Sundar, I am developing an application with the same display type and have experienced the same issue. What you are seeing is the result of Bus Priority Inversion (detailed in the usage notes paragraph 2.1 of TMS320DM6446 DMSoC Silicon Errata http://focus.ti.com/lit/er/sprz241e/sprz241e.pdf).
Changing the PBBPR as recommended resolved the issue.

The DCLK requires a frequency of 65 Mhz for this particular LCD as a result of which i am supplying the VPBE clock to the VPBECLK pin. However, any image that is displayed gives me a flickering effect. The same application runs fine when the same LCD is configured through the internal clock at 54 MHz. I would like to know if this effect is a limitation of the Chip itlself or am i missing something anywhere?
