Amlogic S905 android BOX DVB not found

i try the coreelec on my android box and the DVB not found.
The device made with Amlogic S905 & tuner AVL6211 (used in many amlogic devices).
and i have dtb.img extracted from its original firemware of android.
the coreelec booted and worked with gxbb_p200_k1_plus.dtb & gxbb_p200_1G_100M.dtb & many other device tree but the dvb not found
i ask for any help to make the dvb worke for this device.

I look in my crystal ball and I see gxbb_p200_1G_1Gbit_ks2.dtb

this dtb.img i get it from its android software

http://www.mediafire.com/file/4bg78p6gxg3n556/dtb.img/file

using gxbb_p200_1G_1Gbit_ks2.dtb make the LAN not work.
i cant access the tvheadend page or download any addons

I found that the dtb.img little bit similar to K1 (AVL6211&LAN&S905) and much more for K2 but this last is S905 and cant boot at all.

Pls provide kernel log dmesg | paste for both dtb’s. Try to use wifi connection for ks2 version. I think your box is Sen5 SH6B7FA https://www.cnx-software.com/2017/04/03/sen5-dual-tuner-android-set-top-box-review-part-1-unboxing-and-teardown/#sen5-sh6b7fa-tv-box-teardown

I dont see the AVL6211 in the kernel log.
the coreelec doesn’t support this driver or what?

this source code wirh AVL6211 driver maybe can help

this source code is found too


and this is a firemware

and there is some enigma 2 source code with avl6211 driver like openpli

I don’t need sources for AVL6211. This driver is already in CE. Wetek Play 2 uses this chip for DVB-S.
I need kernel log immediatly after rebooting box (< 30 sec), otherwise log is overwritten with a chunk. I need also report what is working with gxbb_p200_1G_sen5.dtb ethernet, wifi, bluetooth,…
I don’t need Kodi log !!!

I added serial transfer support for AVL6211. You have upgrade to the latest nightly builds and switch to dvb drivers addons, use dvb-latest. Update dtb gxbb_p200_1G_sen5.dtb (39.9 KB).

thanks for helping
the DVB not found and still real problem with the same message at startup “you are using an unsupported DTB”
i try the gxbb_p200_1G_sen5.dtb (39.9 KB).
with the default drivers
http://ix.io/1LY1
with the dvb driver from lastest kernel.

Sorry, I used GPIOZ_5 instead of GPIOAO_5 for demod reset pin. It is necessary set correct reset pin, otherwise demod is in reset status by default. Try gxbb_p200_1G_sen5.dtb (39.9 KB).
