I changed file extlinux.conf:Code
And get the same error where "/dev/mmcblk0p1" is written instead of "LABEL=LIBREELEC".
I can say with certainty that older the official nightly builds of LE10 worked on my C2 (the only thing that worked slowly was the KODI interface). And then in the last nightly official builds of LE10 I got this error. This error is apparently due to the fact that support has been added for booting from a USB flash drive. I have not tried to write to a USB flash drive your builds, but I tried to write a USB flash drive on the latest official night builds of LE10 - if a microsd card is inserted, which also contains the LE10 build and a flash drive, then Odroid C2 is loaded from the USB flash drive. I can try it on your build and I'm sure it will work. But I want to use only a microsd card.
I have another idea. But I think that it will not give anything. Install the official LE9 on the microsd card, run it to create a full size STORAGE. And then replace on it all the contents (files) of the LIBREELEC section from your LE10 build.Don't work, when you turn on the odroid C2, the blue LED is constantly on and nothing else.
Is it possible from your side to write step-by-step commands to start loading LE10 using the connected keyboard to the Odroid C2, when such an error appears?
I tried to write the microsd card via Creator LibreELEC USB-SD, balenaEtcher in windows 10. And even started opensuse in live mode and writing the microsd card via dd (I previously unpacked img from img.gz). And I still get the same error.
Could you do 2 things for me ?:
1. View the revision of the release on the board odroid c2.
2. Via Gparted, reduce section STORAGE on your microsd card (if you have a large microsd card) and make a full dump microsd card via dd and upload img dump to some file hosting (yandex, google disk or another).
I've only successfully booted my Minix U1 using Samsung EVO sdcard, check attached image. The other sdcards just simply won't boot.
