[Robert D <ro...@op...>]

Hey,

You emailed me a while ago asking me the same thing - kinda, unfortunetly i
lost a bunch of emails a while ago when my system went down - sorry about
that.

Anyways - i am a windows programmer and i was going to play around with
C/C++ and making an interface for the iPod, but it looks like you beat me to
it.

I would be very interested in helping with the project though, maybe we are
in need of a sourceforge site? Heh.

Robert.

[Ipodlinux-devel] Re: keypad problem

[damien m. <Dam...@li...>]

Hi,

thank for the the advice about keypad (opening "/dev/console") now it 
work really well, i'm so proud of using the wheel in my code :) .


I'm currently doing a little interface (gui) for my g3 ipod, currently i 
can only navigate in the directories, changing contrast with a slider, 
and  starting executables. To do this i have a little graphics library 
(drawLines, putPixel, putSprite, changeContrast).
Do some of you  have similar project ? Maybe we could merge, or define a 
common interface where we could plug our functions ?

Is their any people interested ?

Cheers,
Damien

[Robert D <ro...@op...>]

 Did you compile in firewire? If so that is the reason. Try to recompile
again without firewire and it should work.

[Ipodlinux-devel] Graphics library...

[damien m. <Dam...@li...>]

Hi,

as i said in a previous post, i have done a tiny (and buggy) graphics 
library for the ipod with a pseudo emulator (in opengl) to make the 
developpement easier. (i have just readed about nanogui from the mailing 
  list archive)

Currently i have:
- drawHorizLines
- putPixel
- get/setContrast
- putSprite
- drawFont with font size of 6x11 et 8x8

as soon as debugged (the putsprite at any position give me a headache) i 
'll release this. I also have a tool to convert from header files 
(exported by gimp) to ipod_sprite format.

If you have, 4 colors artwork, fonts, images, icons
i'm very interrested in collecting them.


The questions now...

Do somebody has informations about the ipod display ?
- speed in the differents mode ?
- is it better to directly render on the screen or having a double 
buffer in memory (like in fb) ?
- how to render viewable basic animation ?

For what i know, incremental update is much more viewable than deleting 
everything followed by a redraw (i'm so sad that ipod haven't an GBA 
display :) )


The existential part know:

Currently i disconnect the fb driver of the kernel and i directly 
address the screen from an userland API. Somebody has a better solution ?

In my point of view a usermode api that access to ipod-hardware is bad 
but easier than doing fully Posix-Apm-fb-compilant.

What is yours opinions ?

What about doing a complete ipod-API for all hardware access (for 
individual components sleep mode, get/set processor speed, screen 
access, timer, keypad. As far as i know their is no protected-mode
in uClinux so their is no problem to do this.

Cheers,
Damien Marchal.

[Ipodlinux-devel] cvs updates

[Bernard L. <le...@bo...>]

Hi all,

I've just completed the first cut at migrating to the 2.4.24 kernel
(uClinux version) and my latest changes are now in CVS [1].

Sofar it seems everything works at least as it did in 2.4.20!  Firewire
is working (on my 2nd gen iPod at least) for tcp/ip [2] and almost
working for sbp2.  New in this version of the kernel is support for HFS+
filesystems.  I haven't tried it but this should allow you to run on Mac
iPods without conversion to FAT32.

If anyone wants to try this on a g3 iPod I would be interested to hear
how it goes.  There are some conditional compilations in the firewire
driver arch/armnommu/mach-ipod/tsb42aa82.c which may get it to work.

I hope to do a bit more testing over the next few weeks and then see
about putting up a new version on sourceforge.

cheers,
bern.

[1] The changes in the public cvs server may take some time to show up.
[2] The iPod driver still has problems with broadcast writes, this means
you need to modify the PC side drivers to not send broadcasts.  Put an
#if 0 around the code in nodemgr_do_irm_duties() in nodemgr.c.

[Ipodlinux-devel] 3g

[Martino di F. <web...@ma...>]

ok, moved a further steps toward (thanks bernard!!)
now i have another problem.
i've installed the bootloader with apple's firmware as default.
it loads without problems (apple logo, black screen, tux and then i get in), 
and i can use the ipod as usually. but, when i try to load the linux image, 
holding down rew at ipod start, it stops at the black screen before the tux 
image. i think it's a problem of the kernel, but before trying to recompile 
in some other way, i wondered if anyone has a hint.

thanks, bye

Re: [Ipodlinux-devel] Problem patching the firmware

[Bernard L. <le...@bo...>]

That output looks ok.  The "master image" is the default boot image
which is why it has the same as the apple firmware.  If you specified
the linux firmware first on the command line then it would become the
master.

Regarding your problem.  If you see the Folder icon on startup then the
bootloader was unable to start the image on disk which in turn means
that you must have modified it with the dd.

If you have mixed up 1.2 and 2.1 then this could be your problem.

Try restoring your iPod to its original firmware and make sure it boots
properly into the normal Apple OS.  Then once that is working try
following the bootloader instructions using a new backup from your
working iPod.  Other g3 users have had success so it definitely works ;)

cheers,
bern.

I am new to the list, and I know this is slightly off topic, but I am also

Another thing.

root@matrix87:~/dat/ipodloader-src-0.3# ./make_fw -v -o my_sw.bin -i apple_sw.bin -l /usr/src/linux/linux.bin loader.bin
Apple image added: type: '!ATAsoso' id: 0x6f736f73 len: 0x3194f4 addr: 0x28000000 vers: 0x     210

is there something wrong with that?
i did not understand completely the code of make_fw.c, but is it right that 
the apple image and the master image have the same devOffset? and why
loadAddr of all images are 0xFFFFFFFF?
thanks, bye

Re: [Ipodlinux-devel] Problem patching the firmware

[Martino di F. <web...@ma...>]

Hi Bernard, thanks for your answer.

I understood that 3g aren't yet supported, but i think i have a problem before 
loading the kernel. In fact, the bootloader when installed should show the 
tux image, and then decide which image to load. After i copy the image 
prepared by the bootloader, i see the apple logo, not tux, and then i get the 
broken folder icon, also with the 2.1 obviously because the linux root does 
not deal with the normal folder structure. I think that some offsets in the 
firmware are changed from previous ipods, and writing that image on the first 
partition does not overwrite the boot section so it's totally useless.
It's only an idea obviously, but i cannot explain in other way the fact that 
overwriting the firmware does nothing.

I'll try some more.

Re: [Ipodlinux-devel] Problem patching the firmware

[Bernard L. <le...@bo...>]

Hi Martino,

The 3rd gen iPods aren't fully working yet.  Take a look at the mail
archives on sourceforge for more details.

Basically though if you use the new bootloader you can use your existing
2.1 firmware (you are getting the broken folder icon b/c you downgraded
to 1.2 so you need to switch back to 2.1).

cheers,
bern.

I have a 3rd generation ipod, with firmware 2.1.

the 1.2.2 firmware and installed it from windows. Then i prepared the kerne=

Re: [Ipodlinux-devel] Bootloader

[Bernard L. <le...@bo...>]

Regarding the inital problem, the shell that starts up if the rc script has
errors seems to get the keystrokes ok so my best guess is that you don't have
the right standard input.  Perhaps if you open /dev/console explicitly?

Also you might want to take advantage of the 5 images from the bootloader. 
Come up with 5 test programs and simply put them all on.  Then select each one
using the bootloader keys.

Jim, seems you missed the announcement ;)

There is now a simple bootloader that will allow you to selectively boot one
of 5 images on your iPod.  Generally this would be the Linux kernel and the
Apple OS.  Take a look at the mailing list archive and/or website for more info.

As for the debugger, patching the binary to get something attached to the
timer IRQ or something probably wouldn't be too hard but I'm not sure what
help this would be.

Most of the information I need is about how the hardware works and that can be
analysed statically.

cheers,
bern.

   Has there been any progress making a bootloader that would allow you 
to relatively easily switch between Linux and the Apple Pixo OS?

   An even more improbably possibility comes to mind: would it be 
possible to put some kind of resident debugger (memory dump, register 
dump) in memory, then start up the Apple Pixo OS, while the debugger 
program is still active?  This would allow us a way to probe how the 
Pixo OS is set up.  It's a damn shame they don't have any DDK's with 
full symbolic information on the ROM, like they did with the Newton..

[Ipodlinux-devel] keypad access...

[Damien M. <ma...@la...>]

hi,

i'm spending some time to play with ipod-linux. As i only have usb and
i'm bored to reboot after each test, i'm doing a little shell
interface and i want to  use the ipod-wheel in my program.

I tried with getchar() but it doesn't work, next i try next with a
keypressed()-readkey scheme without success.

Someone has an idea ?

Cheers, 
Miencho.

Re: [Ipodlinux-devel] Linux on iPod mini

[Bernard L. <le...@bo...>]

Not really sure.

Anyone have any info on the hardware in the Mini?  I haven't seen a
disassembly yet.  It seems the HDD is different but that is unlikely to
cause any problems.  The smaller screen will probably make it a bit
quirky.

It seems they still have similar firmware (diagnostic/diskmode all seem
to work the same).

The firewire problem seen in the 3g iPods will probably still be there.

Anyone have one to try?

cheers,
bern.

Not likely with the current keyboards as they are also USB "clients" so
you'd end up plugging a client into a client :(

Re: [Ipodlinux-devel] Re: Firewire

[Bernard L. <le...@bo...>]

Hi David,

That is the correct hac^h^h^hpatch.

One thing to check is the node addresses of the iPod and your PC.  They
need to be 01 and 00 or it likely won't work.

cheers,

[Ipodlinux-devel] Linux on iPod mini

[Robert D <ro...@op...>]

 I dunno, but personally i see no point in the ipod mini. My ipod is small
 enough for me and i dont know what i would do with such a small HDD.

 I might do a quick google later on and investigate what is in an ipod mini.
