5). Save the configuration to flash
6.4 NFS Root Development Deployment
During developement one typically downloads the kernel via tftp and uses nfs
for the root filesystem.
1). On the host, copy the kernel and device tree file to the tftpboot directory
2). Set nfsboot parameter
3). Now boot the board
4). To have u-boot automatically run nfsboot at boottime set the bootcmd
6.5 How to boot from net_ramboot
1). Copy the kernel, device tree file and ram file system (rootfs.ext2.gz.uboot-

common) to tftpboot on the host computer.
Ram file system, rootfs.ext2.gz.uboot-common is generated by ltib
packages. Please refer to the LTIB help documentation.
