Colibri VF50 UART0 stalls after sometime

UART0/Debug Serial port stalls .After sometime nothing gets displayed.
Although the board appears to be running OK.

Can you also provide information related to the OS you are using and version of the same ?

Linux version 4.4.21

Seems you are using older Linux image, can you please use our latest Linux image and check. It will be very much helpful if you can provide us some boot logs. May I also know your setup(both h/w and s/w)?
