Could it be the power supply?
Unlikely since you tried three of them. Cleaning the slot doesn't mean you can rule it out.
I suggest two options:
a) replace the card reader
b) use a JTAG for searching other issues
If you're convinced it's not the the card reader, take option b).
To my knowledge RPi can't output real interlaced video. I just don't see why this should matter. We have a couple of RPi users, who run CRT TV's successfully with such fake interlaced modes. This definitely works. Just make sure you run the right LE version (see above).
Card reader contacts can get some oxidation over the years. Try to clean it, or if you have the skills, replace it.
If it doesn't write any log info, then I bet on a broken microSD reader.
Remove the microSD after boot fault, connect it to a desktop PC, and check the log file (if any log exists).
Did that RPi2 ever worked with any software? Try Raspberry Pi OS to check the hardware.
Not LE specific anymore, so I move the thread to Off-Topic.
rsync -a --delete <source_folder> <target_folder>
rsync should be available as network tools add-on.
Cron-job that.
Yeah, this is rare stuff. There is a composite bug in LE 10.0.2, so I think that's the whole reason of the issue.
Generally it should be possible to run 480i by those settings: Click!
Please try a current nightly build: Click!
I've already tested OSMC and Raspiberry OS and both are the same. They only work on HDMI 1, no signal on HDMI0.
Now it's clearly a broken HDMI-0. Use your warranty, or order a replacement.
If you can't do both, then there are other ways to make an RC work, but not as easy as CEC.
I installed Adafruit_DHT as addon. How can I use pip3 on my libreelec10?
You are correct with:
import sys
sys.path.append('/storage/.kodi/addons/virtual.adafruit-libraries/lib')
import Adafruit_DHTYou get the error, because you try to run the Python 2 version of Adafruit DHT:
ImportError: libpython2.7.so.1.0: cannot open shared object file: No such file or directoryUse "pip3" instead of "pip" to download the Python 3 version: pip3 install Adafruit_DHT
Replace the line
import Adafruit_DHTby
sys.path.append('/storage/.kodi/addons/virtual.adafruit-libraries/lib')Create a key mapping file for your RC (/storage/.kodi/userdata/keymaps/remote.xml).
So you can use RC color buttons as replacement for keyboard keys. Details: Click!
LE supports OpenGLES hardware rendering on RPi4. For example it is used for GUI elements.
If your add-on can't deal with it, it's probably not yet implemented, and fallback to software rendering is intended.
Ask the add-on developer for details. Usually add-on developers can be found at Kodi forums, but not here.
