Tools & Dependency for Building

Pre-requisite packages for build Android Filesystem (Note this is with reference to uBuntu 8.04)

If you are behind firewall, you will have to set-up firewall using the instructions in Support Tools

For higher versions of U-buntu please refer to Host PC COnfiguration

The following commands will install the correct packages to your server:

sudo apt-get install git-core flex bison gperf libesd0-dev libwxgtk2.6-dev zlib1g-dev build-essential libstdc++5 tofrodos
sudo apt-get install x-dev
sudo apt-get install libx11-dev
sudo apt-get install libncurses5-dev
sudo apt-get install sun-java6-jdk

64-bit environment users must install g++.multilib:

sudo apt-get install g++-multilib

“Intrepid (8.10) users may need a newer version of libreadline:

sudo apt-get install lib32readline5-dev”

Booting Kernel and Android from SD

You will need to format your SD for the Linux file system. Connect your SD memory card reader with memory card inserted to a USB port on your Linux Ubuntu PC. You must login as Super User.

$ su
$ fdisk -l

Match the device to the size of your memory card. Look for the /dev/*** device which matches the memory card in the card reader. Use the matching device’s letter prefix in the next command. For example if the device for memory card reader card example was: /dev/sdb1, then use only /dev/sdb in the fdisk command.

Take note of the size in bytes of your SD Card. You will need this to calculate the number of cylinders in a future step.

$ fdisk /dev/sdb  (replace sdb with the letter prefix for your device)

(Delete all partitions on the card if they exist)
Command (m for help): d
Partition number (1-4): 1
Command (m for help): d
Selected partition 2

Command (m for help): x

(Change the number of heads, sectors and cylinders on the device)
Expert command (m for help): h
Number of heads (1-256, default 255): 255
Expert command (m for help): s
Number of sectors (1-63, default 63): 63
Expert command (m for help): c
Number of cylinders (1-1048576, default 248): <You must calculate the number of cylinders for your SD card.  To do this, use the following formula:  

new_cylinders = (Size in bytes from your fdisk –l command)/8225280
Drop any fractional values and enter the whole number in this command.
Use this number all the steps that refer to the number of cylinders>

(Now return to the main menu)
Expert command (m for help): r

(Create the first partition)
Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-248, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-248, default 248): +64M

If you plan to use this SD card partition for storing media your can use +1024M assuming a 2+ GB SD card.

(Create the second partition)
Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 2
First cylinder (10-248, default 10): 10
Last cylinder or +size or +sizeM or +sizeK (124-248, default 248): <use the cylinder value you calculated earlier>  

(Change the first partition to at FAT32 partition)
Command (m for help): t
Partition number (1-4): 1
Hex code (type L to list codes): c
Changed system type of partition 1 to c (W95 FAT32 (LBA))

(Toggle the bootable flag for partition 1)
Command (m for help): a
Partition number (1-4): 1

(Print the partition table to confirm your settings)
Command (m for help): p

(Sample Output – your output may differ depending on your SD card’s size and brand)
Disk /dev/sdb: 2041 MB, 2041577472 bytes
255 heads, 63 sectors/track, 248 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

(Write your changes to the SD Card)	
Command (m for help): w

(You will see the following output)
The partition table has been altered!

Calling ioctl() to re-read partition table.


WARNING: If you have created or modified any DOS 6.x partitions, please see the fdisk manual page for additional information.
Syncing disks.

Format your partitions typing the following commands (logged as root@ubuntu-box):
$ mkfs.vfat -F 32 -n boot /dev/<your device’s first partition’s name – see the print output from the previous step> 
$ mkfs.ext3 -L android_fs /dev/<your device’s second partition’s name – see the print output from the previous step> 

There is a shell script that all calculations above automatically; to get it do:
$ wget http://cgit.openembedded.org/cgit.cgi/openembedded/plain/contrib/angstrom/omap3-mkcard.sh

Add execution permission:
$ chmod +x omap3-mkcard.sh

And you are ready to use it by just typing:
$sudo ./omap3-mkcard.sh <your_device (e.g. /dev/sdb)>

Copying Binaries onto SD Card

Now type the following to mount your SD Card on your Linux box:

mkdir /tmp/mmc1
mkdir /tmp/mmc2
sudo mount /dev/<your device’s first partition’s name> /tmp/mmc1
sudo mount /dev/<your device’s second partition’s name> /tmp/mmc2

Load the appropriate software to the SD Card:

sudo cp $YOUR_PATH/L27.12.1-P2/x-loader/MLO /tmp/mmc1   #(if you are using EMU or HS device, plese copy signed MLO instead)
sudo cp $YOUR_PATH/L27.12.1-P2/u-boot/u-boot.bin /tmp/mmc1
sudo cp $YOUR_PATH/L27.12.1-P2/kernel/android-2.6.35/arch/arm/boot/uImage /tmp/mmc1
sudo cp -Rfp $YOUR_PATH/L27.12.1-P2/myfs/* /tmp/mmc2
sudo chmod -R 777 /tmp/mmc2/*
sync
sudo umount /tmp/mmc1
sudo umount /tmp/mmc2

SD Booting

Insert your SD card (with u-boot, x-loader and uImage loaded in FAT partition and ) into PandaBoard SD/MMC card slot, then plug the PandaBoard mini USB port to your PC and open a serial terminal (baudrate:115200, no parity, 8 bits). Power your board up and in your terminal window you should be able to see the ‘New’ u-boot prompt:

“PANDA #”

In your serial terminal define the bootargs and boot as mentioned in the bootarg section.</br>

Right after this your PandaBoard should start booting using the kernel image and loading the Android filesystem from your SD

Bootargs

Note that parameter mem=456M@0x80000000 mem=512M@0xA0000000 should be used in the bootargs

L27.12.1-P2 Bootargs for SD card boot

setenv bootargs 'console=ttyO2,115200n8 androidboot.console=ttyO2 mem=456M@0x80000000 mem=512M@0xA0000000 root=/dev/mmcblk0p2 rw rootdelay=2 init=/init vram="32M" omapfb.vram=0:16M omapdss.def_disp=hdmi consoleblank=0' 
setenv bootcmd 'mmcinit 0;fatload mmc 0 0x80000000 uImage; bootm 0x80000000'
boot

NOTE: some people have reported problems with copy-n-paste with the single line bootargs listed above. use this set of bootargs for paste functions:

setenv console console=ttyO2,115200n8 androidboot.console=ttyO2
setenv memory mem=456M@0x80000000 mem=512M@0xA0000000
setenv rootfs root=/dev/mmcblk0p2 rw rootdelay=2 init=/init
setenv vmem  vram="32M" omapfb.vram=0:16M
setenv display omapdss.def_disp=hdmi consoleblank=0
setenv bootargs ${console} ${memory} ${rootfs} ${vmem} ${display}
printenv bootargs
setenv bootcmd 'mmcinit 0;fatload mmc 0 0x80000000 uImage; bootm 0x80000000'
boot

Preparing Android using Fastboot Bootup

Booting into fastboot

Hold down the the input button (button located furthest away from SD card) during bootup. This will bring pandaboard up into fastboot. Below is what you should see:

Creating SD GPT Partitions

on Host
cd $MYDROID/out/target/product/pandaboard/
sudo ./../../../host/linux-x86/bin/fastboot oem format
new partition table:
     256     128K xloader
     512     256K bootloader
    2048       8M recovery
   18432       8M boot

Flashing bootloader, xloader and boot image.

This step is only done once. This simply creates the GPT table required for booting. If you have a new SD card you should preform this step. If you have already preform this step you can easily just flash binaries to the SD card.

cd $MYDROID/out/target/product/pandaboard/
sudo ./../../../host/linux-x86/bin/fastboot flash bootloader boot/u-boot.bin
sudo ./../../../host/linux-x86/bin/fastboot flash xloader boot/MLO
sudo ./../../../host/linux-x86/bin/fastboot flash boot boot.img

Power down and restart --hold down button during boot and re-enter fastboot

Flashing complete environment

This step will flash the entire android system to the SD card.

cd $MYDROID/out/target/product/pandaboard/
sudo ./fastboot.sh

See Android_eMMC_Booting for more information regarding fastboot on Android.
