Forum Post: Activating color bars on DM355 TVOUT from reset state

What registers do I need to set to activate the color test bars on TVOUT pin?

I was able to do it under Linux as most of TVOUT is initialized in the drivers. However, it is a challenge to trace all of the registers throughout multiple documents to implement color bars from scratch in UBL.

The processor has a single 24MHZ crystal.

PLL Frequency = 270MHz. 

PLLDIV3 is set to /10 to get 27MHz.

I have tried the following without success:

SYSTEM->VPSS_CLKCTL = 0x018;
*((VUint32*)0x01C70004) |= 0x05;
VENC->CLKCTL = 0x01;
VENC->VMOD = 0;
VENC->VMOD = 0x03;
VENC->DACTST = 0;
VENC->VDPRO = 0x100;

Edited:

Looking at the composite signal on TVOUT, I'm getting a flat line.
