Is there any kuropro UBoot documentation? I can not find anything substantial.

The most extensive information I can find on how UBoot is implemented, with regards to booting from the Hardrive, is here. -> ("The following procedure creates the following partition scheme, and untars a root file system onto p2 (/dev/sda2). Somehow it rewrites the uboot variables allowing a boot from the hard drive.")

Now maybe the Kuro folks have magic pixies in the box doing it but hopefully it's a process mere mortals can also make use of.

There is some on the CD that came with the KuroPro as PDFs. Also I cut out alot of that information and posted it in several places here:

the specific parts you are looking for are here though:

What I am looking for is how exactly do the two files ChangeMeDevHDD and ChangeMyUbootEnv affect U-Boot and is it a one way street. So once I put them in the flash share and it starts the Kuropro booting off the hdd can I reverse it or adjust things. Basically that page tells me the 3 ways in which uboot boots but doesn't say how we can take advantage.

admittedly the document is a bit technical, you can fix it up if you like. The uboot settings/commands here the first set of lines are "setenv" commands to set uboot settings:

would get your kuropro back to the way it shipped to you.


The settings here:

http://www.linkstationwiki.net/index.ph ... settings_2

are how your kuropro is now

I'm not exactly sure how those two files (ChangeMeDevHDD and ChangeMyUbootEnv) do the uboot-setting changing. I'm sure it's a simple matter of scripting, however I haven't seen anyone post this for sure. If someone could figure that out cleanly (to go back and forth) possibly kuropro hacking could be done without serial access.


Edit: There is a uboot wiki here: http://www.denx.de/wiki/DULG/Manual
