2)Make the bootable pendrive using this image.

3)Connect serial cabel Minnowboard Turbot board to host machine ( Any linux machine )

4)Boot the Minnowboard Turbot board using bootable pendrive.

5)host machine check in /dev/ which device name serial connected.
  ( default is coming on ttyUSB0 )

6)Using sudo -s minicom setup the serial connection.

For genericx86 we should not be assuming "minnowisms", regardless of whether its hddimg or wic.
Comment 2 yeoh ee peng 2018-05-10 01:36:29 UTC 
Please try this on a NUC to check.
Comment 3 pravin 2018-06-22 09:00:58 UTC 
this issue is still reproducible on the ycoto build 2.6 M1 rc1 on Minnowboard Turbot.
Comment 4 Anuj Mittal 2018-07-10 03:15:06 UTC 
Looks like a problem with your minicom configuration. I tried using 'screen /dev/ttyUSB0 115200' and I don't see any problem.

Please re-open if you can reproduce using screen.

In Yocto 2.6 M2 rc1 release this issue is not reproducible.
I have tested on MinnowMtourbot board.
