Hi, also on my N800 m5-rc15 give me some problem.
The principal problem is for low memory, because this version uses around
50MB of memory and maemo up and running uses 80MB. To solve this problem
I've reflashed N800 with the option "--*set-rd-flags*=no-lifeguard-reset" so
I can stop X and other essential service without reboot the device. I launch
the following free-memory.sh script:
#!/bin/sh -x
/etc/init.d/zzinitdone stop
/etc/init.d/alarmd stop
/etc/init.d/mediaplayer-daemon stop
/etc/init.d/bme-dbus-proxy stop
/etc/init.d/af-base-apps stop
/etc/init.d/btcond stop
/etc/init.d/dbus stop
/etc/init.d/gpsdriver stop
/etc/init.d/hildon-desktop stop
/etc/init.d/hulda stop
/etc/init.d/libgpsbt stop
/etc/init.d/obexsrv stop
/etc/init.d/af-startup stop
/etc/init.d/af-services stop
/etc/init.d/x-server stop
/etc/init.d/maemo-launcher stop
/etc/init.d/osso-systemui stop
/etc/init.d/bluez-utils stop
/etc/init.d/multimediad stop
/etc/init.d/mce stop
/etc/init.d/product-code stop
/etc/init.d/hildon-update-notifier stop
/etc/init.d/metalayer-crawler0 stop
/etc/init.d/esd stop
After this script Maemo uses only around 60MB of memory and after than I run
Android with more success. Moreover, actually I launch Android via init with
the following script start_android_init.sh:
#!/bin/sh -x
echo "Starting Android..."
rm -rf /media/mmc1/tmp/*
echo z > /proc/sysrq-trigger
umount /proc
umount /sys
chmod -R 777 /media/mmc1
umask 000
chroot /media/mmc1 /init.sh
At last, I've compiled in the kernel also the module low-memory-killer
present on android linux kernel. I think isn't fundamental but if you want
insert this driver apply the patch attached to the mail.
After that, if your sound subsystem works tell me what you have done...:D
Best Regards,
Andrea Bernardi
P.S.: the patch for the double buffer showed in the previuos mail isn't
perfect, you see only interleaved frame on your screen...
