None of the images work for me. Kernel boots - blue LED flashes. No HDMI output, Ethernet port is not active. I tested with 2 different SD Cards (16 & 32GB), Etcher and dd. UART output attached. I waited 15 minutes - no further output…
Waited half a year for an emmc capable image ☹
@tom31415 I got the ubuntu-headless to work, but like you said, no networking. Manually enabled DHCP on the interface and was able to access SSH and update, add nano to edit files, etc. The other images yeah... No worky. Trying the android image next.
@tom31415 Try power cycling it a few times. We enabled SDR104 UHS mode and it doesn't like to work with some cards. Another alternative for testing is this:
maybe it's the card that let's it work for me, usaly turning on pc wakes my monitor
from sleep , but with this I have to turn off/on monitor so it searches for signal
and start boot sometimes the short search miss's and after to try again, but if I
use restart board turns off monitor goes to sleep board starts up and wakes monitor
like normal, I started using only sandisk ultra or extreme with A1 rating for app performance for these sbc's,
@jameselis Try power cycling the device. Sometimes it doesn't detect the MicroSD card on boot. This is a known issue and highest priority for us to fix.

a) if the hdmi port is connected to the monitor, there will be no display when booting completes.
b if the hdmi port is disconnected on restart but plugged in when the blue light starts to flash, the monitor will be squashed to only the top half of the screen
c) if the hdmi port is disconnected and power is shutdown, then booted, and when the blue light flashes then plug the monitor in, then display will be normal and everything is fine. _

Suppose problem is image and SD Card upper 8Gb perhaps 16 Gb. The sound play good. Compliment at all : )
@KenDickey Most likely the issue is the unsupported 1366x768 resolution. That resolution needs to be added to the kernel. The Android and LibreELEC images based on Linux 3.14 kernel should support that resolution.
@marcofranchimoretti In the next image, we will disable UHS because it is causing a lot of issues with some SD cards. We will let users enable UHS manually instead.
Got the board to boot with a class 10 micro SD card that has no UHS. As loverpi said UHS is causing problems. No audio yet as far as I can tell but the board boots and can play videos. I got the board to work with the panda wifi adapter you can find on Amazon. The top left USB port gave me problems still. Thanks for the update!
@KenDickey The armbian OS works quite well so far. I even got some audio with a usb to audio device. Thanks!
The armbian for lepotato starts with a terminal where you login as root with password 1234. Then you set up an administrator account to run the desktop.
Seems to work quite nicely at the moment. I'll need to do some testing for stability but with audio I can start the project I was hopping to get running with this board. Thanks to armbian for the software and libre for the board!
Ugh, I have a SanDisk Ultra class 10, A1, all the bells and whistles, I got it specifically for SBC use, hangs just as others are reporting. G.Skill class 10, U1 is the same. Only a G.Skill class 6(!!!) card boots... again, it doesn't matter how fast or low power it is if the $%^#^ thing doesn't work! A coaster uses even less power, but at least I can set my drink on it.
I want to send big greatness at all for good work. I want to ask a questions: aml-s905x-cc-ubuntu-xenial-linux-libretech-4.14.29-libre-computer-desktop-2018-04-10 i don't understand why LED Blue blink every time, someone have explication ? Great work with Sound, i want ask if is possible to active USB audio for external sound, under Armbian is possible. Have not crash here with Firefox, but is real slow and when start, only one core is work: and work a lot. Thanks all.

@tom31415 What MicroSD card are you using?
@loverpi used a SanDisk Ultra sdhc Class10 16 GB
@tom31415 Try power cycling it a few times. We enabled SDR104 UHS mode and it doesn't like to work with some cards. Another alternative for testing is this:

@jeepthing There's a bug with soft reboot that causes UHS to hang. This is a major bug and will be fixed soon.
Hi, I'm not getting a display on the potato board. I attached my uboot log. Not sure what is going on. Thanks!
@jameselis Try power cycling the device. Sometimes it doesn't detect the MicroSD card on boot. This is a known issue and highest priority for us to fix.
@jameselis How do you get that log? Through UART?
@loverpi thanks for the support
@loverpi Hi, I repeated the test with a SanDisk Extreme U3 A1 card. I also entered the u-boot commands - still no successful boot.
@WerBn The Log is from the uart port. Hooked up to the GND tx and rx pins.
@loverpi Would a USB flash drive work to get the device booting?
@jameselis It will boot off the flash drive but we have not made any images yet.
I have copied image for LePatato from loverpi to SD card SunDisk 32Gb( used Etcher ), but board does not come up / does not boot. RED & Yellow LED is always on and BLUE is blinking.
What SD cards have been confirmed to work with this board?

I was able to apt-get update & upgrade, but no display.
Can I do something? (load a kernel module, change /etc/*conf)?
Display is HDMI Samsung @1366x768
Thanks in advance for any help.

@KenDickey I looked in settings/display don't see that resolution listed,
Success!

I have a similar problem, but discovered this:
a) if the hdmi port is connected to the monitor, there will be no display when booting completes.
b if the hdmi port is disconnected on restart but plugged in when the blue light starts to flash, the monitor will be squashed to only the top half of the screen
c) if the hdmi port is disconnected and power is shutdown, then booted, and when the blue light flashes then plug the monitor in, then display will be normal and everything is fine. _
