Hi All

I have now some test done, like to find the clock pin of a chip who clock is below the chip and not reachable, I found

that the empty space for a normal memory chip did work, and have maskrom back.

I have tryed different libreelec images, but when I put it internal with multitool, it does not boot, or even did brick the box,

that is why i had to find the clock pin. On the arbian forum I had some help, but I need to be here because it is for a movie

box with digital out who drive later the dac i am building with tube outputs.

So have to test and learn.

keesijp60 Your box seems to have a type of internal memory called emcp (basically RAM and storage are in a single chip). I don't know if you can send the output of a uart serial, but I'll try to make some changes,
Regarding your project, time, and several versions of libreleec ago, a user connected an rk322x box to an amplifier through the spdif digital output.

Tanix TX2 RK3229 MPD DAC Hi Res Audio Bitperfect

I would like to explain my project for connect my Android box Tanix TX2 based on chip RK3229 with an amplifier DAC Sabaj A4 trough an optic cable.

The goal is use the Tanix TX2 like a server MPD for playing music in lossless Hi Res Audio.

the technical specifications of the audio part of the RK3229 chip are:

• I2S0/I2S1 with 8ch: supports up to 8 channels (8xTX or 8xRX). Audio resolution from 16bits to 32bits. Sample rate up to 192KHz
• I2S2/PCM with 2ch: Up to 2 channels (2xTX and 2xRX). Audio

Maybe you can take a look to understand the potential of your box (the instructions also apply to my builds).

ochentay4 Finally, some time ago I found a box identical to yours. So being able to do some tests I also managed to get the wifi working (but only on libreelec 11)
as regards the installation in nand (as in your case), from libreelec 11 it's no longer supported (as indicated in the first post that no one reads ). unfortunately, the source code is not available and with the new kernels, the nand binary no longer works.
Maybe one day this may change. But considering that in my case a couple of nands chip start to corrupt!!! So I always recommend installing it on the SD card because it's more manageable (backups, replacements, etc. etc.)

Hmmm I gess, pc say 64 Gb on a 8Gb minisd? I get kernel panic sync problem.

The V88 II tv box do work for MXqpro with volume on remote working.

Get full hd, but it crash after some 15 minutes.

The SD card is in a adaptor, I get in windows two drives visible with the same letter F.

broken sd card? can you please share some logs?

Hi chaconet keep in mind that:

- mine is an unofficial project done in my spare time so basically in the first post you will find some information, but if it is not clear please help me improve.
- the rk3229 was a very popular soc because it was very powerful and usable even now... this means that the variations are many and even if the images are nightly, I consider them stable on the boxes that I own. On others like yours, I need user support if possible.
- due to the previous point, I chose to consent boot of my images on as many boxes as possible, which implies that the CPU/RAM is not optimized because some boxes need particular device trees (the supported boxes and the procedure for changing them are in the first post).
- my build does not work if you try to flash device equipped with nand storage (which is not your case) but on sd/emmc it does. There is no automatic procedure within the build. But you can, after checking that everything works by booting to the SD card, flash it in various ways. This is not well documented because I recommend installing on internal memory only if you know what are you doing.

Said this:

- I'm preparing a device tree for your box (from the screenshots you sent it looks like a clone of the Tanix TX2) which I will ask you to try. In the meantime try changing the device tree following the table of the first post keeping in mind that your box has the ddr3 memory type (which makes everything faster but disabled on generic device tree)
- if you want to install libreelec in the internal memory you can do it with the multitool (https://forum.armbian.com/topic/12656-cs…k322x-tv-boxes/). The procedure you find to install armbian also applies to libreelec (you just have to use my images)

Hi all,

a new build of libreelec 11 available with:

- mesa 23.3.6 and kernel 6.1.74
- added RTL8812CU usb wifi driver (untested)
- various fixes and improvements
- updated to latest libreelec source (11.0.6)

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

edit: I'm starting to work on libreelec 12.

Hi keesijp60

I don't quite understand, does your box go to maskrom because you deleted the internal memory? or does it go there on its own, a sign that your internal memory is broken?
Another question, does the multitool tell you that your box has NAND as storage type? Because in that case, you can't install libreelec in the internal memory, but you can only boot it from the SD card. Let me know

hi chaconet, please send me some log, wifi model etc etc

Your box seems a clone of tanix x2 that should works.

Hi areq1987, Libreelec is an optimized for kodi linux distribution, not an Android custom rom.

You must

- create a bootable sd card (follow instructions in the first post)

- connect the box to a network and login as root with ssh

- switch from generic box to mxq pro 4k(or the one that works for you)(follow instructions in the first post)

- enjoy/report bugs

hi thisispatrick unfortunately without an open source driver it's impossible for me.

regarding ethernet, have you also tried with libreelec (installed on the SD card) and saw that it doesn't work?

Quote from presko

Can i clean install libreelec 11 on the emmc or it can run only from SD.

hi presko, yes of course, my build no longer works if you have a device with NAND storage type. but with the emmc it works like previous builds

Quote from presko

Its most likely that wifi will start when i update to ibreelec 11. Or the firmware shoud be integrated in future update of the build.

for the RTL8821CU chip I will try to include it in the next build, which I have planned soon, but you will have to help me because I can't test it.

edit: try this build https://ilmich.libreelec.tv/libreelec-11/test/

hi LynxChaus , the legacy rockchip kernel (used by libreelec 9.2 builds) sets the resolution to 1280x720 if it doesn't read the edid. the mainline kernel instead (used by my builds) does the same thing but sets a lower and more compatible resolution.

Some users have had the same problem as you in the past, but I preferred not to change the behavior of the kernel because you can follow this guide (read carefully because some commands are exclusively for x86/x86_64 architectures)

hi szczur3k, can you send me a log, please? I saw that that driver is now included in the kernel and I enabled it. I can also enable another one but I would first like to understand what problems it has. Thank you

Hi usr4864  piotrekg1984 , in the next build I'll try to go back/improve some changes. In the meantime, can you point me to a better version by trying the previous ones?

usr4864 from the log I see, Kodi crashed while you were configuring something, but I don't rule out a bug. It also happened to me once while configuring the IPTV client and I 'solved' it by reformatting the SD card.

Hi all,

a new build of libreelec 11 available with:

- mesa 23.3.2 and kernel 6.1.68
- preemptive kernel for better performance
- various fixes and improvements
- updated to latest libreelec source

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.

fsdonato I'm very sorry, however you can continue to use libreelec via SD card (which is much better because you have no space limitations given that there are SD cards of 128GB and above). it's a shame to throw it away

Hi punter, update libre11 from libre10 is not supported because I've renamed the device trees.

you must manually reselect the specific device tree of your box as described in first post

Now I have Armbian with kernel 6.1 working fine (my falut, I didn't reset internal eMMC; I thought sdcard had priority during boot process).

If I remember correctly, the boot sequence always starts from internal memory, and then from a certain point onwards, it goes to the SD card. This causes problems with old bootloaders (as in your case). So either you update what is in the internal memory, or you reset it so that it takes everything from the SD.

Quote from digicroxx

Librelec is still stopping a few rows after kernel start, but now I have a working dtb to try and compare, so I think I know how to proceed.

Good, from the error I see that it could be a problem with the cpu frequencies. Try removing the cpu0_opp node.

Quote from digicroxx

Should I expect to have also the early boot (minloader-ddrbin-trustos) at 115200? Now this is 1500000.

Trust is a closed binary, but for ddrbin there is a tool that configures these things. so I would tell you that if everything went well everything is now at 115200.

Quote from digicroxx

Don't worry, you already helped a lot. I will continue by cutting branches on dtb (or merging from the one I've extracted) and maybe also trying to boot Armbian (if it really works) to compare things. I will keep you updated.

If you get Armbian with kernel 6.1 (should be the stable one) the dtb is compatible, jock2 and I exchange information.

Quote from digicroxx

Btw, the log of uboot is still at 115200bps, maybe something is missing...

it's normal, now everything is at 115200 (as it should be). regarding the device tree you have probably studied, but they are files that describe the device (how many USB ports it has.. if it has HDMI.. internal storage.. etc etc)
Unfortunately this week I'm busy at work, and I don't know how much I can help you (having said that without device was hard for me). However, I advise you to take the dtb of the latest build that I sent you, decompile it (there is a tool called dtc), and try to remove some pieces (for example the part that indicates the CPU frequencies).
However, if I think of anything else I'll let you know.
