You are still using old dtb with GPIOZ_5 issue.
[ 86.438227@3] c9410000.ethernet is using the pin GPIOZ_5 as pinmux

Copy gxbb_p200_1G_sen5.dtb (39.9 KB) to SD card and rename it to dtb.img.

This is strange. In initial communications demod is answering on addr 0xc. You can see in log:

There is a issue with tuner. Most likely there isn’t Airoha AV210x tuner. I can’t support dvb tuner without knowing chipset used for it.

did u mean this

The DVB board looks very similar to Wetek Play 2xDVB-S2 tuner board with Eardatek tuners.


But WP uses Eardatek EDS-11030FNPVA EDS-11030FNPA.pdf.
In your box is EDS-11270NPVA currently End-Of-Sale, as Eardatek offers following tuners:
http://ww.eardatek.com/HalfNIMTuner1.shtml.
You can only open tuner box to see chip used for tuner.
DVB-S2_AV2012_Tuner

It is the EDS-11270FNPVA tuner with airoha av2026

Airoha AV2026

Airoha AV2012

There is minor difference in pin4 (RFN-) and the name of pin 13 (TEST=>PD).

Here Airoha AV2026 document.

hi, i have an amiko a4k v5.1.1 and i have tried all the dtb. img and there are no dvd adaptrs, and i really want to use coreelec. thanks for all team coreelec.
greeting

With dvd you mean dvb? Did you try the various DVB drivers under Add-ons -> CoreELEC Module Drivers?

yes sir, I tried all three

As I’m not a dev and I can’t really help you but in general it would be good to post some logs. Just a guess but dmesg and lsusb logs might be useful with the dtb you think is the most correct one.

As you’ve already posted this same question 11d ago in the Amiko A4 thread I would recommend continuing over there instead of taking over this thread as well.

What backend are you using?

Do the dvb adapters show up in that?

Is it a combo box (DVB-T & DVB-S) you have?
