Ubuntu Minimal 18.04.1 no boot on XU3(SOLVED)

Unread post by xblackdemonx » Sat Apr 06, 2019 3:52 am

I installed ubuntu-18.04.1-4.14-minimal-odroid-xu4-20181203.img on my XU3 and it's not booting at all.
I see the red and blue light flash quickly and I also see the ethernet lights flashing but the screen stays black.
I also see the fan turning from time to times.

I tried to flash the microSD multiple times but it never boots.


If I use the same SD card but with ubuntu-16.04-minimal-odroid-xu3-20170727.img it boots no problem but I cannot use RetroPie since the OS is not recent enough.

please help.
EDIT: I took the files from the boot partition of ubuntu-16.04-minimal-odroid-xu3-20170727.img and copied them over the boot partition of ubuntu-18.04.1-4.14-minimal-odroid-xu4-20181203.img and now it works. It seems like the files of the boot partition ubuntu-18.04.1-4.14-minimal-odroid-xu4-20181203.img are broken for XU3. please fix Odroid

EDIT2: By doing this I broke the network.

The first thing I would try is downloading the Ubuntu 18.04 image a second time and re-imaging the SD card with the new copy. You might have a corrupted download.

How are you copying the image to the SD card? The officially supported way is to use Etcher to flash the image. While it can work other ways none of those ways are officially supported.

If the problem still occurs after trying a fresh download and flashing with Etcher please let us know.

Yes, it is worth to check the md5sum value.

If your XU3 board has an issue of the Board-ID detection, edit boot.ini file to force XU3 mode.
Remove line 173~177.
https://github.com/mdrjr/5422_bootini/b ... #L173-L177
And add fatload mmc 0:1 0x44000000 exynos5422-odroidxu3.dtb

I tried to take the boot.ini from 16.04 and copy it over the boot.ini of 18.04 and I still have a black screen even though I see the blue and red LED flashing and the ethernet LEDs are also flashing. I know it's running even though I don't have a display.

The screen stays black like if there is no signal.

Blue+red+ethernet leds are still flashing. The fan is spinning.

I am unable to get a display...

I tried to flash the image like 30 times already with both Win32DiskImager and Etcher and I always end up with the same result.

My screen supports 1080P so that shouldn't be an issue. Like I said in OP, If I flash the 16.04 LTS image it boots right away, no problems I can see the screen and everything. It's only with the 18.04 LTS image that I get no display.

what type and sizeof sd-card are you using

The RootFS Auto-resize feature has changed!!!
Once everything is done after auto-resize, the power will turn off automatically. Wait a couple of minutes.
And unplug-plug the DC plug when the blue LED is off. then plug it back again

are you doing this or does it just sit there spinning on you initial power up

Yes, when I first boot the device I see the blue led flashing very quickly like if it's resizing. I wait until it shuts down (ethernet leds off, blue led off, red led on).
Then I unplug it and plug it back in. Black screen with the blue led flashing like a hard drive.
