5.2. Booting via tftp
To use tftp booting, either the management port or the Base Interface port are available
to connect to the tftp server. Table 5-2 describes the details.

5.3. Booting via NFS
To boot to linux in U-Boot using Network File System (NFS), some NFS Server
configuration needs to be in place as shown below.
/etc/exportfs file should contain the directory information for the file system.
#
cat /etc/exportfs
/tftpboot/aTCA-N700T/RFS/rootfs *(rw,no_root_squash)
#
exportfs -> exportfs reconfiguration
# mknod rootfs/dev/console c 5 1 -> Generate a special file in rootfs/dev/
On U-Boot, configuration setup is needed for NFS boot-up. Pre-defined U-Boot
environment variables can be used.
