Default Boot Configuration

3.1Default Boot Configuration

Out of the box, the EVM boots from flash and starts the demos automatically after a few seconds when you power up the board. It does not require an NFS mount or a TFTP server to run the standard demos.

Note: The default U-Boot bootargs definition sets "ip=off", which disables the Ethernet connection.

The out-of-the-box boot parameters are listed in Section A.4.1. The following are alternate ways you may want to boot the board:

❏TFTP boot with NAND flash file system (Section A.4.2)

❏Flash boot with NFS file system (Section A.4.3)

❏TFTP boot with NFS file system (Section A.4.4)

❏PAL video mode vs. NTSC video mode (Section 2.1)

To abort the standard boot, press any key in the console window (see Section 2.2). Also see Section A.4, Alternate Boot Methods if you want to change the boot configuration.

Note: It is best to power down the board cleanly in order to reboot, rather than using the reset button or power switch. We recommend that you use the shutdown command to shut down the operating system and unmount the file system before removing power from the board. This will help prevent corruption of the flash-based root file system.

3.2Starting the Standalone Demos

When you connect the EVM hardware, the pre-loaded examples run automatically on your video display. These examples encode and decode audio, video, and speech. There are two ways to use the demos:

❏Standalone. This is the default power-on mode. The demos run automatically with no connection to a workstation in the default boot configuration. This is the mode documented in the rest of this chapter.

The standalone demo was set up by the DVSDK, which copies the file /examples/dvevmdemo to the directory /etc/rc.d/init.d (the central repository for startup scripts). This file is symbolically linked to /etc/rc.d/rc3id/S88demo. When the board boots up and enters runlevel 3, this file is executed to start the demo web server and the demo interface.
