[GoFlex Net] Disabling ipv6

[Wesman26]

So I'm a little hazy on this. What will the serial to ttl adapter allow me to do?

[moonman]

It will give you the ability to:

Edit U-Boot environment
See what happened and watch your device boot up so you can the the errors that it spits out
basically serial will be your terminal to the device without using ethernet
If you completely brick the device (i.e. u-boot is not recoverable) you can unbrick it. (which i don't think is the case here)

But you will need to open up the device. It isn't that difficult. There are only 3 wires that need to be connected.

[Wesman26]

Is there some sort of more in depth tutorial I can find on how to set it up.

[moonman]

I found this: http://www.varkey.in/2011/06/seagate-go ... onnection/

Okay so I finally got my USB to Serial converter in the mail and I have it set up now. This is the output:

And that's where it stops. What should I be doing?

[WarheadsSE]

We need to find out what it is passing to the kernel via cmdline. Please get us either, full boot log, or printenv output

Thanks for all the help!!

[WarheadsSE]

This should turn on netconsole for you.

$this->bbcode_second_pass_code('', '
/usr/bin/fw_setenv ipaddr '10.0.10.6'
/usr/bin/fw_setenv ncip '10.10.10.5'

/usr/bin/fw_setenv serverip '10.10.10.3'

')

Okay, now that I have netconsole up, how can I fix it so that my goflex will actually mount my drive and boot normally?

[WarheadsSE]

You should be able to see what it is trying to mount it as.

Does your rootfs file system match the sata_rootfstype = ext3?
