6.3.1

Booting from a Network

In this mode, U-Boot downloads and boots the Linux kernel from an external TFTP server and
mounts a root file system located on a network server.

1.

Make sure that the

kernel, dtb,

and

ramdisk

are accessible to the board from the

TFTP server.

2.

Configure U-Boot environment variables:

setenv ipaddr

setenv serverip

setenv gatewayip

setenv netmask

setenv bootargs 'root=/dev/ram rw console=ttyS0,9600n8

ramdisk_size=700000 cache-sram-size=0x10000'

saveenv

These serial access parameters are the default values. These values can be changed within the
U-Boot. For details, refer to the U-Boot documentation.

Enter the command setenv bootdelay -1; saveenv to disable the U-Boot auto-boot
feature and let the U-Boot directly enter the command line interface after the next
reboot/power up.
