Ok noted. So even after a full power cycle, which means switch off the power adapter for 2min (time capacitors discharge) and switch back on, still don't make the board output anything on serial port ?

Based your suggestion and after I am in desperation ...

I turn off the machine, remove the cooler and CPU from socket, let them couple hours on my table.

I reassemble the machine... Turn on...  Tadaa... The machine live and heartbeat again... Serial port connect again.

Thank guys

@rifanoz when is the issue appeared ?

 

FYI the boards go through a FAT (Factory Acceptance Test) before being sent out. Which means each board had a test run with all interfaces tested. So I guess the issue didn't appear on day one ?

I receive the machine at Mar 23, 2018. Then I keep it on warehouse.

Yesterday I tried install it. I try to use Debian and Ubuntu, It's work and serial console too. But I have network problem. I can not set IP Address and access via ssh.

So, I write image again on new sd-card and reset machine via U16 push button.

I turn on machine again then the problem is appeared. I replace with the old sd-card, It still not work.

So... What must I do? Please help.

@rifanoz as Igor suggested please post here the console output.

 

Which image did you write on the sd card ? Have you followed the install instruction ? (https://wiki.kobol.io/install/)

I use the latest OS Images

Debian 9 - Stretch (by Armbian) Build date : 04/07/2018) ... not work.

Ubuntu 18.04 - Bionic (by Armbian) Build date : 04/07/2018 ... not work.

I could if it booted at very least without any HDD connected, but since pretty much right after the various tests and a couple more tries with booting with/without a drive attached yesterday evening (CET) it unfortunately does not even so: no heartbeat, no boot, no logs generated (I double checked) once mains is connected.

I have same problems. no heartbeat, no boot. see my picture Helios4

Please help me.
