Does Android support composite video??

Fri Oct 26, 2012 5:16 pm

I download an Android gingerbread port "Gingerbread+EthernetManager.img" a while ago I assume it's from http://androidpi.wikia.com/wiki/Android_Pi_Wiki it has the same filename this image.

Anyway I booted the image, I got a load of text flying by and then the screen goes blank.
5 minutes later nothing happens the screen still remains blank.
Then I switched back to console mode (Ctrl+Alt+F1) and performed "ps" from what I can see all the processes required for Android are up and running but when I go back to the graphics screen Ctrl+Alt+F7 is still blank.

Is this because the Android port only works with HDMI??

If that's the case would the official Broadcom ICS release also be restricted to HDMI as well??

I remember that there were problems with composite, not sure if there was a fix though... You can try reading some posts around here in the Android section, you may find the solution.

I have booted CyanogenMOD 7.2 (with Ethernet Menu) using the composite video out on pi. The boot process hangs on other errors I'm working on. To reproduce do:

1. Download the image.
http://rosefire.us/%7Erazdroid/aaa801/G ... Manager.7z
2. Build CM7 as per instructions:
http://androidpi.wikia.com/wiki/CM7_Com ... leComments
3. Your build will be in out/target/product/rpi/root. The 'system' folder needs to be copied into 'root'. The files that are in the root folder should be copied to the root of your SD filesystem partition.

I fixed the write error by modifying the mount options to rw for / in the init.rc file. I'm not sure how to go about using logcat on pi. Can you advise? I have it connected to my laptop but it is not recognised like a mobile.

OK I followed the instructions below but I cannot connect to the adb service on the pi

Append /init.rc
service startEth0 /system/bin/startEth0.sh
chmod +x /system/bin/startEth0.sh

Create the file /system/bin/startEth0.sh.

#!/system/bin/sh
export ADBHOST=192.168.1.2
setprop service.adb.tcp.port 5555
ifconfig eth0 192.168.1.2 netmask 255.255.255.0.0
setprop net.dns1 8.8.8.8
adb kill-server
adb start-server


Then from my laptop with address 192.168.1.1

adb connect 192.168.1.2:5555

No joy...

adb should be auto started on boot, with the next dhcp ip, run a portscan on your subnet for 5555 and you should find the pi

Thanks for the info. I was hoping to configure it with a static ip address as I don't have a dhcp server running on the network. Can you provide me any info about this? I got my hands on an hmdi monitor and I can see android has booted successfully but no joy with the composite out.

I might try and debug it later, i have my suspecions that its people just not configuring it properly
