Dear All:

right now, I have i.mx27 ADS board with 7" LCM and 7" touch panel. So I spend some time to work on the net to found out what should I do to make android running on i.MX27. after some works, I can make android m3 image running on i.mx27. the following is what I used: 1. Freescale i.MX27 ADS board with reboot 200749, bsp 20071219. 2. kernel version : 2.6.22-6 3. arm-linux-gcc : 4.1.2 4. android kernel source 2.6.23-m3 5. android on zaursu image. 6. put android image on NFS, and make i.mx27 can using them via NFS.

after comparing android's kernel source and found out what had to add into i.mx27 2.6.22-6 kernel source. I have a very early workable kernel source.

after some testing, I found a way to loading android image and make the android live on i.mx27. here is my running script.

######################################### below is the one which run under i.mx27 linux prompt. #########################################

#!/bin/sh

/system/bin/app_process -Xzygote /system/bin --zygote& sleep 10

echo "" echo "==================" echo " Booting Android 3" echo "==================" echo "" runtime

After about 3 mins, the android shows on i.mx27.

But I have some problems. Could you help me or give me some hits? 1. How to make touch panel work under android? 2. How to make android network setting to go outside world?

Thank you very much.

Best Regards,
