I download the android DTB file to extract the DTS for my Tanix TX6 using my box.dts is Can this dts be used by armbian as it looks different to the existing dts i seen. ??

and firefox 😁

Sunxi-Cedrus is an effort to bring hardware-accelerated video decoding and encoding support for Allwinner SoCs to the mainline Linux kernel. Additional userspace components that interface with the kernel driver are also provided, for typical GNU/Linux-based systems. https://linux-sunxi.org/Sunxi-Cedrus

@vitya you could try this

still trying to get my bluetooth working on Vontare H618. could not power it on. renaming from uppercase filename to lower case allowed me to turn it on. BCM4334B0.hcd to bcm4334b0.hcd still unable to discover and connect. log of dmesg | grep -i bluetooth when uppercase BCM4334B0.hcd it found firmware patch ,but bluetooth power on failed when lowercase bcm4334b0.hcd not found firmware patch but bluetooth power on succeeded think patch / filename needs to be checked or matched.

I using build 240909 with Kernel 6.9.12 and edge ubuntu noble and i do not have hardware accelerated video and no Blue Tooth. Xtal usually alway measured in MHz, except for "clock" Xtal used in clocks and watches. 32.678 kHz size 3x8mm

No that Xtal is 37.4MHz or 26MHz used to generate the 2.4 and 5GHz radio fequency. (If no Xtal is used it be using internal oscillator or 24MHz from H618 cpu Xtal). The Low Power Clock, LPO is used to Clock the wifi chip when off/sleep and turn wifi and bluetooth on and off, 3 clk pulse after the voltage rails are turned on or off. When on it uses high speed clock from Xtal. See Page 17 of datasheet. Its Input Pin 24 of Wifi/BT chip, clk comes from H618/H616 arm CPU. Pin 24 LDO is marked with Pink dot.

@Nick A Vontar H618 HK6334Q this is from data sheet: "Pin 24 LPO External Low Power Clock input (32.768KHz)" measured with Owon HDS2202S hand held Oscilloscope. its 32.768KHz NOT 32kHz AP6330.pdf

i like to make a bootable micro SDcard with the Vontar H618 Android 12 firmware and see if it would boot on the Tanix Tx6. Use Disks to make an image and restore to sdcard?

Found this by searching vontar h618 firmware. https://androidpctv.com/vontar-h618-firmware-update/ And https://www.vontar.cn/pages/download

Vontar H618 working with transpeed,8k618-t image. wifi working with brcmfmac4334-sdio.transpeed,8k618-t.bin bluetooth does not work but icon appears in task bar I had to install no internet apps for desktop as armbian mirror for firefox is broken as there is file size missmatch and it cancels the compile of image trying to instal firefox by apt or synaptic package manager gave same error. I had to install firefox nightly to get a working browser.

Vontar H618 PCB: FX-H618-D4_V10 23-03-21 Ram: 4GB (8 x K4B4G0446B HCK0) Rom: 64GB (KLMCG4JENB ) Wifi: HK6334Q Osc: 37.4MHz LED: FD650B-S PMIC: AXP313A Android 12 is much better than Android 9 on my Tanix Tx6, better ui and more responsive. I will test with default transpeed-8k618-t image.

I have Tanix Tx6 and now a Vontar H618. which just arrived. I will check out your build. I cant even detect Bluetooth device. I need to dump my android DTS. looking at the AP6330 (SP6330) datasheet wifi/bt chip uses External Low Power Clock input (32.768KHz) and External Xtal Osc 26MHz. AP6330.pdf

regarding dts files, are the uboot and kernel dts files meant to be identical ? useful link about dts to/from dtb compiler. https://stackoverflow.com/questions/21670967/how-to-compile-dts-linux-device-tree-source-files-to-dtb
