PANDABOARD DOTA

building the Kernel:-
---------------------
git clone https://android.googlesource.com/kernel/omap
cd omap
git checkout remotes/origin/android-omap-panda-3.0
make ARCH=arm CROSS_COMPILE=/home/ramchandra/ics/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- mrproper
make ARCH=arm CROSS_COMPILE=/home/ramchandra/ics/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- defconfig panda_defconfig
make uImage
replace the kernel binary image under ics/device/ti/panda from arch/arm/boot/zImage
# From: www.android.com > Partners > Getting the Source
# http://source.android.com/source/downloading.html
mkdir bin
export PATH=$PWD/bin:$PATH
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > bin/repo
chmod a+x bin/repo
# We want master
mkdir ics
cd ics
repo init -u https://android.googlesource.com/platform/manifest
repo sync
# From http://source.android.com/source/building.html
# and
# device/ti/panda/README
******replace the kernel binary image under device/ti/panda from arch/arm/boot/zImage
source build/envsetup.sh
lunch full_panda-eng
make fastboot
# Fetch the binaries from http://code.google.com/android/nexus/drivers.html#panda and extract it into ics root directory resulting into a "vendor" folder
wget --no-check-certificate https://dl.google.com/dl/android/aosp/imgtec-panda-itl41d-dfebf249.tgz
tar -zxvf imgtec-panda-itl41d-dfebf249.tgz
# accept license
make -j8
# wait a bit

Partitioning the SD-Card
--------------------------
Using fdisk /dev/sdX
make the following partitions in the sd card
sdX1 --->boot (64MB)
sdX2 --->system(around 1GB)
sdX3---->cache (64MB)
sdX4---->userdata(256MB)
sdX5---->sdcard(128MB)
sdX6---->our minimal fs (64MB)
sudo mkfs.vfat -F 32 -n "boot" /dev/sdX1
sudo mkfs.ext4 -j -L "system" /dev/sdX2
sudo mkfs.ext4 -j -L "cache" /dev/sdX3
sudo mkfs.ext4 -j -L "userdata" /dev/sdX4
sudo mkfs.ext4 -j -L "sdcard" /dev/sdX5
sudo mkfs.ext4 -j -L "amifs" /dev/sdX6
It will look like this :
Disk /dev/sdb: 3974 MB, 3974103040 bytes
128 heads, 32 sectors/track, 1895 cylinders
Units = cylinders of 4096 * 512 = 2097152 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000a10f8
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 66 135136 c W95 FAT32 (LBA)
Partition 1 does not end on cylinder boundary.
/dev/sdb2 67 322 524288 83 Linux
/dev/sdb3 323 450 262144 83 Linux
/dev/sdb4 451 706 524272 83 Linux
/dev/sdb5 739 770 65520 83 Linux
/dev/sdb6 707 738 65520 83 Linux
Partition table entries are not in disk order
--------------------------------------------------------------------------------------
# copy in the boot
mkdir mnt
sudo mount /dev/sdc1 mnt
sudo cp device/ti/panda/xloader.bin mnt/MLO
sudo cp device/ti/panda/bootloader.bin mnt/u-boot.bin
sudo umount mnt
sync
# Then plug the SD card into the Panda and USB into J18 and power on the unit
sudo ./fastboot devices
sudo fastboot oem format
sudo fastboot flash xloader device/ti/panda/xloader.bin
sudo fastboot flash bootloader device/ti/panda/bootloader.bin
sudo fastboot erase cache
sudo fastboot flash system out/target/product/panda/system.img
sudo fastboot flash userdata out/target/product/panda/userdata.img
sudo fastboot flash boot out/target/product/panda/boot.img
Now your bootable SD-Card is ready , Put your SD-Card in pandaboard :-
