DM8148 video capture doesn't work

I'll appreciate if anyboday can look at this issue for me.

DM8148 EVM with the lasted SDK ezsdk_5_05_02_00_dm814x, the video capture by gst-launch dosn't work. I tried many gst-launch v4l2src xx with video format fourcc YUY2, always get output like: GstV4l2Src:v4l2src0: Could not negotiate forma. If change the format fourcc to something else like GRAY, error will be: WARNING: erroneous pipeline: could not link v4l2src0 to omxbasectrl.

Firmware call in load-hd-firmware.sh under /etc/init.d, the line to load v4l2 firmware like:

firmware_loader $HDVPSS_ID /usr/share/ti/ti-media-controller-utils/dm814x_hdvpss_v4l2.xem3 start -i2c 0

And at the bootup phase, get some error like:
