OMAP5 SD Card Boot Information

=SD Card Boot Instructions and Information for OMAP5=

SD Card boot is not official supported for the OMAP5 release but here are the steps required to use an SD card with OMAP5. This will require pulling and building uboot which steps are given, for each specific release the commit ID is supplied. This step will prepare a directory, called myfs, containing all necessary Android files that you must include within your SD card.

U-Boot Steps
U-Boot Sources cd ${YOUR_PATH} git clone git://git.omapzoom.org/repo/u-boot.git u-boot cd u-boot git checkout d8024a73d779672f6a7bef5aa498d85dcbf0c1ab (for release 5AI.1.9 & 5AI.1.10)

Building U-BOOT
cd ${YOUR_PATH}/u-boot git clean -fdx make CROSS_COMPILE=" arm-none-linux-gnueabi-" clean make CROSS_COMPILE=" arm-none-linux-gnueabi-" omap5_evm5430_android_config make CROSS_COMPILE=" arm-none-linux-gnueabi-" all

Generating boot.scr to boot from SD
NOTE: This is done automatically, and is based on the information in "boot.scr.omap.txt". This information is provided for information purposes only.

cd ${YOUR_PATH}/u-boot echo "i2c mw 0x48 0xd9 0x15" > boot.cmd echo "i2c mw 0x48 0xd4 0x05" >> boot.cmd echo "mmc part" >> boot.cmd echo "fatload mmc 0:1 0x80300000 uImage" >> boot.cmd echo "bootm 0x80300000" >> boot.cmd mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'OMAP5 Integration' -d boot.cmd boot.scr

Create the filesystem
cd $YOUR_PATH mkdir myfs cd myfs cp -Rfp $MYDROID/out/target/product/$BOARD_TYPE/root/*. cp -Rfp $MYDROID/out/target/product/$BOARD_TYPE/system/. cp -Rfp $MYDROID/out/target/product/$BOARD_TYPE/data/.

Create the boot partition
cd $YOUR_PATH mkdir boot cd boot cp ${YOUR_PATH}/kernel/android-3.1/arch/arm/boot/uImage. cp ${YOUR_PATH}/u-boot/MLO omap5evm_GP_ES1.0_MLO cp ${YOUR_PATH}/u-boot/u-boot.img. cp ${YOUR_PATH}/u-boot/boot.scr. For HD device (high security device) include: cp ${YOUR_PATH}/omap-mshield-lite/MLO omap5evm_HS_ES1.0_MLO

Formatting SD Card
You will need to format your SD for the Linux file system. Connect your micro SD memory card reader with memory card inserted to a USB port on your Linux Ubuntu PC.

There is a shell script that

performs all of the formatting required. Download it with:

$ 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 

Once it has finished, remove and reinsert the micro SD card. If you are logged in graphically, "/media/boot" and "/media/Angstrom" will be automatically mounted.

Otherwise you will need to mount them

manually.

Installing the required files to micro SD
Assuming your micro SD card is mounted on "/media/boot" and "/media/Angstrom", use the following commands to populate the card:

sudo cp -a ${YOUR_PATH}/boot/* /media/boot/ sudo cp -a ${YOUR_PATH}/myfs/* /media/Angstrom/ sudo sync sudo eject /media/boot
