if it is successful will it display anything else?
Normally yes. You should see the kernel bootlog. Here
you can see a bootlog of the 2Big2. But as I said before, there is no law which compels the kernel to log to the serial port. The messages you see are from the bootloader, and from the zImage 'piggyback', which decompresses the kernel. But the kernel itself seems silent. (Or doesn't boot at all).
On the other hand, the smaller cousin of the 2Big (the EdminiV2) boots verbosely. I wouldn't know why Lacie changed that.
BTW, where did you connect your serial port? I'm only aware of one set of pins, but the Orion SoC has two ports. If you managed to use 'the other one', I can imaging uboot uses both, while the kernel uses just one.
You could try the edminiV2 kernel
(sda6). It won't be able to boot the 2Big, I think, at least not as 2Big, but I'm sure that kernel is verbose, and should show something, before ending in a kernel panic.
A third option is that the commandline has to specify which serial port to use for logging, and doesn't do so for some reason. Have a look in the uboot settings. Try 'printenv'. Somewhere the commandline is specified, it contains something like 'root=/dev/sda7', and you could try to add 'console=ttyS0,115200n8', if it isn't there already. After that boot with 'bootd'. You cannot just reset the box, as the environment isn't (and will not be) saved in flash:
*** Warning - bad CRC, using default environment
ok, i intrupted the boot and type "dhcp" and it got an ip, and trying to load a image "3D0100A.ing" why is that?
Don't know. How do you know it's trying to load that image?
is there other way i can restore the image using this console?... tftp? i am very new to this...
Probably not. 'Restoring the image' involves writing to disk, and I don't think u-boot has that possibility. In your case connecting the disk to another system is easier anyway. But you are right, u-boot *can* have advanced ways to upload a kernel (or anything) using tftp or serial. Something like this
. (BTW, in that example the kernel is flashed to nand. Do NOT try to do that, in the Lacie the nand only contains the bootloader. Overwriting that will kill the box forever)
