It's a little disconcerting until you go in and see how much code has changed.
As for the slowness with 4K, the subject of this thread which I imagine you haven't read to the end, it has been written that it also depends (but not only) on the DDR4 clock. the fix in question is being tested and will be released as soon as possible.
in the meantime, you can try this old test build and see if it improves anything
https://ilmich.libreelec.tv/test-images/roc-3328-cc/

Is that the same test build I tried earlier in a past reply? I remember trying one and it didn't really make a difference and wouldn't run at higher resolution (4K, was set at 1920x1200)

Does the RAM run higher than 800mhz? Or is that the max? I can't remember off top of my head what these boards run at. I thought higher but yeah.

What's the plan for seeing about the resolution being stuck at lower resolution?

Thanks!

Hey ilmich

Thanks for the reply. So the resolution is a much bigger problem with the linux 6.6 kernel? Interesting. Keep me posted on what you find out.

Thanks again!

Hey ilmich

Tried out that image. Loads up and menus work a lot faster but its locked at 1920x1200 @ 60hz. This while plugged into my 4K Dell monitor.

So far, progress but I'm assuming there can be fixes to allow higher resolutions. Even when playing videos that are 4K, I see it still at that resolution.

Oh, I also noticed CPU was running at 600Mhz. Is that correct? I can't remember if it was or not. I also don't recall the DRAM speeds but it was running a lot faster in the menus so I assume it was running at a higher speed too.

Thanks,

Furman

Hey ilmich thanks for the update. Dang, sorry to hear that it ruined the board. If you need any help or want collaboration let me know. I can build images also and am a developer in my daytime job haha.

Can't wait to test out what you do.

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK April 5, 2024 at 2:28 PM

Hey ilmich , did you ever get a chance to work on the board and a fix for it?

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK January 3, 2024 at 5:33 PM

Hey ilmich happy new years! Hope your holidays were good times. Glad to hear you have one arriving soon to test with. I have been away for awhile due to personal things, but let me know if you get a build and want me to test some. Thanks again.

Hi FurmanSK, the next step is to ask librecomputer folks to upstream some code for ddr3 reclocking.
I found the post you made on the board's forum and I seem to have understood that nothing can be done for now unless you use distributions based on BSP code (android).
I don't have your board so I can test myself.
But have you tried with libreelec 10?

Yeah I've tried LE 10, and I think it wouldn't even run at 1080p. Can't remember, been a couple weeks. Don't believe it would even play 4K ones on my 4K TV unless it would reset the resolution when playing but I didn't see anything in the whitelist for playback resolutions. I can try again but yeah I remember giving up once it had issues doing full resolution.

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK December 2, 2023 at 6:05 PM

Yeah I used that when I would build my own version of LE to try to include a realtek wifi driver for one I had laying around. Never worked fully and I gave up just cause driver support for them is shoddy. I meant more of the boot loader settings etc that he was changing.

Btw, ilmich put it on my sd card and both green and red led's light up, no HDMI output. So not sure what next steps would be. Wish had serial cable for it to see if anything is being output to serial.

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK December 1, 2023 at 7:37 PM

Alright, I'll give it a shot. I do appreciate it. And hey I'd like to learn how you did it all as a fellow software dev, building the OS from source and adding driver modules etc was interesting.

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK November 30, 2023 at 4:41 PM

ilmich Just checking in, any updates or things I could maybe help testing with? I could look at adding to my build server and see how the image works with building one up from source.

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK November 21, 2023 at 3:16 AM

What would be the differences with LE 10 vs 11/12? Besides kernel going to 6. Anything major relating to h265/HEVC or 4k?

Will give it a try and see what happens.

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK November 20, 2023 at 5:12 PM

I can't find any documentation that states what the DRAM should be running at natively. I also mentioned it to LibreComputers folks that the ram was running so slow and they were going to check with the LE team to make sure the right DRAM reclocking code was in the roc-cc builds.

Hi FurmanSK,
I've builted a version of bootloader with 534Mhz ddr4.
So first make a backup of your installation and after
- download this bootloader https://ilmich.libreelec.tv/rk3328/u-boot-rockchip.bin
- flash it in your bootmedia (from a linux machine or directly in a ssh session of your libreelec installation)
Code
dd if=u-boot-rockchip.bin of=${BOOT_DISK} bs=32k seek=1
where ${BOOT_DISK} is your boot device (for example /dev/mmcblk0)
If works you should see an higher pll_dpll in clk_summary.
Let me known.

Did you see my response ilmich ?

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK November 5, 2023 at 10:10 PM

Ok, so I tried it with /dev/mmcblk0 as thats what I had in /dev and rebooted. It did not come back up after reboot or even power cycling. Is there a way to put in linux and mount (I assume yes)?

ilmich

Don't you have an unoffical build for this chip?

FurmanSK · RK3328 4K HEVC stutter frame drop FurmanSK November 1, 2023 at 8:23 PM

So what tools are in place to do this on a nightly build of version 12? I couldn't find any tools that even let me see what the ram speed is at right now. I did ask this question on the Libre.computers forums and they said it wasn't an issue of overclocking and should ask the question here. Just need to know tools to use for it since its a stripped down basic linux and also if there are ways to OC things if needed.

That log didn't do any video playing either, so I could go back and try again right now and upload another log after a reboot to see if anything sticks out. I do appreciate your help Da Flex .

Can you reboot, and have a look at the next kodi.log? If the errors of #11 don't appear after that, fine.

Yeah here's the log. No errors like your original post.

Have you read https://wiki.libreelec.tv/configuration/4k-hdr ? - the configs discussed should generally help with most media playback.

Yeah, read over that first thing and tried stuff before opening a thread.

I'm not an expert of others rockchip socs, but with rk3228 (not the same of the one discussed in this thread) the only boards that can handle 4k contents are the ones with ddr3 and clock rate >= 600mhz.
maybe can be useful to check also type and clock of DDR RAM.

So mine is the https://libre.computer/products/roc-rk3328-cc/ which has ddr4. How can I go about finding the DRAM frequency? We don't have lshw installed. Not sure what other tools are installed since it is a stripped down linux.
