Violet screen when using iMX6S + TP2854 + Camera HDTVI

toanjunifer — Thu, 14 May 2020 10:12:06 GMT

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
