The kernel headers that you have installed are quite enough to build the kernel module, the source codes of which you have. If the source codes are already in the kernel, then you just need to configure the kernel before compiling. launch: After you finish the configuration, the build system saves your configuration file (it will tell you where it did it). Save it under the name ./config/kernel/linux-sunxi64-current.config It is assumed that you are in the armbian/build directory. launch: ./compile.sh BOARD=orangepizero2 BRANCH=current kernel

Try some of these images. https://github.com/armbian/os/releases/tag/25.5.0-trunk.507 And please post here what doesn't work with the download link to the image.

Today 6.12 is the current kernel.

1) Play (decode) video audio 2) Read the status of multiple sensors at regular intervals 3) Generate pulses on GPIO 4) Transmit the packet at the right time over Ethernet, UART ... 5) .......? diff -u config/kernel/linux-sunxi64-edge.config userpatches/linux-sunxi64-edge.config

Have you tried applying this to the 6.12 kernel?

What is the purpose of using this core? Several people have already tried to build a real-time kernel here on the forum. They all face some challenges. Perhaps, if the tasks that such a core should perform are of a general nature, we can provide a configuration for its assembly. You built it yourself. Can you provide a difference in the configuration file for the same kernel version? As diff -u command.

A little clarification. Just install the EDGE core. The version must be 6.13.11 or higher.

kernel version? uname -r

This means that the missing pins should be written something like this: fragment@0 { target = <&spi1>; __overlay__ { status = "okay"; #address-cells = <1>; #size-cells = <0>; pinctrl-names = "default"; pinctrl-0 = <&spi1_pins>, <&spi1_cs0_pin>, <&spi1_cs1_pin>;

Try adding this line compatible = "armbian,spi-dev"; /dts-v1/; /plugin/; / { compatible = "allwinner,sun50i-h616"; fragment@0 { target = <&spi1>; __overlay__ { status = "okay"; compatible = "armbian,spi-dev"; cs-gpios = <&pio 7 9 0>,<&pio 2 15 0>; // PH9=CS0 for lcd, PC15=CS1 for touch panel: panel@0 { compatible = "panel-mipi-dbi-spi"; reg = <0>; ................ P.S. I doubt that I am giving you the right advice.

Yes, please post it here. There may be several suggestions (explanations) as a short instruction for use.

@jock Thank you for the opportunity.

Allwinner h616-h618: After this pull request pull/8086 the 6.13 EDGE core supports hardware decoding. You can use the instructions: repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner Enjoy your viewing.

@Marco Cettina When you apply the overlay, the PWM driver will loaded and export some files to /sys. I haven't figured out what to do with it next or how to use it yet. I hope you can clarify this for all of us. PR: pull/8086

https://github.com/The-going/PKG_test/tree/master/sunxi64-6.13 You can install these pre-assembled kernel packages and check their functionality. /boot/armbianEnv.txt ... overlay_prefix=sun50i-h616 overlays=pwm1-ph3 ...

As a rule, you also need to set the processor frequency to the maximum value and make it unchanged and configure the Linux kernel scheduler.

After you complete the configuration of the kernel, the build system will tell you where and under what name it has saved your configuration file. Next, you need to save it with a name config/kernel/linux-sunxi64-edge.config and commit it to the build system itself. or save it under the name userpatches/config/kernel/linux-sunxi64-edge.config Only after that, run ./compile.sh BOARD=bananapim4zero BRANCH=edge kernel

Indeed, I wrote it very briefly. There are problems with analog audio output/input in the linux kernel for h616-h618 processors. We are solving this problem, which exists in several drivers and their interaction with each other. Audio output via HDMI works today only because one of the Armbian users added this feature. This is an expansion board. Obviously, in order for it to work, we need overlays for everyone. sun50i-h616-audio-out.dtso /dts-v1/; /plugin/; / { fragment@0 { target = <&codec>; __overlay__ { allwinner,audio-routing = "Line Out", "LINEOUT"; status = "okay"; }; }; };

The driver in these kernels works well for "old" 1080p monitors. It has been verified that it does not work with SAMSUNG, LG 2k, 4k resolution models. This problem is in the drivers You can set in the file /boot/armbianEnv.txt verbosity=10. The output of this command in a working and non-working version may possibly suggest which of the driver modules is failing. dmesg | grep -E 'hdmi|drm|gpu|edid|cec'

The possible problem is in the u-boot loader. In order to understand what the problem is, we need a boot log from the UART console.

Please be patient. We are working on it. First of all, it will be added to the EDGE core.

The pwm driver is present there. It is necessary to add the overlay correctly. Is your device an orange-pi-zero-3?

I wrote it in a private message.

This is an outdated core and will no longer be supported after this pull request. Try switching to the EDGE core (6.13). I will add the ability to apply overlays for PWM to the EDGE core. And we will check it together.

variant-1 I didn't check it. Use it at your own risk. P.S. This will not work in the Armbian core at the moment. Further development is required in the sound/soc/sunxi/sun4i-i2s.c driver, with a cursory reading of the source text.
