hello everybody! i finally managed to build a toolchain for arm (arm-uclinux), compile the kernel with patches for build from ppc (as described by steven in his email), patch the firmware etc. my question is: what about partitioning? mac ipods have a different partitioning. do i have to repartition my ipod to match the win-ipod version? and if i do: are there any restrictions about partition sizes, layouts etc? or is it sufficient if i make a firmware partition of ~35 megs and split the rest of the disk into different partitions? i'm asking because... well, since i'm going to destroy my mp3 collection anyway (or maybe not -- i could do a dd from my 3rd partition [data partition on an mac-ipod] and mount it read-only via loopback to get back my data -- there is a HFS+ filesystem patch somewhere around the net which seems to work well in ro-mode :-) i'd like to change partitionig scheme. i want my ipod to have different partitions, i.e. for / /var and /home/music. / and /home/music could be mounted read-only (i assume ipod-linux will be just as upset about power-off while system is running as any other linux) and only mount a small partition (about 200 MB?) rw, for files that need to be accessed rw access while system is running (like several log files, and maybe some address books...) best regards, florin (with a strong desire to irrecoverably destroy his ipod). |

Hi again, I'm not 100% sure about the partition on the iPod, I haven't experiemented that much (infact I'm just using the standard layout on my win iPod). I imagine the bootloader is quite sensitive to changes in the partitioning. I believe however that if "data" partition for a mac iPod is converted from HFS+ to FAT32 it will still work with iTunes and the Apple firmware. Can anyone confirm that? Anyhow except for experimentation I would suggest leaving the partitions as they are currently. Until an alternate usable firmware is available being able to revert to the Apple firmware is very useful (required for me!). In the long run using an ext3 filesystem might be interesting to get better usage of the available disk space. Regarding the power-off situation the only real danger is is the reset function of the iPod. The lower battery power situation should be easy enough to handle (eventually :) by the kernel. cheers, bern.
