Can HBC even boot Kernel ELFs? I thought that BootMii had to be used? (I had
to use BootMii when i had Whiite installed)

Also, Please post updates on your progress, I am interested in porting
Android to the Wii but dont know enough about the kernels to download and
patch them. I learn by observing mostly, :)

<br>
I&#39;m trying to bring the recent Debian Squeeze on my new 2nd hand Wii.<b=
r>
<br>
The mikep5 kernel from 2009 loaded via the homebrew channel and does a<br>
wonderful job. I like to be more flexible with initramfs and<br>
theoretically have access to all squeeze features form their kernel<br>
(2.6.32+debianpatches).<br>
<br>
I had some success in crosscompiling ppc kernels on my amd64 box in the<br>
following variants:<br>
<br>
A) Debian kernel sources + Debian patches + mikep5 patch<br>
B) Debian kernel sources + Debian patches + wii backports from 2.6.38<br>
<br>
Now I tried to boot the two kernels via HBC, but it gives an error<br>
message, telling me, that this is not a Wii application.<br>
<br>
The file-tool indeed gives different outputs [1].<br>
<br>
The question is, how to create a bootable elf kernel for the wii?<br>
Or a bit more precise, what (ELF-)format does the HBC expect?<br>
<br>
<br>
Basically I followed the instructions in the wiki [2]. But I used the<br>
the Debian make-kpkg tool to create whole debs and extracted the kernel<br>
image afterwards from this deb. The options for make-kpkg [3] are nearly<br=
>
the same as those listed in wiki:<br>
--initrd --cross-compile powerc-linux-gnu- --arch powerpc kernel_image<br>
--append-to-version [...]<br>
<br>
One need to know, that I didn&#39;t use the devKitPPC-cross toolchain, but<=
br>
the on-board Emdebian crosstoolchain from squeeze (Debian 4.4.5-8).<br>
<br>
Maybe someone on the list knows, what to do to create the appropriate<br>
ELF format or run into the same traps?<br>
<br>
Many thanks for any hint and/or comment.<br>
<br>
Best regards,<br>
