onda-dual-vi30w's Introduction

SD卡运行android

onda vi30w 双核板的flash坏了，只能把android放到SD卡去运行，简单修改init.rc和vold.fstab即可。

文件说明

vi30w-dual-v2-155-boot.img是固件v155的update里的boot.img

解压内核与ramdisk文件系统

sh unpack-uImage.sh vi30w-dual-v2-155-boot.img

修改initramfs/init.rc

修改文件系统挂着，挂载sd卡

on fs
	ubiattach mtd@system
	mount ubifs ubi0_0 /system
	ubiattach mtd@userdata
	mount ubifs ubi1_0 /data nosuid nodev
	mount yaffs2 mtd@cache /cache nosuid nodev

改成

on fs
	mount ext3 /dev/block/cardblksd2 /system 
	chmod -R a+rw /system
	mount ext3 /dev/block/cardblksd3 /data 
	mount tmpfs tmpfs /cache

挂载SD卡到/mnt/sdcard

修改/system/etc/vold.fstab

dev_mount sdcard /mnt/sdcard 4 /devices/platform/AMLOGIC_CARD/card_host/memorycard0 /devices/platform/aml_sd_mmc.0

删除flash的挂载

支持adb shell

在/system/bin目录创建sh软链接到/system/xbin/busybox

cp system/xbin/busybox system/bin
cd system/bin
ln -s busybox sh

制作aml_autoscript

mkimage在linux目录的arch/arm/boo/mkimage

sh mkscript.sh linux.auto.txt
sh mkscript.sh android.auto.txt
