Cannot install Rockbox to OSOS (Nano2G)

[Darkknight512]

I am trying to install Rockbox to OSOS with the commands on the wiki to a Nano2G with the Rockbox.ipod file from the current build.

Nothing changes on the ipod, this is for "OSOS contains only Rockbox" on the wiki

Thanks

Those installation methods do not apply to the Nano 2G. The Nano 2G boots differently, and needs a different process.

[Darkknight512]

Any ETA on that or "Just hang out for a while, working on more important things"

I think I might get on coding some plugins or something once I'm done coding for VxWorks (Robotics team)

Just a quick question, which one would you reccomend for da noob, "Windows: Set up a Cygwin development environment OR set up a coLinux development environment OR set up a VMWare development environment OR set up a Interix development environment. "

Different options exist on the Nano 2G because it doesn't work the same way. Instead of appending the bootloader to the existing OSOS image, the bootloader is always placed in OSOS on its own, and the existing OSOS image renamed to something else. Thus, it's already booting using something rather like method 3 on that list.

Installing Rockbox to OSOS instead is *probably* not much quicker, but should be possible, I just don't know offhand exactly what to do, I don't have a 2G.

I've put a note in the wiki page saying that the instructions only apply to the older models.

The difference is that the firmware images on the Nano2G are encrypted.  The filename convention ".ipodx" is used for these encrypted images.

The default installation on the nano2g is the same as option #3 on the ipodpatcher wiki page - the bootloader is stored (encrypted) in the main OSOS partition, and the Apple firmware is moved to an "OSBK" partition (which the Apple bootloader ignores).

If you want to put Rockbox in the OSOS partition, then you will need to create a "rockbox.ipodx" file from the "rockbox.ipod" file, then use "ipodpatcher -wf rockbox.ipodx".

This encryption has to be done on an ipod (using the hardware crypto unit), and there's a viewer plugin (crypt_firmware) included on the Nano2G which does that job - just "open with..." rockbox.ipod with crypt_firmware, and a rockbox.ipodx file will be created.

(if anyone wants to update the ipodpatcher wiki page, please do...)

I will gladly update the wiki, may I please have access?

Done.

I use openwith - cript_firmware on rockbox.ipod. I see encrypting for 2 seconds then, *PANIC* Stkov main

Edit: It also put the ipod in recover mode.

Edit: I just recovered the device and tried again, it worked this time, should I still file a bug report on the first crash?

Edit: Did it again, same crash, no recovery mode this time though

If you're going to update it, please try and explain the differences, and which methods apply. Measurements of any difference in boot speed would be good as well, though this is very hard to do well without modifying the bootloader to time the process.
