This is to summarize the current development status Thanks in advance Gaetano You can find a discussion of the 80GB iPod in our user forums in this thread: http://forums.rockbox.org/index.php?topic=7738.0 In that thread, GodEater described the current status as follows: We (mostly myself, Amiconn, and Jeffb) have arrived at the conclusion that the disc in the 80GB is ATA-7 compliant - based on the information from the identify_info returned by the ATA controller when it's queried. It's returning some curious information that we're pondering currently : According to the information we're getting back - there are more logical sectors on the disc than physical. We're not sure if this is relevant or not. The information on multi-sector read/write support doesn't comply with any version of the ATA standard that we're aware of. Regardless of this - even trying single sector reads fails.

ATA help needed for iPod Video 5.5G port (UNFINISHED patch included)
For the past couple of days, I've been trying to get the Rockbox
bootloader working on my 5.5G iPod Video. I've managed to get it to the
point where it reads the checksum and model name from rockbox.ipod, but
then it hangs somewhere in ata_read_sectors() while reading the rest of
the image. I haven't modified ata.c at all, and I don't see why it
should crash in there -- not that I really understand the function.
The problem this patch addresses is that while the hard drive has normal
512-byte sectors, the filesystem has a logical sector size of 2048
bytes. It's presented over USB as a 2048-byte-per-sector HDD, so I can't
just reformat the partition with a sane setting. Heavens, how I would
_like_ to.
All the patch does is quadruple the numbers read in the partition table,
quadruple the number and addresses of sectors read and written by the
FAT code, and make bpb_is_sane() expect 2048-byte sectors. I haven't
quite finished doing that -- the fsinfo accesses are untouched, at the
least. But, again, I don't see what I've done that would lead to a crash
in ata_read_sectors(). I can't help but feel that I've done something
foolish.

iPod Video 5.5G boot partition
Well, hopefully this will help someone figure out how to get the bootloader onto the 5.5G. It's the boot partition from my 5.5G 30GB iPod Video. http://kalthare.dyndns.org/ipod-video-5.5g-boot.zip It's a fifteen megabyte zipfile, and the decompressed partition is about a hundred megs. -- Rob signature.asc Description: OpenPGP digital signature
Patch to increase lcd speed on the ipod video.
Patch to increase lcd speed on the ipod video. Decreases runtime of lcd_update_rect by an average of 0.1 ticks per call, or 1 millisecond; and up to three milliseconds max. This increases the maximum frame rate by about one to one-and-one-half frames per second. Using the test_fps plugin, the results for the unmodified code, on my ipod, are: 1/1 21.5 fps, 1/4 44.5 fps, with CPU at 30MHz 1/1 37.0 fps, 1/4 57.0 fps, with CPU at 75MHz With this patch, my results are: 1/1 22.5 fps, 1/4 46.0 fps, with CPU at 30MHz 1/1 38.5 fps, 1/4 58.0 fps, with CPU at 75MHz The patch uses Duff's Device to unroll a loop.

(how do the Sony minidisc ones work?) ideally one that is still in production. gOn sony minidiscs the buttons use a resistor network with differentvalues for each button. The ones with a display use serial comms forthis part of it AFAIK. It's a while since I had one though.

Thanks :) i think i will hold off until someone makes a small 60gig player with less lock in, and it inspires the devers here to port to it :) undocumented propriority chip proprietary? I shall also wait for one that has a dictionary built in ;-P (like the iStation-i2) g

i think i will hold off until someone makes a small 60gig player with less lock in, and it inspires the devers here to port to it :) That reminds me: Anyone heard anything new from Neuros? Their concept of a fully open (hardware and software) platform seemed quite promising. At least I noticed there was a meeting with the rockbox developers. cu, John
