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?).

Hmm I got a Seagate BlackArmor 440 well it was a 420 cuz It came with 2 drives instead of 4. Its one of the first models. Wondering if this is possible with my unit and if "A serial cable was soldered onto the board's CN4 connector which can be used for debugging." IS REQUIRED. I have very little hardware experience but am willing to give it a go. Any thoughts?

@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.
