+====== Seagate GoFlex Home Hacks // Debian ======
 Lots of people working on this. But the information is scattered, and I've not seen the point to some of it... Guess if you want something done right, you have to do it yourself? ;)
 I started this 4/23 so this is a work-in-progress, aka a severely disorganized page. Wiki clean-up usually happens after I put the device back together, and that could take awhile since my free time is limited.
+[edit: 8/1] I guess it'll be some time. This project was short lived. I got debian on it and then it's done. ha. been running fine just another computer on the network now...
+===== bootrom disassembly =====
+someone with dockstar-like device (bootrom 1.11) asked for my dump to compare and see why they cannot boot from serial as we can. my results:
+ASCII dump from U-boot: http://goflex.scottn.us/bootrom121.txt \\
+Binary file: http://goflex.scottn.us/bootrom121.bin \\
+Simple objdump disassemble: http://goflex.scottn.us/bootrom121.dis

 it says it includes the debian patches, but it comes up as normal 2.6.32... meh.
-I added a bit also to arch/arm/kernel/head-common.S so that we need not pass arcNumber. This would help later for making installable without editing bootloader. :P
+I added a bit also to arch/arm/kernel/head-common.S so that we need not pass arcNumber. This would help later for making installable without editing bootloader. :P It seemed that although the Goflex Home has USB/IDE enabled in U-Boot, the arcNumber variable is not. This was partially verified later by a grep of the u-boot sources supplied in GPL release by Seagate.
 We can start serial commands at u-boot to load USB key with [[http://goflex.scottn.us/uMulti-2.6.32-5-kirkwood-goflex|my kernel+initrd]]. For example:

-Creation of the USB key or even ext2 partition on the SATA can be easy with debootstrap. I will attempt emdebian's soon to see if it's dependencies are a bit less a tangled web of bloat. ;)

Debian's running well, just follow [[http://linux.koolsolutions.com/2009/01/07/howto-tell-apt-get-not-to-install-recommends-packages-in-debian-linux/|this guide]] to ensure dumb things like X11 libraries getting installed with openssh doesn't happen.]

-Somewhat unrelated, but I attached a Coby DP-152 I got for $5. Edited the example a bit. 500ms refreshes seem to take about 11% CPU so 5s refreshes take 1% which is more acceptable. Large thread about these little 128x128 LCDs found here: http://forum.doozan.com/read.php?2,2435
+Somewhat unrelated, but I attached a Coby DP-152 I got for $5. Edited the example a bit. Here's [[http://goflex.scottn.us/picframe/lcd4linux.conf|mine]].
