfd.conf (1.3 KB)
If it doesn’t work, try this vfd:
https://raw.githubusercontent.com/arthur-liberman/vfd-configurations/beea98634cf9a4c7f70f6b565158ff7140c357f6/tanix-w2-vfd.conf
The panel now works (first option). For some reason it does not correctly display the time (10:21), date (03/09) and temperature (43 degrees), as can be seen in the images. Another issue, the time is only shown at the beginning, then only temperature and time alternate.
Try this:
t95w2-vfd.conf (1.3 KB)
Also, when the time is displayed, do you see the colon blink? Or is it always off?
Regarding alternating time and temp, that depends on your settings in the OpenVFD addon.
Now it displays fine, but even though I have colon blink activated, they do not appear. The time is still not displayed beyond the start, although everything is configured correctly in Openvfd, I think.
Try to reduce the “Display for” of the temperature, or disable them completely.
It’s some sort of configuration issue with the timings you have set.
Does any other icon blink? Instead of the colon? Is the ethernet icon always on or does it blink?
Do any of the other relevant icons blink/work?
In your pics, it’s hard to make out, but looks like the VFD chip is a 650, not 655, correct? (the small 16 pin chip at the top of your picture)
the ethernet icon blink at startup, while the time is displayed.
Change the first numer (2) in vfd_chars='2,1,2,3,4' to 1 or 3 or 4.
One of these should make the colon blink. The other numbers will make the other icons blink.
Can you please map numbers to icons? For testing, disable the OpenVFD addon in kodi, this will keep the clock + blinking icon.
1 - ?
2 - Eth
3 - ?
4 - ?
I lowered the temperature display for 15 seconds and the time is now showing well.
Clock colon is now solved, but is there a possibility that eth or wifi will be displayed depending on the type of connection being used?
1 = Wifi
2 = Eth
3 = Clock colon
4 = USB
I think this should fix the icons too
t95w2-vfd.conf (1.4 KB)
It should only show Eth when you’re connected with a cable.
Wifi should show when wifi is connected and USB when a USB drive is plugged in.
It does not work. The only thing that has happened is that Clock Colon has disappeared.
