Ach.... I do see.

I think that BIG FAT note in the installation page that python 3.6+ is
required would be helpful here (maybe I'm a bit old-fashion, but I only
distinct two python versions - 2.x and 3.x :-) ).

Ok.

Just one note - debian9 (stable) only supports 3.5.x python, so we are
a bit cutting edge with tbot now...

I do want to use BBB as a manager of the tbot "LAB" - in a sense as
Heiko did in the past. 

The setup would be as follows:

- IP power cord
- IMX6Q DUT
- 24V power supply

- BBB (it would control the power strip - via eth and it I would
  have the serial <-> usb converter connected to DUT). It would be
  responsible for "local" management. I would have a separate build
  machine (with Jenkins or buildbot) to provide u-boot/kernel.

  Why BBB? Small, cheap, silent.

Yes, it will execute the tests (maybe with buildbot visualization - if
possible)

Or is there any better way to visualise results from local run of tests?
(And on the beginning I would like to test if u-boot is build and runs
on the board as well as kernel boots till prompt).
