We are writing small application on TI's DM6446 evaluation board.
I am facing sound related problem i.e., with /dev/dsp.

Hi
How can I use CMEM and all it's API. In my application. I need to get one
buffer with size almost 10MB, which will be continous in virtual and
physical memory space. I have tried link cmem.a to my project but it told me
undefined reference to CMEM_init and so on.
Thanks for your answer

Why force all platforms to set it if the driver is perfectly capable do
this itself? As I said - this is not a platform-specific feature, it's
chip-specific. What good would it make to have all platforms using

Patch is similar to v3 of the patch.

hi,everyone:
I see that dm6446 contains a 300Mhz ARM and a C64x+ DSP, while

Dm6446's DSP is a little stronger than omap 3530.
DM6446 is much expensive than omap 3530, is it right? But I think
omap3530 is better than dm6446.
