Sir, I am also facing the same issue of HDMI port. The *sample_video.avi* does not produce any output on LCD monitor. I have used *Beagle_Revc4_Validation.img* and followed the same procedure as mentioned by Mr. Kishore Kumar Boddu for *bootargs* and *bootcmd* but even though I am not getting output on Monitor and also not able to bring the board in network through USB to ethernet converter. I am using Beagle Board Rev C3 board.
