RPi4 + LibreELEC 10.0.1 : Works on 2GB from summer 2019 but not on 4GB RPI?

GarryX3D · November 15, 2021 at 2:04 AM

I have tested to Installd LibreELEC 10.0.1 with different SD-Cards:

LibreELEC 10.0.1 works on RPI4b 2GB von summer 2019 and works not on my new (from last week) RPI4b 4GB -> Screen stays black

Both without changes for config.txt

If I try LibreELEC 9.x both RPI4b are working without problems (No change @ config.txt, same SD-Cards, same cables,...)

If I write

hdmi_force_hotplug=1

hdmi_drive=2

in the config.txt file the screen displays some text (@HDMI0) but stops soon while booting with

Trying partition: 0

lba: 8192 oem ...

"Bad cluster number 0"

Any idea what's going wrong?

Did you test 10.0.0?

A few users (including me) have a blank screen after the update to 10.0.1, but 10.0.0 (even the downgrade from 10.0.1) works. But it's possible that your problem is unrelated, the "bad cluster" error is new to me.

LE 10.0.1 / Rpi4 / No picture after update from LE 10.0.0

Hi,

after the LE 10.0.1 update of my clean installed LE 10.0.0 from the LibreElec menu and a reboot i get no picture anymore. Only the blue screen of my Onkyo AV.

LE 10.0.0 runs fine since 6 Weeks.

Switched to the other HDMI out of the Rpi4.

Completely shutdown and start again the TV, AV Receiver and the RPi4.

Nothing special added in my config.txt.

Tried to add in cmdline.txt:

video=HDMI-A-1:1920x1080M@60

I can still reach Kodi via SSH and the Android Yatse app. Playing media, controlling CEC via TV…

Compare the HW revisions of RPi 4B/2GB and RPi 4B/4GB, also check / compare the bootloader versions and bootloader configs. Without any details shared it's hard to say what the root of the issue is.

So it looks like the firmware problem - thanks zehner for the link!

Is just a firmware downgrade usefull possible with rpi-eeprom-update?

Firmware (not VL805 USB controller's firmware) is located on filesystem so in case of LE it depends on LE version. You can't change the firmware release with rpi-eeprom-update utility. To change the firmware version you need to replace the specific files (see https://github.com/raspberrypi/firmware ) on appropriate partition. You should avoid this as it's usually not necessary, rather install another LE version. I don't know which firmware version is on LE 10.0.1 as I am running LE 11 Nightlies (https://test.libreelec.tv/).

Bootloader on RPi 4B is located in EEPROM, also the bootloader configuration. I would not try to downgrade the bootloader version, at first compare the bootloader configs as recommended above (use vcgencmd bootloader_config command). The latest stable bootloader version is 2021-07-06 (see https://github.com/raspberrypi/rp…irmware/stable/) and I would recommend upgrading to latest. Also VL805 firmware should be 000138a1. See this post for detailed steps how to upgrade manually: RE: Is it possible already to set up a rpi4 with kernel 5.4?
