CEC problem with S905 device

    Hello,

    I have a Beelink MINI MX III (S905) device. And I have problem with CEC. I disabled the CEC adapter from System configuration.

    I have 2 problems:

    1. When I power on the device, it power on the TV too. I don't want to power on the TV, because I use to reboot remotely the device at night.

    2. When the TV is off and the device on. If I push the TV POWER key on the TV remote to power on the TV, the device goes power off.

    I have others S905X and I have not any problem with this, I disable the CEC adapter on the all other device and they work well.

    Could I share any log or debug information to the developers to fix it?

    Thanks for your great work.

    Kind regards.

    If you have Android on internal memory, boot to Android and disable CEC there.

    If you don't, try using this command: fw_setenv cecconfig cec0

    Thaks kszaq!

    I don't have Android on internal.

    I try fw_setenv cecconfig cec0 and it works!

    Is this a disable command? How could I enable again? Could I have a complete command list for fw_setenv?

    Best regards.

    fw_setenv is a command to manipulate bootloader env variables, there is no "list" of commands. If you want to see what values are stored, use fw_printenv.

    fw_setenv cecconfig cec0 disables CEC in bootloader and in Android. IIRC it doesn't modify CEC behaviour in LibreELEC.

    To turn it back on, use fw_setenv cecconfig cec17.

    You can also reset all u-boot env variables to their default values by running fw_setenv upgrade_step 1 - this is an Amlogic-specific command, it will also disable booting from SD and USB for devices without native dual-boot.
