Hi, I've been able to install the kernel, but I am having issues installing the file system. I am using the m5-rc14 userspace with the m5-rc14 kernel.

I get a segmentation fault upon running the kernel. I straced the init and received:

I can't seem to figure out what's going wrong. Any ideas?

Hi, Please ignore it. It is caused by the wrong file system. Keep working on the blank screen issue.

Hi, I use the toolchain(cs2005q3.2-glibc2.5)
inhttp://www.progbox.co.uk/wordpress/?p=453. But I got the following error in /dev/log/main:

dalvikvmToo many exceptions during init (failed on 'java/lang/ NoClassDefFoundError' 'java/lang/NoClassDefFoundError') dalvikvmVM aborting le deps in cache file; removing and retrying dalvikvmDexOpt: --- BEGIN 'core.jar' (bootstrap=1) --- dalvikvmDexOpt: waiting for verify+opt, pid=1688 dalvikvmDexOpt: --- END 'core.jar' --- status=0x0009, process failed dalvikvmUnable to extract+optimize DEX from '/system/framework/ core.jar' dalvikvmDexOpt: incorrect opt magic number (0xff ff ff ff)

Not sure whether it was caused by the toolchain. Should I use cs2007q3-glibc2.5 to compile the source ?

Thanks, Leon

I can't believe it !!! Android runs on the maemo n810 !!!

After reading
this:http://groups.google.lu/group/android-internals/browse_thread/thread/... for the 100th time, and following the instructions on the mentioned link:http://nemustech.blogspot.com/2007/12/android-porting-to-real-target-... it works.

Here are the specifics I've implemented: * patch /etc/init.rc ---- begin : init.rc .... ## qemu-init { ## exec /etc/qemu-init.sh ## } network-property { exec /etc/set_network.sh

}

/bin/chmod -R a+rw /data /tmp /bin/chmod a+rw . /bin/chmod -R a+rw data

# rm /dev/log (if you have) # mkdir /dev/log;touch /dev/log/{main,events,radio} * you can see usefull infos from strace log and /dev/log/main

and instead of: chroot . /a.sh I execute the android init process: chroot . /init

Not sure yet what exactly of those steps solved the problem (maybe the qemu one), but it does work. After a quick try I see that the touchscreen doesn't work (the keyboard does though), but that shouldn't be too hard to fix.

BTW, this is using an m5 kernel, and binder.c
