    hi markosc,

    thanks for the invaluable support. So from what I understand

    rk3229-box-v88mars works, slow but works

    rk3229-box-mxq4kpro works but crash

    rk3229-box-v88mars-ovclk / rk3229-box-v884k-ovclk works but crash.

    I ask you for the latest test, to rule out application bugs.

    Inside the extlinux.conf file add the parameter cma = 128M. Here is an example

    Code
    APPEND boot=UUID=3003-4337 disk=UUID=7e1f7cb6-2d57-45d8-bc99-ac316c2f31f6 quiet console=uart8250,mmio32,0x11030000 console=tty0 cma=128M

    If even so, you have problems, I try to generate a dts starting from libreelec legacy.

    I changed some voltage values to reduce the heat generated (libreelec legacy is a furnace)

    Welcome AllanK

    my goal is to have a stable build. I have 3 boxes, one of which is used regularly as a media center without any problem.

    Clearly supporting all existing variants is complex, and user support is key to solving problems that I can't test.

    But libreelec mainline is the future.

    So in the best case, your board will run smoothly and you will be satisfied. Otherwise, you have to be patient and help me figure out how to solve problems.


    edit: Take a look here too, Tanix TX2 RK3229 MPD DAC Hi Res Audio Bitperfect. A user has turned his rk3229 box into an audio system.

    Cheers

    Quote from Harleythetech

    i guess the limitation is really on linux compatibility with the box

    I'm curious is there anyway to make the cpu run at full 1.5GHz all the time? I found that when you run the CPU at 1.5Ghz all the time on armbian it makes the system a bit more smoother than having it jump around frequencies.

    I'm still using the last test build you sent me.

    It is a collection of things in reality.

    More complex software, opensource driver based on reverse engineering (longer development times, especially because the mali400 is rather old and therefore less interesting to evolve), etc etc

    For example, I have a lakka build somewhere, and the ui is very smooth because it is less complex than the kodi one.

    But supporting mainline development has enormous benefits.

    Because you can reuse your box indefinitely (or almost) and for anything (mediacenter, nas, home automation, music)

    However, to get the cpu up to speed, launch this command from a terminal

    Code
    echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

    put in

    Code
    /storage/.config/autostart.sh

    if you want to be automatically launched at boot

    hi markosc,

    thanks for the logs. For the boot problem, I think it needs to go back to the initial voltages because they don't work for everyone.

    For the other problem, I saw an error in the kernel graphics driver. I'm trying to figure out what it might be about

  • [UNOFFICIAL][Le11-10][RK3228/RK3229][box]Libreelec builds

    I repeat myself too, show me the error. It could be a voltage not compatible with your card (I have 3 boards and it seems strange to me)

    . But you understand that it's hard for me when someone says .. it doesn't work, but then it disappears or doesn't give helpful information.

    If, on the other hand, it's a voltage problem, use the dts of the version that works. In other words copy the dts from july version (you can find them in the .tar version of my builds)

    But again, without the system logs, you can write anything, but I can't help you / improve my builds.

    You always do it, you say nothing works but then you don't help me understand.

    thank you

    Hi all,

    new build available with:

    - linux 5.10.142

    - removed esp8089 wireless linux driver (not working)

    - added rtl8192f usb driver

    - better emcp support (thanks @Harleythetech for testing)

    - mesa3d 22.2.0

    - revised cpu/gpu clocks and voltage

    - new kernel config

    - small fixes

    This build contains some substantial changes that have been tested for over a month on my boards that I use on a daily basis, with no obvious problems. However the suggestion to try it on the SD card before updating is, for me, mandatory.

    I also rented a small server to publish my builds and save valuable space on my personal google drive.

    It has few resources but if I realize it is necessary, I could think of an upgrade.

    Cheers

    thanks MIKMXIII , these days I'm improving the temperature management, also adding the throttling of the gpu.

    it has never happened to me, and no one has ever managed to give me a log, but with my builds the kernel restarts the board when the temperature exceeds the 100 degrees celsius.

    but let's say that, thanks also to latest evolutions of the opensource mesa 3d driver, the board is much better than when I started this project (I'm experimenting with a build of lakka 4.2 and I'm quite surprised)

    as for your problems, unfortunately if you use streaming, but the source is not stable there is little you can do.

    on the analog audio switch, honestly I don't use it daily, but I'll do some tests and let you know

    Thanks again

    hi remlei,

    my builds by default use a generic device tree.

    The supported devices are only customizations for various leds layouts and ddr3.

    So you can try first the generic one to check if all works well, and then try another dtb to find the best for your device.

    If you don't find the right one I'll try to produce a dtb for v88 mars 2 (link for official android firmware are appreciated).

    cheers
