Hello Tom, Thanks for the reply. I forgot to mention that we are also using the TI/MV kernel version 2.6.10. Is it the same that you are using???
I did check the Datasheets of the processor. It does say that UART2 is multiplexed with CI and CCD ports. These ports are however used for interfacing a CMOS or CCD Image sensor (which we are not using anyways). The CCTV camera is on the YI port which is not multiplexed with anything. Are you too using the CCTV camera in your system in addition to UART2??? If yes then I think there should not be any problem. Also are you using the UART with flow control??? Because in some of the previous posts people had faced problems with flow control. Thanks again in advance for your help.

Is this correct??? At the driver level, I'm not sure; we use the TI/MV kernel rather than the 'git' version. At the hardware level, VPFE and UART2 signals are pin- muxed and therefore *might* conflict, depending on your use. Have you looked at the pin muxing info (ex. table 3-13) in the DM6446 datasheet? > I had gone through (in very fine detail trust me :-) ) the schematics of the > Davinci DVEVM board and found that the YI port is the one that is used for > Video in and the CI port is the one that is multiplexed with UART2.

We use both, yes, so it is possible. But it means that certain VPFE sig- nals are unavailable to us. This is not an issue in our situation, but your situation may be different.
