How to run 0xlab android 2.1 audio player

Step 1：

reference to：http://code.google.com/p/0xdroid/wiki/Source

then repo the android2.1 source code

just "make" it

when successfully built,we want to generated new root file system, just copy the rebuild file


mad@mad-desktop:~$ mkdir fatma
mad@mad-desktop:~$ cd fatma
mad@mad-desktop:~$ cp out/target/product/beagleboard/root/* .
mad@mad-desktop:~$ cd ~/fatma/system
mad@mad-desktop:~$ cp out/target/product/beagleboard/system/* .
mad@mad-desktop:~$ cd ~/fatma


solve thing the 0xlab cant play audio,we add some script command in android script


mad@mad-desktop:~$ vim ~/fatma/system/etc/init.goldfish.sh


add command to last line


# kernel 2.6.29
alsa_amixer set 'PredriveL Mux' DACL2
alsa_amixer set 'PredriveR Mux' DACR2
# kernel 2.6.32
# alsa_amixer set 'PredriveR Mixer AudioR2' on
# alsa_amixer set 'PredriveL Mixer AudioL2' on

alsa_amixer set PreDriv 100 unmute
alsa_amixer set 'DAC2 Digital Fine' 50



mad@mad-desktop:~$ vim ~/fatma/system/etc/init.omap3.sh


add command to last line


# kernel 2.6.29
alsa_amixer set 'PredriveL Mux' DACL2
alsa_amixer set 'PredriveR Mux' DACR2
# kernel 2.6.32
# alsa_amixer set 'PredriveR Mixer AudioR2' on
# alsa_amixer set 'PredriveL Mixer AudioL2' on

alsa_amixer set PreDriv 100 unmute
alsa_amixer set 'DAC2 Digital Fine' 50


ok! now we compress the "fatma folder" to ubi fs image

we must use CD's attach tool, copy three files"mkfs.ubifs"，"ubinize"，"ubinize.cfg" to the linux OS.


mad@mad-desktop:~$ mkdir fatmaubi
mad@mad-desktop:~$ cd fatmaubi
mad@mad-desktop:~$ ls
total 78344
drwxr-xr-x 2 mad mad 4096 2010-07-29 22:01 .
drwxr-xr-x 6 mad mad 4096 2010-07-29 17:28 ..
-rw-r--r-- 1 mad mad 174424 2010-01-04 19:28 mkfs.ubifs
-rw-r--r-- 1 mad mad 79030 2010-01-04 19:28 ubinize
-rw-r--r-- 1 mad mad 124 2010-01-04 19:28 ubinize.cfg


we must change file mode to excutable


mad@mad-desktop:~$ chmod 755 mkfs.ubifs
mad@mad-desktop:~$ chmod 755 ubinize
mad@mad-desktop:~$ sudo ./mkfs.ubifs -r ~/fatma -m 2048 -e 129024 -c 812 -o ubifs.img
generate ubifs.img
mad@mad-desktop:~$ sudo ./ubinize -o ubi.img -m 2048 -p 128KiB -s 512 ubinize.cfg
generate ubi.img


download the 0xloab's devkit8k-eclair-0x4.zip and flash-uboot.bin
http://downloads.0xlab.org/release/devkit8k-eclair-0x4/devkit8k-eclair-0x4.zip
http://downloads.0xlab.org/release/devkit8k-eclair-0x4/flash-uboot.bin
unzip devkit8k-eclair-0x4.zip,and put flash-uboot.bin to folder
now we can see 5 file

0xkernel.bin
android.ubi
flash-uboot.bin
install.conf
uImage.bin

reference to http://code.google.com/p/0xdroid/wiki/UsingPreBuiltImages
copy to SD card FAT32 partition

rename ubi.img to android.ubi and cover the android.ubi on the folder
