Hi guys!
I'm trying to run Android on an Atmel AT91SAM9261. After compiling the
kernel and building Android with the Google Toolchain, I created a
jffs2 image and flashed it onto the CPU.
Then I tried to boot with
"root=/dev/mtdblock0 rw rootfstype=jffs2 console=ttyS0,115200 ip=off
lep9261-bl.brightness=90 noinitrd mem=32M init=/init"
but this stops after
"VFS: Mounted root (jffs2 filesystem).
Freeing init memory: 500K"
As this is the point where init should start, I tried to boot with
init=/system/bin/sh, which gives me a small shell. If I try to run /
init from in there I just get a Segmentation Fault.
strace /init is giving a lot of output like:

Has anybody got ideas where the problem is? Seems like wrong
executable format or something like this to me. I also tried to
compile with another toolchain (codesourcery), but still having the
same problem.
