I'm using vanilla Kernel 2.6.21.0 with the patch from

I was told in another thread that I need to use the m3 userspace
files, but when trying to use those, I have the same issue.
I'm assuming you want the strace when running init:

Mmh, there are some reports on this list with similar SIGSEGV:
http://marc.info/?l=linux-omap&m=120393103218574&w=2
http://marc.info/?l=linux-omap&m=120400327301855&w=2
http://marc.info/?l=linux-omap&m=120834030203728&w=2
But It doesn't look like the archives have a detailed solution for this.
Seems that changing some parameters (e.g. switching to other binder driver,
SDK etc.) made the error go away.
I'm CCing Anil and colorant, maybe they remember what helped.

Hi,
I'm trying to get android installed on an N810. I have successfully
installed the kernel,
Which kernel (2.6.x, x == ?) do you use on N810? If I remember
correctly,
with N810 people use an older kernel than the one coming with Android
SDK.
but I am having major issues with the file
system. I followed the tutorial you provided at
http://elinux.org/Android_on_OMAP, but I get a
segmentation fault when
I try to init the kernel. I made sure to use the same android SDK
version that was used to patch the kernel.
My steps for reproduction are:
1) On my computer, unpack the ramdisk image to a folder.
2) Untar system, dev, and data to the unpacked ramdisk image.
3) Tar up the patched file system and scp it to /opt on the device.
Ssh to the device and unpack the file system in /opt
4) Run umask 000 && chroot /opt/android /init
5) Receive a segmentation fault.
Can you send us the complete segementation fault output?
Regards
Dirk
