DS90ub940 internal Pattern generation

Hi, e2e,

I am trying to use 940 internal pattern, from http://www.ti.com/lit/an/snla132c/snla132c.pdf, at 800x480@61.4Hz by default.

i setup 940:

  reg0x01 = 0x06;  // reset

  reg0x65 = 0x04;  // using its "own video timing"

  reg0x64 = 0x05;  // using "Color bars enabled" and then enable PATGEN.

Then, my iMX6 seems get clock, but it is failed to get Frame Start or Frame End.

Is something I setup for pattern output wrong?

Thanks,

Dennis
