So titled because my problem is very similar in symptoms to the thread "Problem porting Android to OMAP". My port to the iPhone runs Debian and X.org with the multitouch screen, sound, WLAN and USB gadget ether net working fine. In order to maintain dual-boot capability, I put the Android images on one of the iPhone's partitions (which is HFS+ on top of Samsung's Whimory FTL on top of a few NAND chips) and I'm planning on booting Android from that. I built the images from a checkout with repo using the generic instructions from http://pdk.android.com. I set TARGET_USERIMAGES_USE_EXT2 in the environment so I get ext2 images. I created a 1 MB ext2 image to store the ramdisk files instead of using it as an actual initramfs. I modified the /init.rc to comment out the mtd mounts, since my code will be mounting /system, /data and /cache before Android's init is called.
Android's /init doesn't seem to care if it's PID 1 (I've observed from reading this mailing list), so I've been calling it from my busybox/buildroot ramdisk. However, it doesn't seem to work. After awhile, it will complain "init: critical process 'servicemanager' exited 4 times in 4 minutes" and will reboot. I commented out the "critical" specification for the servicemanager service in init.rc and ran /init under strace. You can see all the logs that resulted as well as the exact commands I performed here: http://iphwn.org/planetbeing/postmortem/ kernel-config.txt is my kernel configuration, in case there is some option I forgot to enable or some option I must not enable. My patches to kernel/common android-2.6.32 (done on commit e27f17b5318851395a66cbaf1524ea89ff8f0cb9) is also present in that directory if those are helpful. Finally, here's what df shows: # df Filesystem Size Used Available Use% Mounted on /dev/root 9.2M 8.1M 1.0M 89% / tmpfs 60.8M 96.0K 60.7M 0% /tmp /dev/nand0p2 14.4G 1.4G 13.0G 10% /mnt /dev/loop0 1003.0K 278.0K 674.0K 29% /android /dev/loop1 72.1M 52.2M 20.0M 72% /android/system /dev/loop2 193.7M 14.8M 168.9M 8% /android/data /dev/loop3 48.4M 810.0K 45.1M 2% /android/cache I think that's enough space for Android. /dev/loop0 is ramdisk.img. >From my analysis of the strace files, it seems as if servicemanager is being sent SIGKILL by an unknown murderer soon after it starts (http://iphwn.org/planetbeing/postmortem/strace.486.txt). None of Android's init or its children seem to be to blame from the strace outputs. Android's init DOES send a SIGKILL to servicemanager but only after it receives a notification that it has already died. There's no kernel messages (http://iphwn.org/planetbeing/postmortem/messages.txt) that indicate that some OOM killer is at work (unless Android's LOW_MEMORY_KILLER is utterly silent). I certainly did not kill the process myself. Ignore the stuff in messages.txt about the multitouch firmware requests. I didn't bother to send the firmware for that test but it doesn't make a difference if I load the firmware before running Android's init. I don't own an Android-capable phone so I can't even test whether the images produced by my build are sane at all. Anyone have any hints about what could be happening? Is there an alternate track I should be following? Thanks, David -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
