Server Configuration and Image

Configure a tftp server on your platform of choice using 192.168.11.149 as its IP address. You should also have serial port access to the device so that you can issue commands to U-Boot. The root directory for your tftp server must contain the files you need to boot your LinkStation with, in this case uImage_2.6.25.1.

Using a Serial Port Connection

Using the serial port app of your choice (e.g. minicom), establish a connection to your LinkStation and power it up. You will see the usual:

hit any key to switch tftp boot.      
                                         

When you see the last line above stop the boot process by pressing any key twice or so.

You should see the UBoot prompt then:

Marvell>> 

You then must pass the correct boot parameters to UBoot, tftp the image into your LinkStation, and boot it, by entering each of these commands at the UBoot prompt:

setenv bootargs console=ttyS0,115200 root=/dev/ram0 rw
tftp 00800000 uImage_2.6.25.1
bootm 00800000

If successful you will see something like this:

Marvell>> setenv bootargs console=ttyS0,115200 root=/dev/ram0 rw
Marvell>> tftp 00800000 uImage_2.6.25.1

kuropro login: 

You are now booted w/ a foonas-em image. You should be able to log in with username "root" and password "hydr0g3n" over your existing serial port connection or telnet it via its DHCP assigned address. Should DHCP fail it will default to the IP address of 192.168.11.150.

Using a dummy initrd (without serial port connection)

You can also boot foonas-em via tftp if you provide a dummy initrd. You may even use the stock one as it will be totally ignored because foonas-em will boot the initramfs instead of the initrd.
