Porterdon - I've just installed the 154 image on an 8 GB SD card and working fine here.

Maybe your image was corrupted? Try downloading it again?

I've done that many times, but did again. Same. No boot.

Solved: Dead after: pacman -Suy, included Firmware Update

Hi Forum,

i updated yesterday my Arch Linux it included a Firmware update, and after the reboot i get no Display Output, only glowing red and blinking blue led.
Any chance to get it back running?

pacman.log:
...
[2015-06-04 22:45] [ALPM] upgraded linux-firmware (20150206.17657c3-1 -> 20150511.8e18132-1)

I also thought in the same direction as Ricardona.
It is indeed hard to figure out what your problem is from what you gave away.

A blinking blue LED, IMHO does mean it has indeed booted and the kernel is up an running.
Maybe you don't have any UI and no network (to ssh into it)?
Do you have a UART adapter available?

...I did an update on my ALARM C1 box only yesterday and all is fine after reboot (no X installed, only plain ALARM).
If you happen to have no network....any traces from your router's side?

Thank you Ricardona,

Blinking blue LED == running OS, i tried it again.
It was the same Problem! my monitor was not that nice to say out of sync. Only with a different one i was able to run at 720p with dvi.
The root cause was a glitch in the router, he gave me no ip, but worked again after a reboot.

--------------------------------------

I'll be looking into this....

Have you tried to upgrade dietpi and the kernel?
if I reinstall it, it's working as well, but I won't reinstall it, because of my apps and settings I have to reinstall as well == to much work.

Yes upgraded to v 158 and did kernel upgrade to the latest in the 3 series - worked fine. Why not try this on a spare SD card?

Which kernel were you hoping to upgrade to - the 3 series or 4.9?

John, I'm not fussy. Any kernel which will actually allow me to BOOT!

OK, I downloaded V154 and tried to boot, lights happily(?) flashing away like it was Christmas -- red, blue, yellow ethernet but no booting into 'Joy to the World'. No monitor display. Nothing. Nada, zip, nichts, rien, niente, and in Thai: ไม่มีอะไร.

Pulled out the SD and went into config and uncommented to set:

hdmi_safe=1
hdmi_force_hotplug=1 (not clear if I needed to do this)
config_hdmi_boost=4 (sure, why not?)
(didn't touch the HDMI modes, as if I had a clue)

Then went into boot, uncommented to set:

setenv vout "hdmi"


Then I pulled out the SD, inserted it into the XU4, plugged in the HDMI and power jack.... crossed fingers ..... and ..... Ta Daa! ;-)

:? :shock: :evil:

... SPLAT!

Dear Mr. Hardkernel:

I'll be taking a few days off. Need a little break out of town... in Raspberry Pi land.

Please carry on. :geek:

Yours faithfully,

Don

P.S. Please send money. $36 would be perfect. 8-)

If it doesn't boot with a freshly flashed SD card then maybe the XU4 has a fault? Or inadequate power supply? Faulty SD?

Have you tried installing anothter distro?

Like I stated in my initial post -> 3.1.106+ on version 157.
And like I said before - The problem is gone if I reinstall my whole system, but this is no option now (until I really have to, if there's no fix available)

The fixes PorterDon recommends don't work - I still don't get any signal out of it to give you some more information (If there'd be some kind of bootlog I'd be so glad to share it with you to get this thing fixed)

The powersupply works, it's the official powersupply of the cloudshell 2 which worked until I rebooted it and if I use another SD-Card or even the same card (made a clone before and reinstalled the system on that same card) it's working normally and I can connect via SSH.
So the SD-Card, the power supply, the network or the XU4 itself is not the issue.

Can you post your boot.ini and is there something in your /rootfs/Dietpi folder? Can you just make an image of your working SD-Card so I can compare the differences? That would be really nice and I'm posting the issue on github if I find the rootcause.

EDIT: Hell I even make a video now to show you what's going on:

The Solution:

The firmware file exynos-blabla.dtb was simply missing!
I installed dietpi again on another card copied that file into the boot directory of the other card and it's booting!

Maybe the uboot or kernel upgrade removed the old xu3.dtb file but didn't install the new xu4.dtb file.
