RPi4. USB-ports does not turn-off power after shutdown.

1st Official Post

    LibreElec 9.1.501 and Raspberry Pi 4B

    After power-off through the main menu - Shutdown, USB-HDD continue to work. The USB continues to receive voltage.

    On Raspberry Pi3B and Pi3B+ USB-disks were turned off completely, power to USB was not received.

    I noticed this the other day, but with Raspbian, not LibreELEC specifically. I'm pretty sure it's a raspberry pi 4 firmware thing that's been implemented recently, as I have a Noctua NF-A6x25 5V fan mounted over top of the heatsinks, powered through one of the USB 2.0 ports, and up until a few days ago, I could tell the Pi had completely powered down when the fan stopped spinning. Now, it just keeps spinning. That, and the network port is blinking now as well.

    Yes, this is the default behaviour in current RPi4 bootloader firmware. You can change that by editing the bootloader config settings.

    On LibreELEC 9.2 Beta 2 (9.1.502) first run the following command to get the default config:

    Code
    LibreELEC:~ # rpi-eeprom-config --out /tmp/config /lib/firmware/raspberrypi/bootloader/critical/pieeprom-2019-09-10.bin

    Then edit the /tmp/config file and change POWER_OFF_ON_HALT to 1 and WAKE_ON_GPIO to 0.

    eg run

    Code
    LibreELEC:~ # nano /tmp/config

    the config should then look like this:

    Code
    BOOT_UART=0
WAKE_ON_GPIO=0
POWER_OFF_ON_HALT=1
FREEZE_VERSION=0

    Then create a bootloader firmware file with the changed config and install it

    Code
    LibreELEC:~ # rpi-eeprom-config /lib/firmware/raspberrypi/bootloader/critical/pieeprom-2019-09-10.bin --config /tmp/config --out /tmp/pieeprom
LibreELEC:~ # rpi-eeprom-update -d -f /tmp/pieeprom

    Now reboot to update the bootloader eeprom.

    You can check if the update was successful by running vcgencmd bootloader_version (it should report Sep 10 2019) and vcgencmd bootloader_config (it should print the config from above).

    Note: you only have to do this once, subsequent bootloader updates (via the LE settings addon) will keep config in the bootloader eeprom intact.

    so long,

    Hi,

    After updating the bootloader firmwareI noticed the same behaviour as described by TAGER.

    I followed the procedure to revert back to Sep 10 2019 firmware with these option

    1. WAKE_ON_GPIO=0
    2. POWER_OFF_ON_HALT=1

    Everything is now ok, but i wonder if it's safe and possible to generate a bootloader firmware with the same options using the latest firmware so it would be possible to have a full shutdown (no spinning usb drives) and benefits from the new advantages of the latest firmware ?

    thanks

    Sep 10 is still the latest official firmware. If you want to use / test the beta firmware you have to download it manually from here rpi-eeprom/firmware/beta at master · raspberrypi/rpi-eeprom · GitHub

    You can use rpi-eeprom-config / rpi-eeprom update as outlined above - at your own risk, as usual for beta stuff.

    I've been using the beta firmwares for a while now (mainly to test network booting) and in general they worked quite well.

    so long,

    Hias
