I have config the CONFIG_VIDEO_DAVINCI_VPIF_CAPTURE and CONFIG_VIDEO_DAVINCI_VPIF_DISPLAY. And when I run the app , it will show follow message then exit. vpif_display: dma_alloc_coherent size 4149248 failed. I show my memory with free command, the result are: root@arago :~# free total used free shared buffers Mem: 92696 17528 75168 0 0 Swap: 0 0 0 Total: 92696 17528 75168 and the result of cat /proc/buddyinfo as follows: root@arago :~# cat /proc/buddyinfo Node 0, zone DMA 3 10 10 20 5 4 0 1 1 3 25 it's seem that the memory is enough. BTW, the DVSDK is ti-dvsdk_omapl138-evm_4_02_00_06.
