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

It's still not work.

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.

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.
