Installation / Removal > Rockbox Utility

Upgrading to latest fw on iPod 5.5 broke rockbox loading

(1/2) > >>

So for the past few hours I have been trying to figure out why, but after upgrading to 4.0, rockbox no longer loads with the error "Can't load rockbox.ipod" - but it does exist. I do not see a splash screen, it jumps straight to this error.

And thankfully, I had taken a backup of the .rockbox folder beforehand, and rename my .old-rockbox to .rockbox it works fine.

I'm really at a loss - I have no idea why it just doesn't work. I've removed and reinstalled the bootloader several times, cleaned up the .rockbox folder that doesn't work and even manually installed it and it's all the same.

Thanks in advance!

The number of sectors in the partition being a negative number sounds bad :)

Is there some older version that would talk to your flash adapter?

Oh wow I didn't even notice the negative number lol

Yep - dev build b3e6b12266-240619 is what I am currently able to run, which was one of the dev builds from last year (judging by timestamp in the version June 19th last year) and it works perfectly.

Ignore the negative number, that's due to printing a large unsigned number as unsigned.

What I'd like to see is a partition table dump, ideally though use of fdisk.   As an alternative, grab the latest daily build and try again; it will show more information on the error screen.

(Modern rockbox is stricter in some ways, and laxer in other ways, in its ability to mount a filesystem.  It's really important to identify what is going wrong here)

I can reformat if needed - but I'd prefer not to obviously, just takes a long time to re-load and I use this daily. Also - I was going to give you a picture of the latest dev build (4/25 build) screen too, but it looked the same as the other screen.
