RPi3 Updade to 9.2.3 ending in Black Screen

Can you please test the following things:

- does the RPi boot with 9.2.3 (after the reboot hang) if you disconnect and reconnect power?

- do LE 9.2.1 and 9.2.0 show the same behaviour? LibreELEC-RPi2.arm-9.2.1.img.gz LibreELEC-RPi2.arm-9.2.0.img.gz

- have you tested with a different SD card?

If 9.0.2 works can you please ssh in and post the output of journalctl -a | pastebinit

so long,

Hias

please do the tests with 9.2.1 and 9.2.0 and run the journalctl command on 9.0.2.

so long,

Hias

Thanks for testing!

Could you replace the firmware files on the /flash / FAT partition of a LE 9.2.3 installation with the ones from this ZIP rpi-firmware-9e3c23c.zip and test if it boots now?

so long,

Hias

Thanks for confirming!

This is very likely a bug in the firmware, the one in the zip is from Apr 15, before RP0-3 and RPi4 firmwares were merged. I've pinged the Raspberry Pi devs.

Could you install 9.2.3 again (to get the latest firmware) and then try to add one of the following lines to config.txt (only try one setting at a time) and check if that lets your RPi boot:

• over_voltage=2
• core_freq=250
• force_turbo=1

Have been trying to troubleshoot this exact problem for a bit now and found this thread as I am looking at trying out Kodi.

I have got it successfully booting by replacing the firmware files with those suggested.

I also tried doing a fresh image and then updating config.txt with the following: core_freq=250 which the OP said allowed it to boot, however it then wouldn't boot for me. I'm not sure if I put the line in the wrong spot or if it requires any special spacing.

With the replaced firmware files at least I can now boot and setup Kodi.

Thanks a lot for reporting the issue!

If you are not sure about config.txt just attach it here and I'll have a look

In general I add settings at the end of config.txt as that makes sure they override any previous settings.

BTW: it could be that one of the other config.txt settings I mentioned helps with your RPi, please test those, too (try only one of them at a time).

And please tell us which RPi you are using (2B, 3B, 3B+) and post a logfile of LE 9.2.3 running with the replaced firmware files. Go to Settings -> LibreELEC -> System and select "Upload latest Kodi log and configs, and view the short URL", then post the URL you got.

I am testing LE 9.2.3 with firmware from post 9 on rpi 3B+ from USB stick/boot.

I am under-clock minimum freq...

The only problem is that for some strange reason after 1-2 days I get throttled and this with a power adapter 5v/3.1A that work perfect on rpi 4B - 2G RAM ( no throttled ).

Next week will test with another new power adapter 5v/3A and another USB stick.

p.s.

bo ost it is censored ?!

WARNING:  You are being throttled.  This is likely because you are undervoltage.  Please connect your PI to a better power supply!

throttled= 0x80000 means that the RPi3B+ went over the soft temperature limit of 60°C and throttled the CPU down from 1400 to 1200MHz at some time in the past. Your power supply is fine.

Don't worry too much about core_freq or the other config.txt changes mentioned in this thread not working, these were suggested as a test by a RPi engineer and it seems they don't help in most cases.

Just replace the firmware files on LE 9.2.3 with the ones from the zip and you should be fine.
