Dear ,
I used a platform called "migo-R" which cpu is SH7722.
http://tw.renesas.com/fmwk.jsp?cnt=sh7722_root.jsp&fp=/products/mpumcu/superh_family/sh7780_series/sh7722_group/
I download a android kernel source "linux-2.6.25-android-1.0_r1.tar.gz" from
"http://code.google.com/p/android/downloads/list";.
The toolchain is "gnush4-nofpu_linux_v0701-1.tar.gz".
http://www.superh-linux.org/platforms/index.html#sh7722migor
(step 1).
I set up "NFS" from migo-R to the Host PC.
(step 2).
Generate the default .config for the kernel using the migor_default config
,the config
file found /kernel/arch/sh/configs/migot_defconfig (ARCH is case
sensitive)
--> make migor_defconfig ARCH=sh
(step 3).
When I complier the kenel, it will be something wrong. The "binder" source
code
seems to be lacked some file,so I modify the binder to module<M> in the
kernel.
Then it continues to complier to generate uImage.
(step 4).
I use the U-boot to start the uImage.

Failed to execute /init. Attempting defaults...
Kernel panic - not syncing: No init found. Try passing init= option
to kernel.
(step 5).
I check to file system.
The download source is :www.androidin.com/bbs/pub/armv4.tar.gz
The NFS can't connect to Android file system.
I check the init, it seems only for ARM .
So the console message shows -->
" Failed to execute /init. Attempting defaults...
Kernel panic - not syncing: No init found. Try passing init= option
to kernel. "
[r...@mirl194052 rootfs]# file init
init: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically
linked, stripped
The questions are
(1) Do I have do something error ?,
(2) Is the init for ARM cpu, not for SuperH cpu?
(3) How to generate the init file for superH?
(4) Is Android supported the SH-MobileR(sh7722)?
