U-Boot Startup Scripts; U-Boot Update Scripts - Z3 Technology Z3-DM8168-DVR-RPS User Instructions

(8) When you get the u-boot prompt again, enter the commands below. This will enable mounting the
rootfs using NFS and booting the kernel by TFTP.
Z3-DM8168-MOD# setenv bootcmd run boot-nfs
Z3-DM8168-MOD# saveenv
(9) Make sure that the DM8168 is connected to your network and power cycle.
If all went well, the DM8168 system will boot the kernel obtained via TFTP from the Linux PC,
mount a root file system using NFS, and present a "#" prompt. If not, then troubleshoot the
connections, IP addresses and server settings. Look in the .../images directory and make sure
that the code is there. The root file system for the target will be at .../filesys/fs.

8.1 U-boot Startup Scripts

The following u-boot startup scripts are available. Each set up the u-boot variables for a specific
behavior. To make the settings permanent, run 'saveenv'.
setenv bootcmd run boot-nfs
setenv bootcmd run nand_boot_nfs
setenv bootcmd run nand_boot_jffs2
setenv bootcmd run nand_boot_ramdisk
setenv bootcmd run nand_boot_ubifs
