Don’t answer as in chat, you can edit your message to add some info.
From your pictures you placed vfd.conf in /flash, but it should be placed in /storage/.config
You could also find this directory via smb share
\IP_of_your_box\Configfiles
I have a box Qintex Q912. From Android dtb
hbs658 {
compatible = “amlogic, hbs658”;
dev_name = “hbs658”;
status = “okay”;
gpio-scl = <0x24 0x4c 0x0>;
gpio-sda = <0x24 0x4b 0x0>;
};
I tried this configuration https://github.com/arthur-liberman/vfd-configurations/blob/master/m9-pro-u2c-x-u5x-s-vfd.conf
Unfortunately it did not work. Could you help?
According to the DTB, m9-pro-u2c-x-u5x-s-vfd.conf should work for your box.
What didn’t work exactly? The display remained off or displayed garbage?
If it was completely off, reboot and run
dmesg | paste
and
systemctl status openvfd | paste
