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

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:

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

LibreELEC:~ # nano /tmp/config

the config should then look like this:

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

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.

Awesome. Thank you.

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

Hello,

I have the same problem as Tager, LE 11 Kodi v20 Nexus! is there also a solution for this, I have unfortunately found nothing so far!
