Hi FurmanSK, try

Index of /rk3328/

just to verify that my intuition is correct, I reused the legacy bootloader and ported a couple of kodi patches that are in Omega that increase performance.

Remember that decoding 4k contents and smooth UI at 4k resolution are different. So please try with a lower UI resolution, and let kodi player switch to 4k when needed.

Cheers
Michele

edit: if works share the output of cat /sys/kernel/debug/clk/clk_summary

hi digicroxx, try this

and let me know. In the meantime, I'm testing this oldest trust with my boxes.

Michele

FurmanSK if whitelist is empty you must populate it. But be patient, I'll try to build an unofficial build for you with some patches from my unofficial builds for rk3229.

chewitt I'm an hobbist and a bad developer, but I'll try. I'll try also to buy this board.

ilmich , I know your build are unofficial and some things are different, but since I'm not expert of official librelec either, it's not a big deal for me... From my point of view yours is the official repo .

it was to tell you that, for example, mogrify is a tool that I use to reduce the textures of the estuary skin so for those who build my repo it is normal.

And google is my friend expecially when I'm able to ask questions with enough details to filter out misleading links, so do you maybe have a good starting point to suggest for me to learn how to unpack h20 fw?

I apologize, but you have to understand that giving a hand to everyone by guiding them step by step sometimes becomes difficult for me (lack of time). however you can use rkunpackfw tool from this
https://github.com/ilmich/rkflashtool

if you want to try to insert it into the build you have to change here
https://github.com/ilmich/LibreEL…der/install#L16

fsdonato sorry, can you please explain better your use case(better if step by step)? I want to reproduce your issue.

digicroxx keep in mind that my builds are unofficial and some things are little different (90% of code are under projects/rockchip/devices/rk322x). I suggest to unpack h20 firmware (google is your friend) and flash trust.img on libreelec prepared sdcard. If works share results and I'll try to put working trust on my rkbin repository(source of binary bootloader and various wifi firmware) in order to test with others boxes.

thanks a lot

Hi all,

a new build of libreelec 11 available with:

- mesa 23.3.0 and kernel 6.1.63
- added bcm43342 wireless firmware (not tested because I don't have such chip)
- raise ddr3 clock (~650MHZ)
- added simple irqbalancer
- added 2 new mxq4k and mxq4kpro variant
- various fixes and improvements
- updated to latest libreelec source

!!! With this build I increased the default RAM frequency. I tried with all the boxes at my disposal without encountering any problems. However, it is recommended to make a backup or use another SD card. !!!

Some features are missing (like NAND).

My build of Libreelec 11 has some breaking changes that make it incompatible with previous Libreelec 10 builds. In other words, there is no easy way to upgrade your Libreelec 10 setup to Libreelec 11.

Cheers
Michele

fsdonato now your wifi should work. markosc issue with tvheadend has gone (almost on my boxes). usr4864 try with this build(possibly even in 4k because I've never tested it) , my t95d box (similar to your onetvlite) doesn't reboot anymore.

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?

FurmanSK try this build

I slightly raised the clock frequency to ~500mhz.

Quote from FurmanSK

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.

Hi, I'm trying to make you a new build by changing the frequency of the ddr3 a little. Please note that I don't have your board, so I can't guarantee that it will work. I'm doing this to try to give you a hand because these boards are phenomenal (I work with Android boxes with older soc) and sometimes you just need to tune them a little.

Fingers crossed
Michele

Quote from usr4864

the box reboots, i always use the device tree for my box.

it overheated, I reviewed the photos you sent and the box is nice aesthetically, but it will definitely have poor ventilation (like my t95d). I'll try to send you a dtb with a lower CPU frequency.

Quote from usr4864

Also maybe the reboot issue was because of this, i don't think this box is able to really handle 4K output.

Maybe I can get it going. I don't have a 4K TV so I don't do much testing, but with the changes I'm making the 4K HW decoding goes smoothly.

Quote from digicroxx

Has anyone already encountered the same problem?

If you are using my repo, I don't update it often. I did this a little while ago, pull and try again. In any case, in your case, the trust os must be changed. I have to try to see if it also works with other boxes to make the switch, otherwise, I'll have to invent something

hi markosc,

regarding the problem with tvheadend, which dvb device do you use? After many attempts, I changed the device (xbox decoder --> hauppage) and I had no problem. I suspect that the box doesn't provide enough power for that device, or is ruined, or there is a bug somewhere that has nothing to do with libreelec or the optimizations I'm carrying out.

Quote from digicroxx

If it can be useful, later tonight I can upload the flash backup I made from my box with mulitool; let me know if it's useful.

thanks but it's not necessary, the firmware is fine. Anyway, as soon as I can I'll try to prepare a version for you to try.

Hi digicroxx

the problem, which also emerged in the armbian forum, is that apparently this board only works with the 1.0.1 trust (libreelec mounts 1.1.0). I'm trying to figure out what I can do. Can you please share a link with a downloadable firmware of your box?

Quote from digicroxx

And would you be so kind to also suggest me some links to learn more technical details about the boot process of these SoC? (I would like to become more knowledgeable in this field...)

markosc

I recently made the famous discovery of hot water :). In practice, if the RAM runs slowly, the CPU has more difficulty managing the system. So while I previously thought that the CPU was too old to decode a 720 video via software, I realized that in reality by increasing the DDR3 frequency it does it just fine.

So in the dtb I passed to you, I raised the frequency of the ddr3 clock. I don't think this affects DVB decoding (I tried local video without any problems). I'll try to take a look at it because I also have the same problem as you, but I'm thinking more of an update to the addon than anything else. You can try either with older versions of tvheadend/pvr.hts or using iptvsimple client (tvheadend also exposes m3u8 lists)

Quote from markosc

Another detail I noticed is that in Netflix, if I want to resume a video that I previously switched from VP9 to H264, the TV box restarts. However, sticking to H264, I find it much smoother than before. Thanks.

I think is an addon issue.

cheers
Michele

hi markosc try the attached dtb

Quote from markosc

However, I have an issue with the Netflix plugin. When I activate VP9, the videos appear slow and the quality doesn't seem to be 720p. The CPU usage goes up to 220%. It seems smoother if I choose H264; however, the range is between 18 to 28 fps and sometimes it plays slowly. The CPU goes up to 350%, it appears smoother, but the image looks washed out and doesn't seem like 720p.

Hi markosc, it's a known issue, unfortunately. There are some addons, such as Disney+, which for some reason (maybe widevine license) use hardware acceleration for decoding. The Netflix addon does not, so the decoding is via software and with a single thread. For the moment I recommend lowering the playback quality. In libreelec 10 the clocks (cpu/gpu) were higher, but I realized that unfortunately due to the heat, the throttling caused artefacts. I'm trying to find a solution.

Hi usr4864,

it's a reboot of the box? or Kodi? which device tree do you use? Is the generic one or the one for your box?

I'll ask you if you can send me a log because maybe I can get the wifi/Bluetooth working too

missing firmware, in the next build your wifi should work

Can you please tell me if, also checking with Android, your board also has Bluetooth? What is the name of your box (not board)? Do the LEDs work well? Do you try to see by switching to other device trees if your box already has a good configuration?

I want to make a specific device tree, but I need this information.

Quote from anjarys

Hi, attached remote config for greenet.txt

Thank you so much.

Quote from anjarys

And it would be nice if you add wifi driver for SV6256P on your next build, too?

No working driver for now. I'll suggest to use ethernet, or external usb wifi dongle.
