Hi

I am working on a TDM3730 board, similar to DM37X EVM,

when I run:


root@dm37x-evm:/usr/share/ti/ti-dmai-apps# ./video_loopback_dm3730.x470MV -O lcd
Failed to detect input video standard, input connected?

I am new to linux media architecre,

I find , there is no "/dev/videox" node,alse it seems "/dev/media0" should exist according  to some linux media document.

I have configured the kernel to include "video for linux", "Video capture adapters / TVP5146video decoder"

what other config I missing?

must the "/dev/videox" node be created manually? or It be created after load some kernel modules?

Thanks!
