Just need to change uEnv.txt (replacing quiet parameter), reinstall, capture log.

Yes, I have a same problem. If you don't have revision 1.3 I have one solution. One possibility is that I know send to you my HW (matrix pc revision 1.3) for investigation of mentioned issue.

Hi vpeter!

I installed OpenELEC 5.0.0. again with modified uenv.txt.
The result has been mounted on page 14.
In Install and start v2.zip.

In start script not double start log.
After first "Starting kernel..." message restart boot sequence.
Write
"U-Boot 2013.10-rc4 (Dec 29 2014 - 11:02:47)

CPU: Freescale i.MX6Q rev1.2 at 792 MHz"... messages again.

After second "Starting kernel..." message TBS2910 freeze.

No keyboard, no mouse, no UART communication.
Only the Samba shared folders available.

Hi vpeter!

In booting process TBS2910 the TV screen also displays a log.
How can I capture the logs from TV? (Or redirect to serial port?)

Thanks bzoli72

Instead of quiet must be progress debugging console=ttymxc0,115200 - I forgot on console part before. With this 3 parameters we get kernel boot messages shown on console. Sorry for inconvenience.
