Remote power trouble

  • this is log of another u-boot (from beelink official firmware for GT1 Ultimate)


    this version con pass ram check at: DDR4 chl: Rank0+1 @ 912MHz - PASS


    Btw also this uboot version has the power on bug on H96 pro +

  • please also test this uboot from the other github

    u-boot

    this u-boot can boot:


    but the power on bug is present:

    i've libreelec booted, turn off my board with remote and the system log this:


    after that i cannot power on with remote

  • 1. Therefore, you should test the two versions and not search other forums. So it is very difficult to help someone. uboot gt1 does not support * 3g.dtb, the manufacturer did not integrate it for whatever reason

    Code
    1. Find match dtb: 0

    for * 3g.dtb support there should be a "1" in the place

    2. this uboot does not contain a custom suspend FW and there seems to be a problem with the size calculation. It should only serve for testing to locate the bug.

    The bug is localized, we just have to figure out the most suitable frequency rate. Wait for the update.

    Maybe i dont understand it right. I boot with my normal LE sdcard, write zero to /dev/env and /dev/bootloader and than i insert the Emergency System and write the new boot loader?


    Did i forget something, because if i power off without a bootloader, the system doesnt boot? Or should it boot from SDCard2? Because in my case, it didnt work and i had to restore via USB Burning tool

    Correctly

    it should boot from the sdcard2. Please note - the bootloader in the installation guide is only suitable for devices with LPDDR3 memory (blue pcb v5 and v6).

  • I have flashed this u-boot via Android ROM customization method:

    This time - there was no need to revive the box by short-circuiting certain pins on the eMMc... :)

    However,

    LE still cannot power up from the remote, once it has been powered down.


    How can I gather any serial debug information for eventual troubleshooting further?


    Thank you in advance! :thumbup:


    P.S. I am using gxm_q200_3g.dtb on my green v2.2 board...

    I have the blue one S32-V6 (LPDDR3).


    I will try it again later. Maybe the second SD card is broken.

  • There are two reasons for this. 1. The remote control code does not match the code in the bootloader. 2. Your power supply is poor quality or slightly weak.


    So you can tell if the power supply is not ok.

    - Pull out the HDMI cable on the box.

    - Turn on the box and wait until it has completely booted.

    - Then switch off the box by remote control again.

    - After switching off, try switching the box on by remote control.

    When the box starts up, it's up to the bad power supply.


    Please post your remote.conf file

  • There's new development on my case:


    With this build - CoreELEC-S912.arm-9.0-devel-1523265719 - the box works FLAWLESSLY!


    Therefore,

    here's a link to an amended Android ROM (Wisdom), in which the fixed [email protected] has been already incorporated and it's been tested on green v2.2 H96Pro+ board:


    S912_H96_3G_DDR34_171120_MAC_ubootfix.7z


    Flash the ROM via USB Burning Tool v2.1.2 or Burn Card Maker v2.0.3 on your own risk, of course. :P


    Good luck! :thumbup:


    Thank you, @bumerc !

  • This is no place to comment the "subtitle stutter" issue,

    do not smudge the thread, please.

  • @ChimeyJimmey

    I just pointed out that it does not work FLAWLESSLY! so don't panic, and in future explain WHAT works FLAWLESSLY!
    And I will delete my post, not to smudge the thread :)

  • I would not recommend trying the abovementioned ROM on LPDDR3.

    Apparently the u-boot here is for normal DDR3,

    and there is an enourmous chance to brick the box if you flash it on LPDDR3 one.
