I'm using the DM6446 but the driver is mostly the same. I can allocate
5MBytes with no problems. Are you using the EVM with the default
memory map?

Hi,ALL
I want to output HD signal(I means 720P) using dm355 vpbe Ycc16
interface.The default VPBE resolution is 720x480 or 720x576,so I
need to change this resolution to be 1280x720,and this will result a
problem:I can't allocate enough DMA memory in the dm355 vpbe
driver.That is I can't allocate DMA memory greater than 4M,but If I
want use 720P in the vpbe,I need about 6M for one window.Is the
allocation function dma_alloc_coherent limit(In the drivers/video/
dm355fb.c vpbe_mem_alloc_max function) the memory to be samller than
4M?So what should I do next?
My sdk version is 1_30_00_40.
Any help will be appreciated!
