Specific Configuration

Interfaces

The default network configuration is:

Interface Name Description Default configuration
eth0 Ethernet port DHCP

Failsafe

The GoFlexNet cannot be put into failsafe mode by pressing the button.

It can however be put in failsafe mode using serial console and pressing 'f' and <enter> when prompted during boot-up

Buttons

The GoFlexNet's only button is not configurable and inevitably performs a hard reset when pressed, the button open the bridge between the positive pole and the power cord.

Crypto Hardware Acceleration

Photos

for serial cable (nokia's DKU-5, CA-42 and etc ttl…), 115200 8n1:

NOTE: The pins to use are the ones "covered up" by the tips of the arrows, i.e. the pins in the row toward the outer edge of the PCB. (for comparison, see here)

for enable 3.5" disks (3 pins sata power to +12V DC):

NOTE: The ellipse in the picture indicates three pins for Serial ATA +12 V. (Multiple pins are used for current (Ampere) considerations, compare https://en.wikipedia.org/wiki/Serial_ATA#Power_connectors.)

example:

Opening the case

There are no screws - the bottom cover is held by ten plastic snap on clips, three on the sides and two on the edges. To open the case, gently pry all around with a thin screwdriver until it is open.

The serial pins are accessible without further disassembly.

SSH

Connect device to Ethernet port. To prevent automatic updates by cloud engines (which may disable ssh access), use a separate switch or disconnect your router from the internet. If the ssh access was disabled by the automatic cloud engine update service, you need to login there and re-activate ssh.

Find IP address, BE and EF are the last two bytes of the MAC of your device (printed on the bottom of the GoFlexNet)

root@host ~ # ifconfig eth0 169.254.1.0 
root@host ~ # nmap -e eth0 -sP $(printf "169.254.%d.%d" 0xbe 0xef)
Connect to IP address via ssh (root / stxadmin) to see if it works.

Backup original firmware

Login to the original firmware via SSH (enable it first in popoplug site) or Serial cable (nokia's CA-52, DKU-5 and etc ttl…). Plug the flash drive (FAT32) to USB port in Seagate GoFlex Net, then:

mkdir /tmp/backup
mount /dev/sda1 /tmp/backup
cd /tmp/backup
wget http://download.doozan.com/uboot/nanddump
chmod +x nanddump
./nanddump -nof uboot-mtd0-dump /dev/mtd0
./nanddump -nof uboot-original -s 0 -l 0x80000 /dev/mtd0
./nanddump -nof uImage-mtd1-dump /dev/mtd1
./nanddump -nof rootfs-mtd2-dump /dev/mtd2
umount /dev/sda1
To create an image of mtd0, you need to dump the nand without ecc. using "dd if=/dev/mtd0 of=mtd0.DOESNOTWORK" will automatically do ecc for you and will result in a corrupt image.

Restore original firmware via serial cable and tftp-server

Recovery of a bricked uboot *without* jtag

Unlike the dockstar, the goflexnet has a newer bootrom which supports serial boot. [http://forum.doozan.com/read.php?3,7852,7852]

wget ftp://ftp.denx.de/pub/u-boot/u-boot-2013.10.tar.bz2
tar jxf u-boot-2013.10.tar.bz2
cd u-boot-2013.10/tools/
gcc -o kwboot kwboot.c
./kwboot -b /tmp/openwrt-kirkwood-goflexhome-u-boot.kwb -t -p -B 115200 /dev/ttyUSB0

Now the uboot is loaded into ram and executed. You have to flash u-boot into nand. See below how to flash it.

------
load_image uboot.mtd0.goflexnet.original.kwb 0x800000

or you can erease nand and native write to nand:
------

nand erase 0 0x0 0xa0000
nand write 0 uboot.mtd0.goflexnet.original.kwb 0 oob_softecc_kw
