The finger usually points to SD cards as a last resort.
In the past I really had SD cards which caused issues in U-Boot. But in such cases, boot breaks early on. Thankfully, such issues are rare.

As best as I can tell, the LE USB SD creator does the following:
Partitions the SD card properly (512 MB FAT (Active partition), 32 MB Fat (swap space), 14.2 GB Unallocated.Writes the contents of the "OS" onto the Active partition
Do you do anything else when you prepare a SD?No, that's all.
I saw the nice words you said about the Orange Pi 3 LTS (as well as some other folks), and went ahead and got one (after a minor detour to a Chinese mini-pc that had a few things wrong)....
Mine works pretty well, minus occasional boot hiccup, but reboot mitigate it. Thing is that OrangePi 3 LTS support is pretty new and I'm working on solving all kinks. Your issue is pretty unique and hard to solve since I can't reproduce it.
Is there any "easy" way to set up the serial adapter to do the debugging? I'm not sure what you mean ...
You have to have it first. Check ebay under "uart adapter". Alternatively, you can use some other SBC with 3.3 V UART lines.
I found another possible explanation. Replace sun50i-h6-orangepi-3-lts.dtb with this one: http://jernej.libreelec.tv/tmp/sun50i-h6-orangepi-3-lts.dtb This will lower max. possible SD card speed, which has more chances to work.

I actually don't know anything about LE USB SD creator. I always unpack images and write them with dd to SD card under Linux. In any case, image is booting, so it's written correctly.
I just retested above image on fresh SD card and it works fine, so there must be some difference. Can you test some other SD card? What kind of SD card are you using?
Another thing to try would be removing quiet console=ttyS0,115200 from extlinux.conf. This should produce additional messages on screen.EDIT: For some reason, this still doesn't print all messages on screen. From this point on, it's only possible to debug using serial adapter...

spschneer Please test image from here: http://jernej.libreelec.tv/test/opi3-lts/ If it doesn't work, please follow above request with removing quiet

Sorry, I just realized that this fails early in boot, where there is no network drivers to load. For reference, you almost correctly edited extlinux.conf, just replace comma with space.
I suppose you don't have serial adapter? That would certainly make it easier to access system even in such state.
However, there is one possibility. Remove quiet from APPEND line in extlinux.conf. It should print much more info, hopefully also error messages. In the mean time, I'll take a look at schematic.

Can you try to boot it several times? I saw such message only when I was developing support for it, but not with the latest images. Also, dmesg output would be nice. You can add ssh at the end of extlinux.conf argument list, which will enable ssh.
chewitt this is most likely issue with power settings on PMIC.

There is no OrangePi 3 LTS support in LE10. LE11 beta2 should be already pretty stable.
-
Execute install2emmc command from ssh. Be warned, all content on eMMC will be gone, without any backup.
-
frakkin64 you're right, thanks for that info.
deleonkikko please test image or update from here: http://jernej.libreelec.tv/test/opi3-lts/ your archer wifi should work.
-
offbeat can you provide first 50 MiB (zipped) of your eMMC, assuming Android is still there ? I'm trying to find out which regulator is causing issues and set it properly in DT, so this ATF hack won't be needed anymore.

RTL8812BU
ah, yes, RTL8822BU would work, but not RTL8812BU...
deleonkikko bad luck, try another wifi dongle.
-
This is not good enough. Driver should work and we need to find the issue. Plug in your wifi dongle, enable ssh in settings, connect to the board via ssh and execute following commands:
Codelsusb dmesgOnce you done that, copy and paste that output to pastebin.com and create a link which you paste it here.
-
Please provide output of lsusb so I can take a look which driver is needed.
-
No, we only support wifi chips which are supported by mainline kernel.
-
It appears to have everything (including wifi)
wifi is not and most likely won't be supported by LE.
-
Yes, it's already in master and it will be in LE11 beta2.
-
Please try tomorrow nightly image. I can't do more than that.
-
I prepared new test image here: http://jernej.libreelec.tv/test/opi3-lts/
Please test it and report if network works more reliable. I'll prepare PR in the meantime.
