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 -lMatch 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):(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.

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/Load the appropriate software to the SD Card:/tmp/mmc1 sudo mount /dev/ /tmp/mmc2
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.
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 bootargsL27.12.1-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' bootNOTE: 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

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:Texas Instruments X-Loader 1.41 (May 17 2011 - 10:31:50)

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.imgPower 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

PandaBoard Cortex-A9
Like the related open-platform BeagleBoard.org and newer HawkBoard.org projects, PandaBoard.org developed and supports a board incorporating a Texas Instruments SoC that targets hobbyists, as well as professional developers wanting to prototype new embedded designs. (The HawkBoard is built around the ARM9-based OMAP-L138.)
PandaBoard
(Click to enlarge)
Like the BeagleBoard, which recently moved up from its OMAP3530 foundation to a 720p-ready DM3730 SoC in its BeagleBoard-xM version, the PandaBoard is distributed by Digi-Key. Whereas both BeagleBoard versions are based on ARM Cortex-A8 SoCs and targeted at the general embedded device market, the 4.0 x 4.5-inch PandaBoard moves up to the Cortex-A9-based 1GHz OMAP4430 SoC and is more specifically aimed at smartphones and other mobile devices. The board can record and play back video with 1080p quality at 30 frames per second, says PandaBoard.org .
Texas Instruments began sampling the OMAP
4430
and OMAP4440 in February. At the same time TI introduced a Linux- and
Android-compatible "Blaze" hardware/software development platform in
smartphone format. The Blaze (pictured) sports a pico projector, dual
3.7-inch displays, three cameras, an HDMI output, a compass, plus a
barometer and other sensors. The OMAP4 family was announced at the Mobile World Congress (MWC) in Feb. 2008, as we reported at the time. These 45nm SoCs (system on chips) are built around ARM's Cortex-A9 processor, which implements the same ARMv7 used on the Cortex-A8 and adds a MPCore interconnect layer for multiple processor support. While as many as four cores are possible (see block diagram, here), the OMAP4 chips use two, as depicted below.

The PandaBoard also has a 10/100 Ethernet port, dual USB 2.0 Host ports, and a USB 2.0 OTG port, says the project. An RS-232 port, camera connector, JTAG port, and stereo audio I/O are also said to be available, along with a "generic expansion connector" that supports interfaces like SD/MMC, USB, GPMC, DSS, ETM, McSPI, I2C, and UARTs. The PandaBoard measures 4.5 x 4.0 inches (114.3 x 101.6mm), up from 3.25 × 3.25 inches for the BeagleBoard-xM. Equipped with a five Volt power supply, the board features power and reset buttons as well as status LEDs, says the project.
Software
The PandaBoard is currently optimized to run several open source Linux operating systems. These include Ubuntu 10.10 and beyond, as well as a minimal Angstrom Linux distribution. There is also an Android port called Pandroid.
In addition, the platform is said to be generally compatible with Linux distributions such as MeeGo and Chrome OS.
Projects listed at the PandaBoard.org community site include RISC OS on OMAP4, XBMC, Wireless sniffer, Gentoo Linux, MeeGo, GeeXboX, OpenBricks, Pandroid, and Ubuntu on PandaBoard.
Testimonials
Stated Jon Melamut, VP of sales and product management, OEM services for Canonical -- in the first example we can recall of Canonical saying Ubuntu will be heading for tablets -- "We expect PandaBoard to be adopted across the industry as the platform of choice for developers and also to increase the impact in accelerating the usage of Ubuntu in key target markets like netbooks, tablets and new in-home products."
Stated Ben Cade, executive officer, Linaro, "PandaBoard combines the performance of a PC in the power footprint of mobile at an affordable cost; it is a very exciting option for software developers. Linaro is investing in open source tools and software to ensure that the advanced features of the dual core Cortex-A9 used on the PandaBoard can be easily used by software developers and distributions around the world."
Stated Jim Zemlin, executive director, the Linux Foundation, "We're pleased to see more and more Linux-based projects and products spring up in the embedded space. PandaBoard looks to be a great addition to the Linux developer community and will give developers access to TI's OMAP platform in a low cost way."
