A long time ago, I made an armbian guide, which included adding a kernel patch. Can you try this method? "Move them* to ~/armbian-2023.05/build/userpatches/kernel/archives/sunxi-6.1 (using the scp command or sshfs)" * would mean the cpio file (use diff3 to convert to patch file**) and any linux configuration patches needed to make your initramfs. ** diff3 linux_orig_source_folder linux_source_folder_with_cpio_file https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/README2.md#73-add-the-tv-encoder-driver-to-the-linux-kernel-source

If you don't have X11 or Wayland, try using the linux command "fbi" (frame buffer image). I think I put an example in this trhead or in the Banana Pi ili9341 thread (in this allwinner forum section).

Does anybody know if this will work with Allwinner H618?

Forumtrekker: I am 99% sure that if you see the LCD working OK once, with kungfupancake or any other a txt/bin file, for just console text, it will work for any graphics. There's an issue with plymouth: it modifies the initrd in a way that it loses track of the bin file, and the kernel driver fails to load. See: https://forum.armbian.com/topic/53568-how-to-add-a-specific-single-file-in-the-initrdimg-ideally-automatically-with-update-initramfs/#comment-221767 I am running my SPI at 40MHz fine with 20cm wires. I don't have time to see your DTS file, but are you using the same CS pin as I do? I have noticed there's a default "chip select" pin, which makes everything work better. If you are using panel-mipi-dbi driver, don't use any additional DTS for the LCD, not even additional SPI DTS, and armbianEnv.txt that refer to the LCD. According to the notro wiki, the ili9486 and ili9488 will only work with RGB888 mode (because we use SPI). There's the "format" parameter line just for that, in my DTS. Can you send a good photo of your LCD front and back? My method is for a Red PCB LCD. I don't know the brand, but it is not Waveshare, Creality or any known company. Sorry, saying "Chinese LCD" is like saying "wet water": redundant and not specific. pami: the english in your post is fine, but you can separate ideas and separate processes in paragraphs, to let me focus in one problem at a time Many LCD guides, due to being so old, use the fbcopy driver, or another "classic framebuffer" driver. I could make my ili9341 work with it, but since I learned to use the panel-mipi-dbi I only started using that. It get's you more fluid animations and probably Linux will prefer it in the future. If one dtbo file and a python script makes your LCD work fine, share that script and DTBO (best if you can decompile the DTBO into DTS), in this thread, as attached files. Send more photos of your LCD. AI suggestions will only work if the solution is well documented somewhere in the internet, and the AI has found it. AI will re-word the answer and take credit for it.

I see that this configuration is a kernel build feature, not an armbian-developed function: https://cateee.net/lkddb/web-lkddb/INITRAMFS_SOURCE.html https://unix.stackexchange.com/questions/479415/how-does-linux-know-where-the-rootfs-is So, you can post your question in many more linux discussion places. I hope you get the answer (and share here). Have you ever got this INITRAMFS_SOURCE configuration work, outside of Armbian... for example building the kernel from source by itself?

Try a different microSD card, and always start with a serial-USB connection to your laptop. After first boot, run htop and if you see the CPU high usage, wait until it is done. Then reboot the orange pi.

I don't know about customizing the initrd during the armbian build process. But this is the way to customize it AFTER you get armbian running in your board https://forum.armbian.com/topic/53568-how-to-add-a-specific-single-file-in-the-initrdimg-ideally-automatically-with-update-initramfs/#comment-221767 I know it is not YOUR OWN INITRD, but maybe you can work with it. Large language models are more useful when the answer exists somewhere in a popular website. If no human has written about it, ChatGPT or Gemini will not give you the answer. Have you tried replacing the uImage file in the /boot folder, with your own initrd, converted to uinitrd?

The ffmpeg conversation in https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20847 suddenly stopped 2 weeks ago. Does it seem like there's a big obstacle suddenly, or just a well deserved engineer vacation going on?

Thank you for testing my instructions I was on vacation, and I didn't remember to check this until now Which LCD are you using? Which kernel driver are you using for it? All the questions in your post depend on the LCD model and the driver you used. (I am using panel-mipi-dbi, which I know that it has lost its ability to display X11 graphics since a few months ago) Can you 100% say that you don't have X11? You don't need to use the same kernel version I use. The newer version you have is preferable 🆗 I am glad you can use the Trixie labwc. Personally, I am using Bookworm in the meantime, since its the only way I know to get H264 hardware acceleration. With Trixie's labwc, do you ever get desktop crashes when you log out?

mpv has the correct code to use the ffmpeg for cedrus hardware acceleration AND the correct code to display it on screen with minimal CPU usage. If you want gstreamer as a video pipeline, can you try using ffmpeg (the v4l2request version) and gstreamer together?

If you use your own boardconfig file, or edit another boardconfig file, you may be missing some configs or device tree overlay, and make problems in configuring SPI and GPIO pins. I always use boardconfig that's included in armbian-build, specifically for Orange Pi Zero 3, by following the text menu, and not editing any file.

All this time, I thought you were using a custom H618 board hardware. Now it is clear to me, that you have an Orange Pi Zero 3, In armbian build, make sure you don't add any configuration files. Just do "./compile.sh" and when you get the menu for board selection, press the button "Unsupported/CSC" (or something like that). The text menu will turn red. Press OK and you will see a list of more Linux boards. Press "P" to quickly scroll down, then "UP" to find Orange Pi Zero 3. Then choose the option for Linux edge, and choose that you want to configure linux.

Can you get an orange pi zero 3? As a hardware beginner, you need a very stable, well known linux board.

Alright Did you ever make this LCD work with your H618 motherboard, with another kernel driver?

Try the X11 windowing manager or the Wayland compositor without lightdm (or another display manager).
