Ipod 3G booting rockbox cannot find "Linux.bin"
delbydev:
After installing RockBox (auto or manually), running ipodpatcher.exe - it,
I rebooted the Ipod and it showed the Apple and the displayed the following message:
"undefined instruction at 00046498 (0)"
Using Menu+Play, Lock keypad, boots the ipod bootloader succesfully
Using Menu+Play, and REW+FWD boots the Disk Mode sucessfully
It just seems impossible to boot from the rockbox bootloader (see message) above
First time after reapplying ipodpatcher I get another response
"data abort at 20002002 (0)" - in fact this is various addresses
Background
Internet connectivity:
Windows XP Pro
Firefox
Apple Ipod 3G -- Apple Firmware Version 2.3
Please can anyone advise? Am about to try other but rockbox does meet what I am looking for ...
:(
Steps
1) Downloaded Current Build from http://build.rockbox.org/ on 05 Jan 2007 - installed automatically - no joy - so removed .rockbox and unzipped files directly (manually)
2) Downloaded and ran ipodpatcher.exe

>> Why is this?
Der Papst:
I think the problems you are having is because it seems that rockbox is currently broken on 3G iPods (infact all PP5002, that means 1G and 2G iPods too).
Yesterday someone had similar problems in IRC (though he was using Loader 2 as bootloader).
The only solution that comes to my mind is that you have to get an older build of Rockbox. On my 3G i run a build of November 07 which works fine. However i was not able to find the link to the build archives anymore so i guess you have to compile an older build yourself, using
--- Code: ---svn checkout svn://svn.rockbox.org/rockbox/trunk -r {YYYY-MM-DD} rockbox
--- End code ---
to check out an older version of the source code.
If you hold play during startup the rockbox bootloader tries to load the linux kernel from the iPodLinux Project.
linuxstb:
Some of the download mirrors seem to keep older versions around. It's a lottery (depending on which mirror you connect to), but try looking here:

Perfect! Thanks very much - up and running within 5 mins.
Glad it was not my dumminess, sad that it was a bug
Thanks again
jhMikeS:
You can always keep trying newer builds. You've got about a 50% chance that a daily or cutting edge build will work or if you can edit and compile souce, you may add the right number of "nop;" statements into main.c (takes a little experimenting).
