    Hi, I try to briefly explain the problems you are looking at.

    Unfortunately, although I receive boxes from time to time, I don't have all the variants :(

    Anyway if

    - the box does not start or you see errors --> cpu voltages

    - the box freezes after a while (you notice this because the led that usually flashes when you use the remote control, stays still) --> gpu voltages.

    - kodi restarts --> generic bug that may depend on corrupted file, unstable network, etc etc. However bugs that do not directly depend on the build (almost 80% of the times).

    To solve the overheating problems, over time I have experimented with different voltages from the official ones and I thought I had found working ones more or less everywhere.

    Instead, some time ago I received a box that crashed on boot and therefore with the January release I fixed a little bit.

    Unfortunately in February I did another experiment and now you have problems.

    My suggestion is to stick with the January release and better specify what happens to you (if it falls into one of the cases that I have indicated to you).

    I also ask you to send me the output of this command (from an ssh shell inside the box)

    Code
    hexdump /sys/devices/platform/11040000.efuse/rockchip-efuse0/nvmem

    this is the internal rk3229 efuse, and inside there is the information to check if your box tolerate some voltages or not.

    Cheers

    Quote from dan25

    Hi ilmich ,

    Would you be interested in supporting the Grandstream GVC3212 perchance? Here is its vendor page, firmware, FCC documentation, and it appears to have an RK3228H chip onboard.

    Hi dan25

    all Rockchip devices work pretty much the same, so it wouldn't be impossible to do.

    And it would be nice to do so, unfortunately without the device available it's difficult to test everything.

    I found a tool

    Grandstream-Firmware-HT802/FirmwarePatcher at master · BigNerd95/Grandstream-Firmware-HT802
    Grandstream HT802 Reversing - Custom Firmware - Decrypt - Unpack - Grandstream-Firmware-HT802/FirmwarePatcher at master · BigNerd95/Grandstream-Firmware-HT802
    github.com

    that explodes the firmware you linked, but it needs a decryption key.

    However the rk3228h should be the 64bit version of the rk3228.

    Cheers

    Hi punter,

    thanks for the logs

    Code
    Feb 02 15:29:48.501460 LibreELEC kernel: mmcblk2: mmc2:0001 M8G2FA 7.45 GiB

    the internal emmc was successfully detected.

    So which tool doesn't work, the multitool?!

    Anyway, you can try to install the build directly from sd card. Copy the desired Libreelec build somewhere in the storage partition of sdcard and do something like this

    Code
    dd if={path_to_image} of=/dev/mmcblk2

    and if you want to make a backup first (which I suggest)

    Code
    dd if=/dev/mmcblk2 of=sample_backup.img

    There is a script to automate everything in my to-do list, but installing Libreelec in internal memory is a procedure for those who know what to do. So I preferred to wait for the builds to become more stable.

    Try and let me known.

    Hello anjarys

    I'm glad you like it. What kind of box do you have!?!

    Anyway, I haven't written a tutorial (yet), but the best tool is the multitool made by jock2 for armbian.

    You can find it here https://forum.armbian.com/topic/12656-cs…k322x-tv-boxes/.

    Basically, it's a small operating system that allows you to backup/restore internal memory and flash images. It works perfectly and you can find the details in the excellent guide by jock2. (clearly the guide is for armbian, but it also applies to libreelec images)

    Let me know if you have any problems.

    Cheers

    other news.

    I'm working on a fork of rkflashtool improving it as much as possible:

    GitHub - ilmich/rkflashtool: Tools for flashing Rockchip devices
    Tools for flashing Rockchip devices. Contribute to ilmich/rkflashtool development by creating an account on GitHub.
    github.com

    The goal is to create a tool (also graphical and for windows) to facilitate flash operations on internal memory (especially nand). The multitool is the best tool, but for those with nand devices, not the most optimal(yet).

    Hi SN33KY

    don't worry, I didn't take it personally.

    But for users reading, you were just unlucky and impatient.

    By the way, in my region (europe) the hardware you mentioned seems out of production and even looking for it used it costs much more than 100€ (and often sold without hard disk and with 16GB of ram).

    Could you please tell me where did you buy the box you returned?! I'm also looking for one with emcp.

    thank you

    Michele

    Hi SN33KY,

    the important thing is that you have satisfied your need, even if I'm sorry because with your contribution I could have fixed something.

    For me, it makes little sense to compare an Android box to a PC (although I prefer boxes because they are silent and consume very little electricity).

    However, in my experience, you pay for what you get. What gets sacrificed to keep costs down with the Android boxes I see around is the quality of the software. For example, Amazon products have an even older soc than rk3229. But the software is of good quality and therefore works.

    My project aims to fill the gap by bringing high quality software (libreelec) to these devices. Unfortunately time, skills, and availability of devices for tests... sometimes makes it difficult to please everyone :)

    hi SN33KY, do you have an A-to-A USB cable!? Do you normally use linux or windows!?

    I recently discovered a problem with the boot and NAND memory (which is not your case) that prevent libreelec from starting correctly (it was necessary to flash an ad-hoc loader afterward). I'm currently on a short vacation and can't share the fix with you. But if you have what I asked you can try to flash a loader using rockchip tools in order to better understand the problem.

    Hi SN33KY,

    thanks for the log.

    Here I see that you are using a 4GB sd card and your internal memory is 8GB (which is the norm for these boxes and probably the seller put in false characteristics).

    Then everything is detected correctly.

    As for the installation via multitool, the procedure is

    - erase the internal memory with the dedicated option

    - flash the image

    did you do it this way?!

    Hi SN33KY,

    you probably have a box that mounts an internal EMCP memory.

    This type of memory differs slightly from the classic emmc (on the board you should see a single chip for internal and ddr memory).

    Unfortunately, I do not have a box of this type, but it would be helpful a log(https://wiki.libreelec.tv/support/log-files) generated starting from the SD card.

    I want to check if it's a detection problem or something else.

    thanks

    Michele
