Hi Jonathan,
sounds like you're making some really good progress there! It would be really
neat if we could get libmad decoding at full speed. The big win there will
probably be if we can move some of the data that is accessed frequently into
the on-chip ram. The only question is which data to move. Currently the
onchip ram is used as a circular buffer for buffering data that is to be
written to the DAC (the CPU is a produced and the COP a consumer on this
buffer). At the moment it is using the entire 96K for that purpose so if that
were reduced then some could be used by the user process. (E.g. just create a
pointer to 0x40000000 somewhere ;)).
Regarding the big malloc problem that is a little strange. The patches in the
mp3example player malloc up a chunk large enough for the entire file so you
can definitely malloc more than 512 bytes. The uclinux 2.4 has a special slab
allocator (non power of 2 version) which we use to allow big mallocs. (Sofar
2.6 doesn't have one so I'm not sure what the plan there is).
In /proc are some files which can give you some status on the memory
subsystem. I can't remember their exact names but they should be fairly obvious.
As for the -ipod0 and ftp problems the default ip address changed to
192.168.222.2, maybe that is causing you some problems?
Anyhow looking forward to seeing some of your patches ;)
cheers
bern.

Forgive me if I'm mistaken about what you're trying to do, but would it not be possible simply to get the songs chosen for play, and attempt to allocate memory per song, and just retain a list of where these songs are in memory and then point to those for playing? It seems sort of strange that you're trying to re-implement something that's technically built into the memory manager. If there is no contiguous block large enough to hold the mp3 then you could attempt to split, and store half in one part half in another, and continue to split until it does fit... just an idea.

Hi Bernard et. al.,
As mentioned before on the mailing list, I am working on a play
queue/multi song buffer, and incorporating mp3 playback into podzilla.
In the process, I have run into a problem with memory management. After
coding and testing on the host (works great with libmad!) I
cross-compiled and installed the app on my iPod. Upon initialisation I
allocate 16M for the buffer, but this fails on the iPod. (Okay, I
probably need to allocate several blocks instead of one chunk, because
there is definately more than 20 M free, albeit not contiguous.) I then
wrote a simple-minded programme to probe the maximum amount of
contiguous memory:
int main()
{
int bytes = 1;
char* buffer;
while (buffer = (char*) malloc(bytes * sizeof(char))) {
free(buffer);
printf ("success with %d bytes\n", bytes);
bytes <<=1;
}
return 1;
}
The app hangs after 64-512 bytes, with endless errors scrolling by on
the lcd display, too fast to read. I am invoking the app via telnet
with the 2.4.24-ipod0 kernel. I have not tried it standalone. As there
are examples of malloc in existing code, I can only presume that there
is a problem with free(), or that I am missing the point entirely... (I
haven't coded plain c in a couple of years).
Anbody else seen this behaviour? If not, any pointers as to how I can
debug it? (Slowing down the console messages would be a start!)
A quick update on my progress: I have built a standalone libmad app with
console input (play/pause/quit) and with a modest (1 song) buffer (using
mmap). This works fine on the iPod, except of course that it is not
100% real time... (a couple of tweaks in the configuration of libmad did
improve matters drastically though! I still have hope...). Otherwise,
I have built a circular buffer for multiple-track caching into
Podzilla. Playback is incorporated into the main loop by decoding a
single frame in between each successive poll of the event loop.
As soon as I have sorted out the allocation problems and tidied up the
code a little, I will post my patches.
Thanks,
Jonathan.
P.S. since I upgraded to the ipod0 kernel, I have not been able to ftp
-p 192.10.1.1 anymore. Anyone know what's going on there?

Hi all, Attached is an updated loader.bin which I believe resolves the problem people are seeing with the lockups in the Apple firmware. Unfortunately I can't reproduce it on my iPods so if people with the problem could give this a try that would be great. Simply replace the loader.bin in the existing release, re-create your firmware image with make_fw and install to your iPod. thanks, bern.

Finally decided to install linux on my iPod after following this project = for a while. Everything went surprisingly well, with both linux and the = apple os's working well. The problem came when I rebooted into XP, which told me that my iPod was = not formatted so couldnt be used...! In linux I can mount sda3 fine, and sda2 sometimes (often redhat 9 hangs = at this point or soon after, which it never used to do). Has anyone else had this problem before? Maybe I should dd the original firmware back on and see if that fixes = things... Jeff |

Ok The thing is, the module has to be built for your excact kernel... Your best choice would be to download a kernel-source package from fedora= , =20 and configure and compile that yourself. After that the ipodeth module =20 should build without any problems. Then copy the module (ipodeth1394.ko) = =20 to /lib/modules/<your version>/kernel/drivers/iee1394 and run depmod. Alternatively, you could try to download the kernel-headers package for =20 your kernel, and see if you can get the module to compile with that. I =20 tried that with no luck in Debian linux, however.

Hi Lucas, Thanks for the confirmation. My guess is that the extra time taken to relocate the Apple firmware (which happens only when it is not the default) ensures that the race condition does not occur. I hope to get a chance to test this on the weekend and if all goes well will hopefully sort out a fix then. cheers, bern.

Hi Ronja, Are you saying that it works when the Linux firmware is the default but not when the Apple firmware is? Is it readily reproducible on your iPod? What model is your iPod? It looks like there is a race condition during the startup, I think I have it worked out but no coded solution yet. Hopefully I can reproduce the problem so I can test a fix. cheers, bern.

Ive gotten through my first round of problems with a factory restore. My ipod is now succssesfully booting into linux and back to the original firmware. However now my music won't play. When I try to play from the regular firmware, it just waits a couple of secs and then reboots. When i try to play from podzilla, i can't even open the browse menu. I plugged it into my mac and opened itunes, all of the music was grayed out and unplayable. Any pointers would be greatly appreciated. ---- Msg sent via Spymac Mail - http://www.spymac.com |

Version 0.3 adds functionality to _update_ certain entries. In other words not the whole db is rewritten but only the parts that actually changed. Currently functions to change the playcount, last_played and rating entries are implemented. Apart from that the callback API chaged slightly. The user can now pass data to the callbacks. The tarball can be found at: http://www-users.rwth-aachen.de/jens.taprogge/files/libitunesdb_0.3.tar.gz Best Regards Jens -- Jens Taprogge |

I don't remember the version of autoconf, but I am using automake 1.7.=20 Using the newest Debian unstable packages for both. I'll check it next=20 time I boot into linux. If you have the build environment set up for compiling arm-binaries,=20 please feel free to send me a binary and I'll see how it performs on the=20 pod. Terje |

And I will likely not find the time until the week after next week. I would certainly like to know if/how well it runs on the ipod. There might be endianess problems in two places. But that should be fixable easyly. One way to optimize for ipod use it to only parse the information the ipod uses or is going to use (most likely Artist, Album, Track Name, Track Number, Volume Adjust, Playcount, Rating, Genre). That would save us the UTF conversion etc. I have been thinking about adding that. A rough estimate is that it would increase performance by about Bernard: I guess using mmap is not an option on the ipod since it does not have a full scale MMU? > I have tried to build your program, but the ./configure script fails with: > checking how to run the C++ preprocessor... /lib/cpp > configure: error: C++ preprocessor "/lib/cpp" fails sanity check > I guess I'm missing some package. This is the first time I have done an autotools package. So it is not unlikely something is broken in that regard. What version of the autotools programs are you using? (I am using autoconf 2.59, automake 1.7.9) Here it says: checking how to run the C++ preprocessor... g++ -E You might also want to try setting the C++ preprocessor manually by specifying CXXCPP (see configure --help). > Anyway, good work, I'll probably discontinue work on the port if your > library turns out to be more efficient =) Thanks. I think a native implementation is preferable. (That's why I ended up coding it.) It should be quite fast. There also is still room for improvement (by inlining certain functions that are only used once etc.). But for now I want the implementation to be correct and clean in the first place. Adding playlist support should be easy. Perhaps we can join our efforts. If the project is appreciated by the other developers I will put it in CVS on sf.org. > Terje > > PS: Funny that we both ended up using the same UTF conversion functions =) Well, I have actually taken a look on your port. And than figures that the implementation by unicode.org should be the most reliable. Also the api did fit perfectly. Thank you very much for your feedback! Jens -- Jens Taprogge |

Hi Seems we are working on the same thing, basically =3D) I just finished my version 0.11 yesterday, downloadable from=20 http://orz.dyndns.org/stash/parsedb0.11.tar.gz , which parses the playlists as well as the tracks.

I know how to change the terminal mode to be noncanotical as well as how to turn off terminal echoing using POSIX functions. When I run the shell on my computer, it works without flaws. Unfortunately, when I run the same code on my iPod, turning off terminal echoing does not work and it does not seem that I can receive anything from the stdin stream in either canonical or noncanonical mode. If you have a program that can read what is typed on the iPod I would appreciate seeing the code. Jeff N.

What does everyone else think? Verision 0.2 of the library converts all strings to UTF8. It seems to be much more convinient that way, saves nearly 50% memory on the strings and does not add too much overhead.

For reading letters ( keys pushed ) on the ipod you will have to change the console mode, instead of reading after a return ( you only read letters after return is pushed ) you must put the console in a mode that reads character by character ( but you loose the return key and one key in the ipod is a lot ) I made a program that makes the same you try also for running podzilla >> On an unrelated note: >> Has anybody found a way to read what buttons the user >> has pressed on the >> ipod?
