Information

  • Seagate Personal Cloud 1)
  • Debian 2) 3)
  • vsftpd 4)
  • For whatever reason, the bootloader settings don't stick when the NAS looses power for a bit; these instructions work, but not reliable

TFTP Server

  • A TFTP server is needed to serve files to uBoot
sudo dnf install 'tftp-server'
sudo firewall-cmd --add-service='tftp'

Debian Installer Files

uImage

sudo wget -O '/var/lib/tftpboot/uImage' 'http://ftp.debian.org/debian/dists/stretch/main/installer-armhf/current/images/network-console/seagate/personal-cloud/uImage'

uInitrd

sudo wget -O '/var/lib/tftpboot/uInitrd' 'http://ftp.debian.org/debian/dists/stretch/main/installer-armhf/current/images/network-console/seagate/personal-cloud/uInitrd'

Device Tree Blob

sudo wget -O '/var/lib/tftpboot/armada-370-seagate-personal-cloud.dtb' 'http://ftp.debian.org/debian/dists/stretch/main/installer-armhf/current/images/device-tree/armada-370-seagate-personal-cloud.dtb'

clunc

Information

  • Needed to communicate with uBoot shell over network

Acquire and Compile

git clone -b 'master' 'http://git.lacie-nas.org/clunc.git' ~/'clunc' && cd ~/'clunc' && make && sync

Execute

  • This needs to be running before the NAS is given power
  • Getting the IP for the NAS in this state is tricky; had to set a static ARP from AdvancedTomato GUI
cd ~/'clunc' && ~/'clunc' -vi '192.168.1.129'

Debian Installer Initialize

  • Following commands pulls the Debian installer files from the TFTP server and executes them to initiate the installer
setenv serverip 192.168.1.151
setenv ipaddr 192.168.1.129
tftpboot 0x2000000 uImage
tftpboot 0x5100000 uInitrd
tftpboot 0x5000000 armada-370-seagate-personal-cloud.dtb
setenv fdt_high 0xffffffff
setenv initrd_high 0xffffffff
bootm 0x2000000 0x5100000 0x5000000

Debian Installer

  • No real tricks to install; just follow on-screen instructions

Debian Installer Finalize

clunc Execute

  • This needs to be running before the Debian installer reboots at the last step
  • IP should theoretically be the same as before
cd ~/'clunc' && ~/'clunc' -vi '192.168.1.129'

uBoot

  • Following commands tell uBoot how to boot Debian on its own
setenv debian_kernel_addr 0x2000000
setenv debian_initrd_addr 0x5100000
setenv debian_dtb_addr 0x5000000
setenv initrd_high 0xffffffff
setenv fdt_high 0xffffffff
setenv debian_boot_part 1
setenv debian_kernel_img /uImage
setenv debian_initrd_img /uInitrd
setenv debian_dtb_img /dtb
setenv debian_bootargs setenv bootargs ${console}
setenv debian_load_image 'ext2load ${disk_iface} ${disk_num}:${boot_part} ${kern_addr} ${debian_kernel_img} && iminfo ${debian_kernel_addr}; ext2load ${disk_iface} ${disk_num}:${boot_part} ${debian_initrd_addr} ${debian_initrd_img}; ext2load ${disk_iface} ${disk_num}:${boot_part} ${debian_dtb_addr} ${debian_dtb_img}'
setenv debian_boot 'hdd start; ide reset; setenv boot_part ${debian_boot_part}; for disk in ${disk_list}; do run disk_expand; echo Booting Debian from disk ${disk}...; run debian_load_image; run debian_bootargs; bootm ${debian_kernel_addr} ${debian_initrd_addr} ${debian_dtb_addr}; done'
setenv bootcmd run debian_boot
saveenv
run bootcmd
