If you look at the txt, some TPs give that error.

So there are errors only for some frequencies. but stil for other there is no signal lock. The tuner is not tuning correctly or the demod is not receiving the signal corectly.
I don’t have an idea what can be wrong other that the driver code itself. There is almost no configuration variables other than i2c settings which are correct since there is no i2c errors and oscillator frequency which I can get from Your pictures (27MHz).

So lets try other av201x driver that seems to be more recent, maybe it will work.
AVL6862-22.0.6.3.zip (530.9 KB)
To be sure that the new version is used please upload dmesg output and lsmod output.

[taki]

The symbol rate is 400 at the frequencies where it gives an error. Therefore, it gives an error below a minimum symbol rate of 1000. Another one gives an error because the lnbf downmix frequency is above 12739.

I will try

dvb_meson module from AV6862 addon was not loaded. I tested the last version on my box and for sure it works. I see no module load errors either so it seems like there is no addon installed or something went wrong during installation.

There’s probably a tuner lock, but the signal isn’t being captured. Some things have changed. The faulty tuner and demo range are displaying external frequencies and symbols. Also, although the tuner gives the voltage correctly as 14/18v on Android, when I measure it on CoreElect, the vertical voltage is correct but the horizontal voltage gives 16 volts. On Android, it gives 18 volts. 16 volts opens it but ..

[rozpruwacz]

I have no other idea. tried avl62x1 drivers from those two sources:

GitHub - availink/dvb-frontends-availink at...

GitHub - edision-open/dvb-frontends-avl62x1: Availink AVL62x1 S/S2/S2X demodulator driver and...

with firmware from here:

GitHub - availink/linux-firmware-availink at...

av201x driver also from two sources, from CE linux repo and from here:

GitHub - edision-open/dvb-frontends-avl62x1: Availink AVL62x1 S/S2/S2X demodulator driver and...

are there any other driver sources ?

[taki]

https://discourse.coreelec.org/t/dvb-s2-tuner-avl62x1-tv-headend-scan-problem/17436

This link shows that in 2021, in the availink repository, a signal was received with this avl6261 using the coreelec hack 9.2.1 build with kernel 3.14. The necessary dmesg and dts files are available, but they are for kernel 3.14. Again, the issue has not been further investigated. Commits · availink/CoreELEC_avl · GitHub

You should look at the patches and commits here. Although it’s not related to our main driver, it might give you an idea. I’ll look into it, but there are no other known open-source driver repositories. It might be somewhere on GitHub. It might be in an Android SDK.
