so the problem 1. is due to that this is not AVL6862 but AVL6261 which creates problem 3 for You which is that the current AVL6862 addon does not have driver for that. There were some attempts to include this driver but with no success and I do not have any device with this demod so I will not help with that.

rozpruwacz · 21 May 2026 13:13

although @taki reports that something “worked” in this message:

when I find time I look into that.

rozpruwacz · 21 May 2026 15:48

I need clear photo of marked crystal resonator. I need to know the number printend on it.

Mike · 22 May 2026 09:41

hi again rozpruwacz i still appreciate your help with my stb
a friend of mine has gtmedia combo and your gtmedia branch worked fine but he want to use coreelec 21
the problem now with vfd and t2 tuner
i modified your driver m88tc6800 with cxd2878 you provided in wrapper but still no luck and not getting any snr

so do you have any branch for gtmedia combo coreelec21?

rozpruwacz · 22 May 2026 09:57

no and I do not plan to make it. on CE 22 everything is working fine so I see no point.

Mike · 22 May 2026 09:59

okay thanks

Hello brother

I have a device Gt combo and I used your source code and the distribution works fine.

But Bluetooth and wifi is working after loading them manually

They never autoload by default

How to solve that

Also after loading Bluetooth manually using autostart.sh the Bluetooth remote never showed up in Bluetooth devices even when using the buttons for pairng

rozpruwacz · 23 May 2026 14:42

I’m not using bt or wifi so I was not aware of that, i’ll look into that.
regarding remote over bluetooth. actually I had also the same problem at first time. Then I succesfully connected the remote to other tv box and then I tried again with gtcombo and it worked … So, maybe try the same. maybe this remote remembers that it was connected with the same hardware and does not show up until paired with other device.

rozpruwacz · 23 May 2026 18:05

I checked my gtcombo and it loads wifi/bt driver automatically.

check if You have the same output of those commands:

gtcombo:~ # cat /proc/device-tree/sdio\@ffe03000/wifi\@1/compatible

I don’t have it These are the results of the same commands you entered.

You have wrong dtb, use sm1_s905x3_gtcombo.dtb from my branch which adds this node:

&sd_emmc_a {
	brcmf: wifi@1 {
		compatible = "sprd,unisoc-wifi";
	};
};

MunirGh · 23 May 2026 19:49

I already used dtb for gtcombo compiled in build
Can you send me yours to try?

rozpruwacz · 23 May 2026 19:52

dtb.img (77.8 KB)

dnmnhat · 24 May 2026 10:00

If the CE 22 on Gtcombo is working well, can you push the project to the main branch?

To be honest, I have no experience in building images for that device

MunirGh · 24 May 2026 15:12

I was a user DTB The allocated file, but I told you I wanted a file to test it as well, to confirm.
The same problem persisted: Wi-Fi and Bluetooth were not working automatically.
like that Service Oscam The same applies to cases where it doesn’t work automatically except through Autostart .
And thanks
