rk3318 is the little brother of the rk3328.. try the official ones for this soc. It's not guaranteed that everything will work but they should almost boot.

Hi, actually in the librecomputer source repositories I saw that I can try to increase the clock a little more.I'll do some tests.
Regarding the resolution problem with my monitor, everything works correctly with libreelec 9.2 (which has the vendor kernel). With all other subsequent versions it doesn't switch me to 720p (I don't have a 4k device). When you can, can you also do some tests with libreelec 9.2? Just to better understand if it supports all resolutions and therefore be on the safe side by trying to understand the differences between vendor and mainline (the drivers have been rewritten but the starting point is the kernel vendor)

chaconet please without logs I can't help you

on my boxes WiFi works as usual.

ham-egg-and-chips wich model of box? no particolar issue for me at 24hz.

Hi FurmanSK your observations are correct, in many cases the operations are accelerated via hardware (gpu, decoding) so before the bottleneck was the ram which at low speeds kept the cpu busy which had the task of waiting and synchronizing the texture movements and video streams. the ram now runs at 800mhz and the bottleneck has moved (even if with estuary I reach 30fps)
the resolution problem is known, from the little I've seen there is a regression in kernel 6.6 which has impacts almost everywhere. I'm trying to understand more

Hi FurmanSK,

let me know.

the new board finally arrived today. I tried libreelec 12beta2 and it works, but in my opinion it can be improved a lot. I will let you know

Hi FurmanSK the first attempt was bad (I think I ruined the board maybe using a bad power supply).. I have another one coming and I should be able to try and develop with this board.

Quote from LewisTowm

I need to use kodi for an old television and I saw that kodi 9 does work with AV, but without color

I'm thinking of porting that driver into the new release of libreelec 12. Anyway, what kind of standard does your TV use? Pal or NTSC, from what I have studied the lack of color may depend on the fact that the driver uses one standard, and the television accepts another. However, I haven't yet understood how to change the behavior (i.e. make the driver use one standard rather than another)

Quote from markosc

It is possible to enable other IR protocols to map another remote control?

Technically yes, but keep in mind that turning the box on via remote control only works with the nec/necx protocol(which is why the others are disabled). This is because it is implemented in a proprietary binary that cannot be modified.

And nothing pushed to github?

before releasing on github I do some testing on my boxes. anyway in the next few days, I will make the last release of 11 and it will all be on github too

miclass have you tried modifying the dtb? Have you noticed any problems? I'm about to release the last version of 11 (then I'll start with 12)

LewisTowm may I please know what you need it for? the analogic video output driver does not exist in mainline kernels, I could try to implement it but for now, I don't see the use for it

@reznik1988 A thousand thanks.

Hi miclass, try with this dtb (if you are booting from SD try replacing the file you find in the FAT partition).
I increased the clock of ddr3 memory. Since the faster the RAM, the less load is on the CPU, it could be cooler.

Regarding the heat sink, it's not difficult to remove it with pliers. You have to make slow but firm rotations and it comes off. But I understand your fear, I had it the first time too.

Ps: remove .txt extension

Quote from miclass

Happy to know it helped to solve a problem - I am curious to know what was the issue, something missing?

I've seen how DRMPrime works and for non hardware decoded videos it uses linux's dma heaps (which I didn't have enabled).

Quote from miclass

The processor become quite hot, I would like to had a little fan but I am wondering which is the best place on the board where to connect it.

I recommend you try a larger heatsink first

Quote from miclass

Anyway it's amazing what these boxes can still do today

The hardware has good multimedia performance. Add to that two years of testing and fine-tuning

Ciao miclass, I should have solved it. Please try this test image.

I have to thank you because you helped me solve a problem that has always been there in my builds.

Ciao miclass

AC3 -> doesn't work, no audio

please check the device used for passthrough in the audio settings. AC3 tracks can be sent raw to the connected audio device. Probably by default the spdif connector is selected instead of the hdmi.

Quote from miclass

XVID -> KODI simply crashes and it start agains (system remains up). If I disable the option "Allow use DRM PRIME Decoder", xvid someway works, but not great... (note: actually XVID was the problem, not MPEG4)

I'll do some testing and let you know. Thanks a lot!

EDIT: just for clarity, xvid is an optimized mpeg4 codec, for this reason I talked about mpeg4 in general

LewisTowm have you tried using the Libretro Kodi addon? However, I posted an unofficial build for rk322x on the lakka forum some time ago. Then I gave up because the box emulates 8 and 16 bit machines well. the rest is asking too much of these cpu

miclass another thing.. do you use the dts of the mxq 4k? or the generic one?

hi edinsac your box is an allwinner, so my build is no good. try asking in the appropriate section of this forum

keesijp60 unfortunately not, I need a driver (possibly updated to the latest versions of the Linux kernel). After doing some research I found one, but I don't know if it's usable.

BakaKilluaTo. get an SD card and write my image on it as indicated in the first post. I've never seen the box but it seems compatible (consider that the specifications I see in the link could be fake, I have never seen rk322x boxes with more than 2GB of RAM and 16GB of storage). I also ask you to send a link to the original version of the firmware so that I can study it better.

miclass The SOC supports hardware decoding for MPEG4, but I believe the software basis to implement it is missing in modern Linux kernels. I don't know the reason why no one has ever done it, but I imagine it's related to the obsolescence of the codec. The box restarts probably because it reaches high temperatures given that the decoding takes place via software. However, MPEG4 is quite easy to decode so I don't expect the CPU to be at 100% fixed. can you check this, please? maybe you can also tell me the resolution of the TV and that of the video you are playing?
