Flash instruction:
NOTE: this process uses a serial connection. It will upgrade the
bootloader and reset the bootloader environment variables
TFTP server setup
- Setup PC with TFTP server set the PC IP to 10.4.50.5 as TFTP server
- Copy these files to TFTP server location
- u-boot.kwb
- seagate_blackarmor-nas220-initramfs-uImage
- seagate_blackarmor-nas220-squashfs-sysupgrade.bin
- seagate_blackarmor-nas220-squashfs-factory.bin
Seagate NAS setup
- Connect LAN cable between PC and seagate device
- Connect to serial to seagate device
Install u-boot
- Boot seagate device and stop in bootloader by pressing any key
- run 'printenv' from u-boot and save the values
- tftpboot 0x2000000 u-boot.kwb
- nand erase.part uboot
- nand write 0x2000000 0x0 ${filesize}
- reset
Update MAC address in u-boot env
- Stop in u-boot by pressing any key
- Get your MAC address from your saved printenv. Is also on chassis
- setenv ethaddr <your MAC>
- saveenv
Option 1 (recommended) - Install OpenWrt via initramfs and sysupgrade
- tftpboot 0x2000000 seagate_blackarmor-nas220-initramfs-uImage
- bootm 0x2000000
- *OpenWrt should be running now, however it is not written to flash yet*
- From the running instance of OpenWrt use Luci's "flash image" feature
from the web site or use sysupgrade from the console to write
seagate_blackarmor-nas220-squashfs-sysupgrade.bin to flash
Option 2 - Install OpenWrt by flashing factory image from u-boot
- nand erase.part ubi
- tftpboot 0x2000000 seagate_blackarmor-nas220-squashfs-factory.bin
- nand write 0x2000000 ubi ${filesize}
- reset
