• 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

• A TFTP server is needed to serve files to uBoot

sudo dnf install 'tftp-server'

sudo firewall-cmd --add-service='tftp'

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'

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'

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'

• Needed to communicate with uBoot shell over network

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

• 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'

• 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

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

• 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'

• 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
