Seagate BlackArmor 4XX (e.g. 400, 420, 440) NAS

00-status.md

Device Status

• A serial cable was soldered onto the board's CN4 connector which can be used for debugging.
• A USB drive is attached containing a debootstrapped Debian Jessie armel on an ext4 filesystem.
• The original flash was completely erased.
• A new version of u-boot provided by Evgeni was installed onto the flash.
  • Work in Progress Patch: https://github.com/bantu/u-boot/compare/master...sg-ba-440
• The new u-boot version is capable of loading files from ext4 filesystems, the old one was not.
• u-boot loads three files: /boot/uInitrd, /boot/uDtb, /boot/uImage
• The kernel is provided by the linux-image-kirkwood debian package.
• The uDtb is a Device Tree Binary describing how the different parts of the hardware interact.
• A new device tree has been constructed
  • Work in Progress Patch: https://github.com/bantu/linux/compare/master...kw-ba-400-dts
  • Useful information about parts of the hardware can be found in the commit message

Working hardware (under Debian Jessie)

• 2x Gigabit Ethernet
• 4x SATA
• USB
• FAN (via DT and installing fancontrol package)
• LCD (See new-lcd.sh)

Open Problems

1. The device does not properly shut down yet.
2. Wake on LAN (if supported at all).
3. Checking that buttons and LEDs work correctly.

Stock Software

• U-Boot 1.1.4 (Sep 9 2010 - 14:52:19) Marvell version: 3.4.18
  • Misses patch http://lists.denx.de/pipermail/u-boot/2012-February/117020.html
  • Results in issue https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=658904
  • Alternative to updating u-boot: https://lkml.org/lkml/2012/12/7/321
  • More Debian discussion also in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=658759
  • Another alternative would be to use an uncompressed kernel (via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=658759).
• Linux (none) 2.6.31.8 #1 Fri Nov 4 18:48:15 CST 2011 v0.3.2 armv5tel GNU/Linux
• Source Files by Seagate: http://www.seagate.com/files/staticfiles/support/products/blackarmor/downloads/BA_NAS_4xx_GPL.zip

Random Notes

• Seagate Download Finder maps the Serial Number to Model Number: STAR400
• Would like to run Debian Jessie using Debian Kernel (linux-image-kirkwood)
• Debian's fw_printenv does not work, the fw_printenv provided by the rootfs works (Marvell specific?).

@modernmediagrp The serial cable is not required, e.g. you could flash the updated u-boot from the stock system.

I further modified @bantu's patches: https://github.com/hn/seagate-blackarmor-nas#NAS-440-patch-details . LCD works, LEDs work, some GPIO mappings have been improved/corrected, but unfortunately HDDs 1 and 2 do not work. Any help is welcome.
