= Booting Kernel and Android File System from SD card =

Formatting SD Card
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): 

(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): 

(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 Disk identifier: 0x00000000

(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/ $ mkfs.ext3 -L android_fs /dev/

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 

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/ /tmp/mmc1 sudo mount /dev/ /tmp/mmc2

Load the appropriate software to the SD Card: sudo cp $YOUR_PATH/L27.10.2-P1/x-loader/MLO /tmp/mmc1  #(if you are using EMU or HS device, plese copy signed MLO instead) sudo cp $YOUR_PATH/L27.10.2-P1/u-boot/u-boot.bin /tmp/mmc1 sudo cp $YOUR_PATH/L27.10.2-P1/kernel/android-2.6.35/arch/arm/boot/uImage /tmp/mmc1 sudo cp -Rfp $YOUR_PATH/L27.10.2-P1/myfs/* /tmp/mmc2 sudo chmod -R 777 /tmp/mmc2/* sync sudo umount /tmp/mmc1 sudo umount /tmp/mmc2

=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 bootargs

L27.10.2-P1 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,1:16M consoleblank=0' setenv bootcmd 'mmcinit 0;fatload mmc 0 0x80000000 uImage; bootm 0x80000000' boot

=Known Issues= 1. Screen blacks out on start up -- set your Menu/Display/Screen timeout to 30min

2. I can't hear any audio -- we are looking into this for GB release

3. Start up takes forever -- just the initial boot-up

4. I can't play videos -- -- another thing we are targeting for GB release -- we are still working on community release of codecs needed for AV playback
