Hi, Elux
No idea what is wrong. Have same output when HDMI is not conntected. But no rebooting.
Is anything connected into HDMI port? Does it continue rebooting if you connect/disconnect HDMI?
Maybe try another power supply or something...
Which hardware version of Orange PI PC do you have? Mine is v1.3
Are you sure that you not only changed quiet to debugging systemd.debug_shell earlyprintk but also removed console=tty1 at the end of line?
If I do not remove it, I have the same output on the serial port.
Are you sure it is a boot loop, not a single reboot after resizing of partition?
Just a guess but I think it is booting normally, only there is nothing on your display for some reason. And if you remove console=tty1, you will get more info on serial console. Sorry if I am wrong.
Stable LE12 images (12.0.0 and 12.0.1 for sure) will not boot because there was a bug in u-boot configuration for Orange PI PC at the moment they were released
There was a problem booting stable image but it was fixed and recent nightly builds should work fine. I've just tried LibreELEC-H3.arm-12.0-nightly-20241204-f894320-orangepi-pc.img.gz image and it boots. The serial port output is the same as yours.
Try changing quiet console=ttyS0,115200 console=tty1 to debugging systemd.debug_shell earlyprintk console=ttyS0,115200 in /extlinux/extlinux.conf to get more output on serial port.
Do you mean microSD card when you say MMC? To be sure you do not use Orange Pi PC image on Orange Pi PC Plus, which has eMMC, for example
dando Current crust firmware (v0.6) supports NEC, extended NEC and RC6 infrared protocols. So your remote control must be using one of this protocols.
By default it is enabled and built with:
CONFIG_CIR_PROTO_RC6=y
CONFIG_CIR_WAKE_CODE=0x800f040c
It seems that the only way to change these settings is to build LE image (or at least crust and u-boot) from source.
I just tried and it works 
dando, please try recent nightly images. Seems like it is already fixed here: https://github.com/LibreELEC/Libr…08106e62a53fe46
Both 12 and 13 should work but I haven't tested it yet
I checked OrangePi Plus2E, but everything works fine.
Tried plus2e image on my Orange Pi PC and it worked.
After some research it turned out that CONFIG_REMOTEPROC_SUN6I_AR100 in u-boot is enabled for orangepi_plus2e but not for orangepi_pc.
The reason is that in this commit: https://github.com/LibreELEC/Libr…0b9c2db50a03683
projects/Allwinner/patches/u-boot/0012-DO-NOT-MERGE-sunxi-Enable-remoteproc-on-H3.patch
is replaced by
projects/Allwinner/patches/u-boot/0011-DO-NOT-MERGE-sunxi-Enable-remoteproc-on-some-H3-boar.patch
which enables AR100 only for Orange Pi One and Orange Pi Plus2E.
After enabling AR100 for Orange Pi PC, it works fine too.
Tried to find when it was broken. u-boot 2023.10 works OK. Starting from 2024.01 my Orange Pi PC doesn't boot.
When I delete these patches from projects/Allwinner/devices/H3/patches/u-boot/:
0012-DO-NOT-MERGE-sunxi-psci-Delegate-PSCI-to-SCPI.patch
0013-DO-NOT-MERGE-sunxi-Enable-SCP-SCPI-on-A33-as-well.patch
system boots normally but can not be woken up from suspend via on-board button.
