Hi,

I'm trying to use Camera HDTVI with TP2854 in iMX6S(Linux 4.1.15). After try some example program in unit_test folder, such as: 

   $ ./mxc_v4l2_tvin.out -ol 0 -ot 0 -ow 960 -oh 540 -d 1 -x 0 & sleep 10

I get only violet screen:

Someone can tell me why does it happened ? And how to fix it ?

Thank you so much,

Toan
