[Ipodlinux-devel] ipodloader on ppc

[Steven L. <sl...@uc...>]

Hey everyone,

I haven't been around these parts for a while, but I'm trying to catch up
with everything that's been done.  I'm running into two independent problems:

One is with the ipodloader.  I'm running gentoo on ppc with a g1 ipod.  Once
I change the "char c" to "int c" so the thing doesn't get stuck in the loop
(line 260), it appears to make make_fw alright.  For the cross-compiled
stuff, however, I get the following error:

"
arm-uclibc-gcc -Wl,-Tarm_elf_40.x -nostartfiles -o loader startup.o loader.o tools.o tux.o
/home/local/uclibc/bin/../lib/gcc-lib/arm-linux/3.2.1/../../../../arm-linux/bin/ld.real:
loader: Not enough room for program headers, try linking with -N
/home/local/uclibc/bin/../lib/gcc-lib/arm-linux/3.2.1/../../../../arm-linux/bin/ld.real:
final link failed: Bad value
collect2: ld returned 1 exit status
make: *** [loader] Error 1
"

If I add -N to LDFLAGS in Makefile, everything compiles nicely, but when I
follow the instructions in the README I just get a "folder!" icon when I try
to boot my ipod.  I don't know if the -N is the culprit (not very familiar
with linking), or if it's something else (endian problem?).  Is there a newer
(CVS?) copy I could get my hands on?  Is anyone else experiencing these
problems and I just missed the message?

The second problem comes when trying to compile the kernel.  Actually, it's
before I even get to that point.  After I "make oldconfig", I "make dep" but
get the following error:

"
make[6]: Leaving directory `/home/uc/linux-2.4.20/drivers/video/aty'
make -C intel fastdep
make: *** intel: No such file or directory.  Stop.
"

I didn't used to get that message when cross compiling a kernel for the ipod,
so perhaps it's one of the new patches?

Thanks for any help,
Steven

Hi Steven,

Sorry about the ppc bug, I think it was you that reported it some time ago...
Its been fixed in cvs but not in the release version.  The CVS version also
has an endian fix for the extraction code so you probably should grab the cvs
version for now.  This bug may be the cause of the folder icon.

The other problems you are seeing I would guess to be related to the build
tools you are using.  I'm not sure where you can get a prebuild ppc-arm cross
compiler but perhaps you could grab the source distribution from uclinux and
build that?

cheers,
bern.

[Diman T. <dim...@ri...>]

if you still dual boot with macosx... there is a precompiled arm gcc on  
applie.com (go figure :)
also www.handhelds.org provides a lot of information on arm cross  
compiling toolchains
i am afraid though they only have precompiled ones for x86
doesnt debian have a precompiled ppc arm cross compiler? just a guess

regards
diman

Re: [Ipodlinux-devel] ipodloader on ppc

[Steven L. <sl...@uc...>]

Hi,

I grabbed the CVS version and the bootloader now works.  I still had to add
-N to LDFLAGS, but the ipod shows tux and I can choose which OS with the
buttons.  The bootloader is very handy:)

I'll work on the kernel issues later tonight.  (I tried both the 2.95 and
3.2.1 toolchain built from the uclinux source).

Thanks,
Steven
