Scatter-gather DMA support for copying camera frame buffers

[titusstalin]

Dear All,

How can I enable the Scatter-Gather DMA support in MIPI camera frames ?

Any scatter-gather example is available ?

I referred this link and not able to build. Getting errors like Rajasekaran.

Any support is greatly appreciated.

Thanks for your help.

Hi Titus

I am afraid this is not supported in nxp linux bsp, in general for copying

memory buffers one can use mxc_sdma_memcopy_test.c, described in

community like:

Thanks Igor for your reply.

Able to build the SDMA driver (mxc_sdma_memcopy_test.c) separately and able to run the "mxc_sdma_test.c" application.
