NSA-Backup-Device/Log

Here is my log for building and installing Debian on the D-Link DNS-320 NAS. If anything is unclear, you have questions or improvements please drop me an email dns320 to AT to woerm DOT at.

Compiling u-boot.kwb

• Clone u-boot from master-branch git clone -b dns320_support https://github.com/lentinj/u-boot.git
• set export-variable export CROSS_COMPILE=arm-linux-gnueabi-
• make distclean
  
  • tells me make: arm-linux-gnueabi-gcc: Command not found
  • export CROSS_COMPILE=arm-linux-gnu- correct variable on Fed
• make dns320_config
• make u-boot-nand.kwb
• change u-boot/board/d-link/dnskw/kwbimage.dns320.cfg BOOT_FROM nand to BOOF_FROM uart
• make clean && make dns320_config && make u-boot-uart.kwb

Starting u-boot.kwb over rs232-adapter

• connect RX => TX, TX => RX, GND <=> GND
• download kwuartboot-0.1
  
  • make
• sudo ./kwuartboot /dev/ttyUSB1 u-boot-uart.kwb; sleep 5; sudo ./kwuartboot /dev/ttyUSB1 u-boot-uart.kwb; sudo screen /dev/ttyUSB1 115200
  
  • find out which is your tty device by looking into your kernel ring and searching for the string tty dmesg |grep -i tty
  • Connect RS232, connect power, run the command, push power button once, wait, press any key for interrupting u-boot
  • quit screen with pressing ctrl+a once, then push d once

Bootstrapping debian

• debootstrap --verbose --foreign --arch=armel --variant=minbase --include=module-init-tools,locales,udev,aptitude,dialog,ifupdown,procps,iproute,iputils-ping,pump,nano,wget,netbase wheezy rootfs http://ftp.uk.debian.org/debian
  
  • debootstrap requires qemu-arm-static, which is not provided by Fedora - maybe I need to compile it by my own using –static
  • I am using an ubuntu vagrant image for bootstrapping debian vagrant box add ubuntu64 http://cloud-images.ubuntu.com/vagrant/precise/current/precise-server-cloudimg-amd64-vagrant-disk1.box
  • Installing qemu sudo apt-get install qemu-kvm-extras-static qemu-kvm-extras qemu qemu-user qemu-user-static
• cp /usr/bin/qemu-arm-static rootfs/usr/bin/
• chroot rootfs
  
  • ./debootstrap/debootstrap --second-stage
  • apt-get clean
  • dpkg-reconfigure tzdata
  • dpkg-reconfigure locales
  • passwd
  • exit #:)
• rm rootfs/usr/bin/qemu-arm-static
• sudo mkfs.ubifs -v -r rootfs -m 2048 -e 129024 -c 1016 -x zlib -o ubifs.img
  
  • requires on ubuntu sudo apt-get install mtd-utils
  • side note: You can copy files from your vagrant box to your vagrant
    folder with cp /vagrant/

Kernel Compiling(Additionally)

• downloading linux-2.6
  
  • Did not work, trying it with 3x Kernel now
• setting alias for cross-make
• copying kirkwood_defconfig and adding extra options
