We have a customized board based DM6467EVM, the only change is the output video encoder which is TW2880. We can correctly setup video port for display in emulator mode using CSS IDE, but when move the same code and compiled in ARM Linux, it doesn't work anymore. there is no video output from TW2880 port, what is the correct steps to setup the video port for display? In CCS mode, since there is no OS, we need setup PLL0, PLL1, in which PLL1 for DDR RAM, PLL0 for CPU, pinMUX, finally the video port parameters etc, My assumption in Linux: we only need to setup the video port parameters, assume that Linux OS takes care of other system parameters, is this correct? IF this is true, why I am not getting video output from display port? Please help! Jim
