DM6467 framebuffer

Sivaramkrishna Neeruganti

hi,

i am porting android into dm6467EVM board.i am not able to find /dev/fb special file when booting davinci staging kernel on the DM6467EVM board.However i can find /dev/video0,../dev/video3 for v4l2 devices.

please confirm me whether DM6467 supports framebuffer.if it doesn't support framebuffer ,do we have to port framebuffer or do we have to look for some other alternatives.

as u know Android relies on framebuffer for the display,so we should somehow put up this framebuffer functionality for porting Android on DM6467EVM.

please reply as soon as possible.

Thanking You,
Siva.

Hi,

DM6467 does not support frame buffer driver since there is no graphics pipe line in the hardware itself. It has only video pipelines. Still it can be supported, but only for the YUV422 format.

Thanks,

Hi,

Thanks for the reply.

Android depends on the framebuffer device for the graphics.keeping this in mind can u please elaborate how Framebuffer driver can be implemented with existing hardware support (i,e Video pipelines).
