What changes were made for the 80GB iPod firmware port?

(1/1)

Hello,

Firstly, I saw the note on the Homepage and in the SVN commit section, and congratulations on finally getting Rockbox ported to the 80GB iPod.  I know this will make lots of iPod users (and existing Rockbox users) very happy.

I know you guys must be quite busy, but perhaps you could post a brief on what changes were needed to adapt the 30GB version for the 80GB?  I'm assuming these included hard disk recognition and file allocation, maybe processor threading, and the increased battery life?  Or is there more?

Sorry, I know this is probably the last thing you want to do after working so hard on this, but I'm really interested from a technical point of view as to the changes between the two versions.

Thanks.

H.

As far as I know the only changes required to get Rockbox running on the 80 GB iPod was to the ATA driver. Everything else is identicaly to the 30 GB verison.

Did you see the comment?

"ATA driver: * Support for drives with large physical sectors and no support for partial access in the firmware (i.e. Toshiba MK8010GAH - iPod G5.5/80GB). Sequential writes with a single 512-byte buffer to that disk are really slow, so this is an intermediate solution that allows to adjust the FAT driver and the file system gradually. * Assume multisectors = 16 if the value reported by the drive is invalid (also MK8010GAH)."

Its pretty specific.  If you're really curious, you can click the diff link and see what functions changed, which gives a pretty good idea what needed to be fixed.

There was also the wiki page (which is now relegated to obsolete status) which detailed what the issue was.

Thanks, no I did not see that comment, so i must have overlooked or misread it.  Thanks.
