Did you compile your armbian OS with linux 6.15.x? https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/#findComment-216587

Our release will also be around Noble / Trixie + minimal image with Bookworm. For those that wants to stay on a safe side x86 images were already released: https://www.armbian.com/uefi-x86/ and few others ...

@Thiên Thư Lục USB3 is little half working and i have USB-3 HD/SSD and its freezing some times but normally Armbian is running stable on it. Also general devices in the USB3 jack is freezing like SDR dongle stop being recognized then being pullrd out and in agenand need one repower of the box for getting the USB3 jack working agen. The factory Android bootloader is not supporting USB boot only SD-Card or eMMC . Write one updated / new on the eMMC (can soft bricking the box) or erase the eMMC shall doing it then the chip is loading it from the SD-Card if not found eMMC. Also putting in one SD-Card with updated boootoader and it shall being possible "jump starting" to USB devices like sticks and HDs from the SD-Card.

@robertoj right, that worked for me as well But the remaining issue is the slowness. Meanwhile I also tested ffmpeg unscaled and no rgb conversion to /dev/null outputt but still slow. Maybe there is some pre/postprocessing done which cloud be tuned further. If i remember right there are some v4l2* features which may impact the processing but I'm not sure if this was camera capture related. Another idea: It seems the VPU clock source is configurable (inside DT) maybe that's not quite right? T.

@Nick A sorrry but i didn't found where you replied to me could you repost it to mine trhead?😁

Thanks for noticing me!!! I will check the last thread ive been in and the dram settings and dts, i havent checked also i cant edit/change dram and dts, i use windows but i will use a virtual machine to get the armbian doing its job. and from the secure boot, it could be because when i do the “toothpick method”, it showed the updating screen but nothing updated thanks you for replying to me edit: is the text too blurry? I could take more 😃

The helios4 is on its way to @laibsch. It is not available anymore...

Some fixes are kernel specific. If I understand correctly, the "memory-region" is only necessary when using the legacy cedar driver with a more recent kernel. It is supported up to kernel 6.1. You can confirm CMA allocation by running "sudo dmesg | grep CMA" or by running "cat /proc/meminfo | grep Cma" That's interesting, although cedrus only acts as the video decoding engine while the display engine is responsible for the actual rendering.

@Ducdanh Nguyen @ccs1664 is correct.. there’s a lot of information on that thread and the x96q threads to get your box running. I have to post the same advice over and over again. The last thread you posted in. I gave instructions to get your dram settings and dts. Have you extracted them? it could be possible that you have secure boot.

yep, thats how i connected them i think it might be that? ill try to get some fresh wires and see if it helps

Your gpios lines are declaring reset="i6" and dc="h4"... is that correct? At this point, we can see that all pins are correctly defined and connected. Maybe wire length issue? Bad terminal connection? My wires are 15cm long... directly connected with dupont connectors.

Boot while looking at the serial output, what do you see?

Self compiled Armbian Bookworm + XFCE with Linux Edge 6.15.x Then follow all the instructions in https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/#findComment-176981 Then add extraargs=cma=256M to armbianEnv.txt

Which OS works well for you?

If it doesn't work, compile your own Armbian with EDGE linux (what worked for me). Stay away from Trixie at this time (its mpv doesn't work as well as Bookworm's)

Great, thanks for the links! Meanwhile it works partially. The DT tweaking was not needed. I made a mistake by specifying the armbian extraargs. I added a second line to armbianEnv.txt but realized all args must be one line. I had to increase cma=256M (Yes, really, tested all lower values). Then it works, BUT ... Fun fact, will further investigate: Decoding with "-hwaccel drm" results in lower fps (about 6..8) whereas software decoder goes up to 10 😀 Decoding has been verified with htop. CPU only => 4 cores 100%. hwaccel one core about 20% which is likely th e yuv to rgb and scaling. Maybe this is still an issue caused by DT, at least when reading https://gregdavill.com/posts/allwinner-s3-videoencoders/ It specifies memory-region = <&cma_pool>; which is missing in my decompiled DT, also the referenced reserved-memory section. Maybe that's not needed if it's coded inside the driver or specified elswhere. T.

I also confirmed that USB-C functionality is still not working on ODROID-M2 with Kernel 6.16 RC. I guess we would have to wait a little more for the working USB-C Port.

@ccs1664 thanks for the information, but i already have a image that works on my mxq pro 4k 5g allwinner h313, but im struggling how to boot in the sd card, and i cant enter recovery mode too (it showed an update screen but nithing updated) im glad you replied to my situation.

Depending on your location this might not be anything that can be fixed on Armbian side. If this happens on any mirror, the issue is either your setup or ISP blocking access.

Regardless of whether I use the main or v25.08 branch, set REGIONAL_IMAGE to china or not, or switch between noble and trixie base images, I consistently encounter a 403 Forbidden error right after the customization step. I've tried various configurations, but the issue persists. Any help?🤔

@rafaeldavid My device appears to have the same problem as yours. What was your fix? @Nick AThanks! The chips on the motherboard include H313, AXP313A, KMQN10006B-B318, and EA6521QF (Wi-Fi + BT chip). I have the Linux driver package for this Wi-Fi chip. this Wi-Fi chip (EA6521QF) likely isn't supported by mainline Linux kernel.I’ll figure out how to integrate it later when I need to use Wi-Fi. Using Wi-Fi is not the most important thing; the key is that I want to install it into the eMMC instead of booting from the SD card. May I ask what modifications I need to make to the original Armbian project code based on the dts I provided to ensure stable read/write operations on the eMMC without crashes? Moreover, I've already tried using a different TF card. These same cards work fine when installing to eMMC on my other X96Q (DDR v5.1), but they keep freezing up on this device.。 dmesg.txt

Latest edge kernel update to 6.16 breaks boot

Hello, I have x96q2 H313 2/16 board v4.0 ram k4b2g0446c hyh9 and apx305. I tried all img, and no one worked on my TV box. Mb u can help me, how I can build img for my board? I need sd card version armbian or arch Linux (not emmc installation)
