[Ipodlinux-devel] Framebuffer and mmap()

[<dj...@ca...>]

HI=2E

I am working with 2 other OS students on either porting or designing a GUI f=
or the iPod and today we successfully booted our iPod with the Linux kernel(=
yeah!!!)=2E Currently, we are trying to figure out what exactly does not wor=
k with the mmap() call that writes to the framebuffer=2E From what I read on=
 the ipodlinux site, this would limit the use of X Windows=2E So my question=
s are =2E=2E=2E

- Should we look into hacking mmap() so that it will function properly with =
the framebuffer? Or is there a workaround to this problem that we as NEWBIES=
 are not aware off?

- How much will the framebuffer issues affect us if we try to design our own=
 GUI?

- Bernard mentioned looking into alternatives like porting MicroWindows or G=
TK++, how could we get started on this?

- I looked at the fbcon=2Ec and fbmem=2Ec files in the CVS tree =2E=2E=2E am=
 I on the right track?

Any technical suggestions would be great!

Thanx=2E

Hi!

I've got my ipod yesterday... I've just compiled a kernel with firewire
support to try playing with it from linux.

Ok, thanks. I will try this in the weekend if everything goes well.

Ok, I'll try this next week - I don't have a scope at home :(

I couldn't find it now. But IIRC I've seen one a a month ago or so, they
said that the circuit inside the remote was the same, only the connector
changed. But it would be nice if I knew the layout of at least the known
pins on the connector.

Ok, then my feeling about the normal SDRAM being slow was correct. Then
still, we should look into the DSP tremor project and find out, how much
memory they need, etc. I'll try this when the basic hardware is running.

Apologies, I thought gmane (note previous typo) was already archiving
this list but it doesn't look like it is.  Now might be a good time to
start ...

There must be some way to pull out of the gmame archive to mbox format
via NNTP.  Does fetchnews do it?

Re: [Ipodlinux-devel] new ipod, etc

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

Hi Dani,

Its great to see some revived interested in the project.  Unfortunately
my time is fairly limited but I'm willing to try and help out where ever
possible.

Reviving the initrd may indeed be a good plan - unfortunately I don't
have any of the old code hanging around.  It should be quite easy to get
going though as there are a number of examples with the other uClinux
targets using it.  The full uClinux "distribution" build has a mechanism
to automatically build the disk image.

>From what I remember there actually isn't much more required than whats
in the head-arm-ipod.S.  Once you enable the compile option I think the
rest of the code just switches on...

As for the serial stuff doing it in the kernel may be kinda hard...
however the ipod serial driver is already working so in theory if you
just started up a console on the right tty line it would all work!  I
assume the g2 hardware has one of the UARTs IN line connected up for the
remote control.  I would assume the g3 has the OUT line for the same
UART connected up (the other UART is used for the piezo).  Unfortunately
I have no idea what pin on the connector might be used (is there a
dissection out there somewhere??).

Other thoughts; yes the CPU is speced to go up to at least 90MHz. 
Cranking it up doesn't really improve performance as the problem is more
that the memory is not fast enough.  The 96KB of on chip ram _is_ fast
enough and that does help.  The problem is getting balance right between
putting code/data in the fast ram and then splitting the workload
between the two cpu cores.

The SRAM starts at 0x28000000 the on board ram is 0x40000000.

Sorry I don't have a mbox archive and it doesnt seem the mailing list
software will spit one out...

cheers,
bern.

Re: [Ipodlinux-devel] How to poweroff the iPod ?

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

Hi Gilles,

Unfortunately you can't.  The closest you can do is to boot to disk-mode
which may use a little less power than in Linux mode...  The current CVS
version will power down the LCD after some time to reduce the power
drain.

Note, the normal iPod firmware implements the "power off" as a suspend
function so its not a true power off.

cheers,
bern.

[Ipodlinux-devel] How to poweroff the iPod ?

[Gilles Boccon-G. <bo...@bo...>]

I've decided to start experimenting with Linux on my iPod. I've 
installed the kernel and root fs, but now I'm stuck with a small 
problem: how to I switch off the device ? Holding "menu" and "pause" for 
5 seconds allows a reboot, but is there a key combination for force a 
poweroff ?

[Ipodlinux-devel] new ipod, etc

[PALFFY D. <dp...@ra...>]

Hi,

It seems like the ipodlinux development has slowed down a bit last
months... I think it would be nice to accelerate it, since I'll reveive my
new g3 ipod this week.

I really want to get the kernel running on the new ipods and i will try to
do it to my best knowledge, but since I haven't done much low level kernel
programming, any help would be appreciated.

I think the first two steps would be to revive initrd support and to look
if one of the new remote pins was connected to a serial output (I can
easily imagine a bigger remote with an LCD display as a future accessory).

About the initrd part: Bern, do you have any of the early versions running
from initrd? The CVS tree at sourceforge doesn't seem to contain anything
except the stub in head-arm-ipod.S.

About the serial ports: What should I try to get some 01010101 out on the
serial port that I can look for with a scope? If I could boot to an initrd
it would be easy, but I haven't ever tried kernel space serial
programming... Or should I write a short assembly routine and boot to it
directly?

And some other thoughts:

The current code sets the processor speed to 75MHz, but, according to the
specs it should support 90. This increment should help somewhat in vorbis
and mp3 decoding.

Also, the 96Kb of on-chip SRAM could help. The current development of
tremor to support DSPs is trying to reduce memory footprint - so if we
could squeeze as much of the critical code into SRAM as possible might
help a lot, especially because the main memory seems slooowwww if it only
has a 16 bit bus. The slight overhead in CPU cycles should not matter,
someone on the tremor development list claimed that a 30-40 MHz ARM should
be able to decode vorbis if it had enough fast RAM. By the way, I couldn't
find much about the memory map of the iPods. Where is the SRAM memory
located?

Thanks in advance for any help.

Re: [Ipodlinux-devel] linux on the new ipods...

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

Hi Bruce,

Before I had IDE up and running I used a initrd to get things going.  It
was a long time ago and it was a bit temperamental then so I imagine the
bit-rot hasnt helped.

Anyhow if you take a look at head-arm-ipod.S, at the end there is an
.incbin that I used to include the initrd into the binary.  If you poke
around for for the CONFIG_BLK_DEV_RAM you should find some other parts
which need to be modified as well.

As for building an initrd I used the full uclinux distree and it builds
one ready to go...

cheers,
bern.

Re: [Ipodlinux-devel] Linux Firmware and MP3 Playing

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

Unfortunately there is still no dual boot.  I was trying to get a tool
that could start the retail firmware from Linux but gave up in the
attempt.  A simple boot loader would probably be better anyhow... does
anyone know of a simple boot loader suitable for porting?

The current Linux port really isn't up to running full time as a MP3
player.  It has a couple of problems not the least of which is that
there is no application with a UI for playing stuff.  The fact that the
MP3 decoding is not full speed could also be seen as a show stopper :)

The decoding speed could be improved, its just a matter of getting in
there and finding out what to fix.  Unfortunately the iPod (at least the
2nd gen retail version) is a real pain to debug with so its quite slow
going.  Patches welcomed...

Hmmm as for turning it into a Newton, sounds like fun.. not! :)  The
Portalplayer chip actually has an IDE controller on board as well as
support for various removable media (see
http://www.portalplayer.com/products/products_01.htm).

cheers,
bern.

Re: [Ipodlinux-devel] which compact flash reader?

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

Hi Larry,

I have both a Sandisk and an Lexar reader.  The sandisk was not working
under Linux (last time I checked...) and the Lexar needs a powered hub
or a gender converter as it has a fixed cable (I only have a
firejuice).  I just picked up a firewire disk enclosure so I'm hoping to
give that a go with the iPod (unfortunately it seems the manufacturer
was too cheap to power the second port on it so I still can't try the
Lexar).

The Firejuice + sandisk combo works well except that the reader wasn't
(isn't??) supported by the Linux ieee1394 drivers.  I was also seeing
problems with the iPod firewire driver but that may have just been
problems due to the lack of support under Linux anyhow.  The nice thing
about the Firejuice is you can power it from the Apple charger which you
would have with you on the go anyhow.

cheers,
bern.

[Ipodlinux-devel] Re: Linux Firmware and MP3 Playing

[Jim W. <js...@bl...>]

   Doesn't the iPod have a hardware MP3 decoder (/encoder?) chip in it?  
Can it be accessed yet from Linux?

   By "isn't very useful" - what exactly does this mean?  Are we talking 
realtime decoding of full 320bps, 16-bit, 44KhZ, stereo MP3s.  Because 
I've got an MP3 player on the Newton (169 KHz StrongARM or whatever the 
clock speed is) that runs pretty decently with MP3s of 80bps, mono, 
8bit.  I'm told it'll go up to 128 and not choke much.  The main 
bottleneck is probably the Newton's low-level memory system (it doesn't 
seem to like to deal with big VBOs on the stores).  But the iPod's got 
TWO ARMs (hmm, interesting pun..), so could MP3 decoding just be 
shunted to the "back" processor" while everything else goes on on the 
front one?  Do we know how to access both processors and get some kind 
of MP working?

   I guess for the really daring, an interesting experiment would be to 
try to plug a CF reader or whatever directly into the PCMCIA CardBus 
that the hard drive is on.

   (The just hook  it up with two open slots, rearrange the electronics 
to fit in a sligtly bigger case, but a bigger grayscale screen on it

I don't have a firejuice, but looking at the website, it would seem that they
just expose the power wires on the cable to an external power source while
passing the data wires straight through. It seems they also provide switches
so you can power one, both or neither device.

A powered hub has a power supply and some electronics to act as a repeater on
the bus. It looks like the firejuice has no power supply (you provide your
own) and it certainly has minimal or no electronics, so it would be cheaper.

I would be interested in a compact flash card reader solution for the ipod.
However I was under the impression that the available linux firmware isn't
very useful as an mp3 player. Is it possible to dual boot the ipod? I wouldn't
want to go travelling without music just so I can store photos.

[Ipodlinux-devel] which compact flash reader?

[Larry L. <lli...@ya...>]

Bern or others,

what firewire compact flash reader would you
recommend?  i'd like to help implement CF reader
functionality into the ipod linux version.  i read in
one of Bern's earlier messages that his is
inconsistant under linux, anyone care to recommend a
brand?  current choices seem to be lexar and sandisk.

for power, what do people suggest?  firejuice or
powered hub, others?  i probably don't have time to
make a battery powered adapter.  how does the
firejuice setup work - the firejuice seems cheaper
than most powered hubs.

Hopefully someone can offer some suggestions.

Thanks,

Larry

I'm working on a GUI.

I'm using now gtk and developing it in my normal Linux environment, my
idea is just use a cross compiler when it has more functionality.

I have a basic menu stuff. I'm cloning the Apple interface, because I
think it's a good one.

To roll-back versions I have dd'ed the update directly onto the boot
disk (which is basically what the update program does anyhow...).  After
the dd reboot with the firewire power connected and it will do the
re-flashing.

Hi Antonio,

A GUI would be a nice project to work on (since sofar no-one else has
build anything...).  Another neat CS project would be building an
emulator that would let you run iPod applications on another host.

A good start would probably to use something like Microwindows.  That
would let you develop applications on desktop Linux machine and simply
port/test on the iPod.

As for HFS+, its recently made it into the 2.6 kernel so hopefully it
will "just work" when that is ported to the iPod.

I'm not sure what successes there have been from Mac users.  I know
there is a toolchain that works at least (links on the website).  The
main problem is the HFS+ support.

cheers,

[Ipodlinux-devel] Re: OS Class Project

[Jim W. <js...@bl...>]

Hi,

I'm not actively involved in the iPodLinux development, ju...
lurker..  A GUI would be good, although an HFS+ driver wou...
be more useful for the larger community (and probably easi...
drivers surely already exist for other Linuxes, and Darwin
certainly.)

    But you mentioned the hope of eventually being able to manipulate the
pitch.  This would be very interesting, as it would mean running
another task simultaneously with the Apple Pixo OS.  I'm not sure how
you'd do it, as it would need to either buffer sound samples and "take
over" the sound output chip input, or change the way the Pixo software
interprets the MP3 data, or more likely, intercept the data and decode
it yourself.

    In any case, this would allow a framework for getting custom programs
running in parallel with the Pixo OS, and interacting with it.  This
might require Apple's help, which is unlikely to come (though there's
small hope).  I'm involved in a group of about 7 deciphering how the
Newton OS works, but I very much doubt that the structure of how tasks
on the NewtonOS is organized is anything similar to how it's done on
the iPod.

    Though if someone could get their hands on documentation for Pixo
(and not have to go under NDA to do it)..

Re: [Ipodlinux-devel] linux a good alternative...

[Antonio Y. N. <dj...@ca...>]

( hfs++ is a good idea) I agree, since most iPod users (including me) 
use Mac OS X. How could this be done?

Another hurdle I've run into and have been trying to solve since last 
night is updating the software on my iPod to an older version (Updater 
1.2.2). I have the installer but it does not let me continue since it 
registers a newer version of the software.

Has anyone found a solution for this?

Thanx in advance!

[Ipodlinux-devel] linux a good alternative...

[c\.bisegni\@inwind\.it <c.b...@in...>]

I'll also think that a support for hfs++ is a good idea, because if there=
 is a good release of al linux os for ipod and a good little xserver i th=
ink that ipod will give as much music program and contact managing opport=

[Ipodlinux-devel] OS Class Project ...

[Antonio Y. N. <dj...@ca...>]

HI, I'm currently taking an Operating Systems course for my CS degree 
and am looking for a semester long project that will be developed by a 
team of CS students. I am interested in working on creating a GUI for 
the IPod that will run over the iPod/linux port under development, with 
high hopes of eventually being able to write an application that 
manipulates the speed and/or pitch of songs playing off the iPod (I'm 
into DJing too). I've read through the website and it seems you guys 
have developed some good stuff ...

In other words, how possible is this (GUI for iPod) endeavour? Would a 
better choice be to add HFS+ compatibility?

Also, today I started the installation tutorial on the website to see 
if I can succesfully get the linux to port to run with my iPod (5 gig) 
from a MAC. I read somewhere that I was "on my own". Has anyone else 
managed to install it from Mac OS X?

Sincerely.

Re: [Ipodlinux-devel] Patching 1.40 firmware

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

Hi Domingo,

Unfortuantely the Linux port I have done does not run correctly on the
3rd generation iPods.  There are enough hardware differences to stop it
from booting.

If you're interested in trying to debug that would be great as I don't
have any 3g hardware.

cheers,
bern.

[Ipodlinux-devel] Patching 1.40 firmware

[Domingo A. <dal...@ar...>]

Hello. I'm trying to install linux on my third generation ipod. It comes =
with=20
firmware v1.40.

What have I to do to patch the kernel ELF with this firmware?

Can I downgrade my firmware to a 1.2x version? I have tried to install so=
me=20
1.2x firmware and my iPod does not boot!

I would like to install linux on my iPod to make some app's. I have some =
OS=20
and low-level knowledgement and believe that I can help to make a real=20
firmware replacement with linux.

Thanks in advance.
Domingo
