Does CE 2.21 Support DM6446?

Yes.  The release notes include a "Device Support" section:

Hi, Chris

AYK, CE2.21 support DM6446.

But the LSP 2.00 cannot support the demos very well.

I've ported everything from dvsdk on to it. DSPLink, CMem, CodedecEnging, etc.

But when I try to run the demo, Cmem loading is ok, DSPlink loading is ok.         but when run interface, system crashed.

I just printfed some infomation and found it crashed when call FBIOPUT_VSCREENINFO. No followed msgs printfed. As the Black an Italy line shows below.

Could you please give me any Idea about this.

It may be easy to get past this error (frame buffer driver ioctls are pretty standardized); I believe there are a couple of ioctls that tell you the driver capabilities underneath, which should serve as good reference to know what parameters you can pass via FBIOPUT_VSCREEINFO ioctl.  As a last resort, we can always add printks to driver code to get additional information as to why this ioctl is failing. 

What concerns me most is that you are dealing with LSP 2.0 and new CE, CMEM and DSPLINK.   Not that it should not work, but it seems like a pretty large effort to undertake as the examples and demos in current DVSDK where not designed with these newer components in mind.  There will be newer DVSDK coming out soon that should incorporrate LSP 2.0 as well as newer codec engine, dsplink and cmem.
