FS#13213 - Patch 2466 - 'Try mounting as "superfloppy" first' breaks iPods 5G, 4G, nano 1G

Current git build fails to run on 4G, 4G Mini, 5G and Nano 1G ipods.

Rockbox boots but reports an error as ‘installation incomplete’ and no theme is loaded, no database is found and if you go into ‘Files’, no files are found and you cannot write any data to disk (dump identify_info).

Removing this patch and rebuilding allows the above iPods to boot and function normally.

6G Classic and 2G Nano’s do not appear to be affected.

Mini2G-8GB has a CF card fitted
Mini2G-16GBuSD has a uSD card fitted in an uSD-SD adapter in a SD-CF adapter.
All others are stock.

Can you dump the first few KB of the drive (via disk mode) so we can see what's going on?

(I have a theory.. it might be bunnies..)


also, what's the content of settings/debug/partition info


Finally, any dumps need full hw details – exact model, storage particulars (for the non-nano unit anyway)

FWIW I've using git HEAD with a mini2g with no issues.


Thanks for the dumps. It looks like the problem has to do with the partition layout, namely the presence of multiple partitions.

(I think the underlying root cause is the removal of the partition type id check rather than mount order issues)

Just done the following with a 4G Color,
Write 0's to first 2GB.
Connect to PC and restore with iTunes.
iPod boots and plays OK
Use Rockbox Utility V1.4.1 to install Rockbox.
Rockbox starts, reports 'No .rockbox directory' and 'installation incomplete'.
Select 'File', no files found. No music available.
Reboot into Apple OS.
iPod plays OK. Rockbox doesn't.


Try applying this patch:

Tried on a 4G Color and appears to work OK.
Will try on the others


I updated the patch after you reported success, can you reconfirm with the latest iteration?

Patch 48ac569 causes 'No partition found. Insert USB cable and fix it' on a Mini1G.
Patch 6b2190f worked on all targets.


Thank you! I've reverted to the older version.

Patch 5 (7249fabe63) works on Mini1G, Nano1G, Mini2G,4G Grescale, 4G Color, Video 5G.
