Making the rootfs.tar.bz2 is very very slow in Android system build

Hi Eric,

Could you follow the steps in the latest guide at http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_DeveloperGuide#To_build_Android_filesystem

The Android filesystem build may take 1 hour in a machine with 4GB RAM.

Regards,

Arun

hi Arun Joseph,

      Thank you for your reply.

      Now I can build it very fast. The TI-Android-GingerBread-2.3-DevKit-1.0 DeveloperGuide is missing the line for mkdir of android_rootfs...so on.

Thanks

Eric

Hi,

       I had another problem:

       I try to use mkmmc-android.sh to put file into SD Card.

sudo ./mkmmc-android /dev/mmcblk0 MLO u-boot.bin uImage boot.scr rootfs.tar.bz2

     I get error for this:

     " mkmmc-android: command no find"

     I don't know why it is happened. Is it any package missing for running mkmmc-android.sh?

mkmmc-android.sh is available in the prebuilt images package.

Hi Vishveshwar,

               I had already put all the file into image_folder including mkmmc-android.sh.

The following is the terminal list:

///////

eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ dir
boot.scr  mkmmc-android.sh  MLO  rootfs.tar.bz2  u-boot.bin  uImage
eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ mkmmc-android /dev/mmccblk0 boot.scr  MLO  rootfs.tar.bz2  u-boot.bin  uImage
mkmmc-android: command not found

/////

Eric,

It looks like you are missing the leading './' so the system is unable to locate this script.Also the order of the files is important

Please run it as follows: (See http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_UserGuide#Procedure_to_populate_MMC.2FSD_Card)

eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ sudo ./mkmmc-android /dev/mmcblk0 MLO u-boot.bin uImage boot.scr  rootfs.tar.bz2

Since you are not root you need to run the command with 'sudo' to be able to write on sdcard

Hi, Vishveshwar,

I had tried your suggestion. The result is same "command no find".

Please see below:

///// i try

eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ sudo ./mkmmc-android /dev/mmcblk0 MLO u-boot.bin uImage boot.scr rootfs.tar.bz2
[sudo] password for eric2011:
sudo: ./mkmmc-android: command not found
eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ cd ..

//// i try
eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources$ sudo ./mkmmc-android /dev/mmcblk0 MLO u-boot.bin uImage boot.scr rootfs.tar.bz2
sudo: ./mkmmc-android: command not found

/// i try
eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources$ ./mkmmc-android /dev/mmcblk0 MLO u-boot.bin uImage boot.scr rootfs.tar.bz2
bash: ./mkmmc-android: No such file or directory

Is it the problem for bash?

I am sorry. There was a typo in the above command.

You should use ./mkmmc-android.sh not ./mkmmc-android

Hi, Vishveshwar:

The result is same

eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ sudo ./mkmmc-android.sh /dev/mmcblk0 MLO u-boot.bin uImage boot.scr rootfs.tar.bz2
sudo: unable to execute ./mkmmc-android.sh: No such file or directory
eric2011@eric2011-laptop:~/rowboat-android/TI_Android_GingerBread_2_3_Sources/image_folder$ ./mkmmc-android.sh /dev/mmcblk0 MLO u-boot.bin uImage boot.scr rootfs.tar.bz2
bash: ./mkmmc-android.sh: /bin/bash^M: bad interpreter: No such file or directory

Hi Eric,

I think the mkmmc-android.sh is in DOS format. Please convert this file to UNIX format and try again.

command:

dos2unix mkmmc_android.sh

chmod 777 mkmmc_android.sh

Thanks and Regards,

Hi,

  The mkmmc_android.sh is working when I replace another file which download from web.

  I had an question that how to find the MMC card device name .I had gotten the name of device from Disk Utility and put it into device name /dev/.... But it is not working.

Hi Eric,

You can use sudo  fdisk -l command to see the SD card mount point.

Thanks and Regards,
