The Beagle Board is a low cost highly capable single board computer. The Beagle Board is based on an OMAP3530 SoC featuring an ARM® CortexTM-A8 processor. Please go here, to get information on how to buy a Beagle Board. Don't forget to also order a serial cable and power supply.
The BeagleBoardPkg package reuses components from ArmPkg and Omap35xxPkg.

BeagleBoard Support and Status

  • Tested revision 12923 (Tue Jan 10 2012)
  • NAND, SD Card, USB EHCI controller, Display controller EFI Drivers are fully functional.
  • Boot Linux zImage with ATAG or Device Tree blob (FDT)

How to build UEFI for the BeagleBoard

1. Get the requirements

  • A Universally Unique Id (UUID) header. Needed to build the EDK2 BaseTools. On Ubuntu: sudo apt-get install uuid-dev
2. Download the sources
svn co edk2 --username guest
cd $(WORKROOT)/edk2
svn co FatPkg --username guest
patch -p1 < ArmPlatformPkg/Documentation/patches/BaseTools-Pending-Patches.patch
cd BeagleBoardPkg/

3. Get the toolchain: See ArmPkg-Toolchain

4. Apply the ARM pending patches required to build the firmware

cd $(WORKROOT)/edk2
patch -p0 < ArmPlatformPkg/Documentation/patches/BaseTools-Pending-Patches.patch

5. Build the Release build of UEFI firmware:

cd BeagleBoardPkg/
  • To Build the Debug version of UEFI

Using UEFI to boot Linux

1. Installing Linaro image Creator:

  • Getting from Linaro website:
tar xzf linaro-image-tools-0.4.8.tar.gz
cd $(WORKROOT)/linaro-image-tools-0.4.8/
sudo apt-get install parted dosfstools uboot-mkimage python-argparse python-dbus python-debian python-parted qemu-arm-static btrfs-tools command-not-found
Add linaro-media-create path to the PATH environment variable
  • Getting from the Ubuntu package:
sudo add-apt-repository ppa:linaro-maintainers/tools
sudo apt-get update
sudo apt-get install linaro-image-tools

2. Creating the u-boot + Linux Linaro image:

mkdir $(WORKROOT)/beagle_image && cd $(WORKROOT)/beagle_image
sudo linaro-media-create --image_file beagle_sd.img --dev beagle --binary linaro-m-headless-tar-20101101-0.tar.gz --hwpack hwpack_linaro-omap3_20101109-1_armel_supported.tar.gz
sudo chmod a+rw beagle_sd.img

3. Replacing u-boot by UEFI

mkdir /tmp/beagle_boot
sudo mount -o loop,offset=$[63*512] $(WORKROOT)/beagle_image/beagle_sd.img /tmp/beagle_boot
sudo cp $(WORKROOT)/edk2/Build/BeagleBoard/RELEASE_ARMGCC/FV/BEAGLEBOARD_EFI.fd /tmp/beagle_boot/u-boot.bin
sudo umount /tmp/beagle_boot

4. ARM UEFI currently only support zImage. Add the zImage to the sdcard:

tar xzf hwpack_linaro-omap3_20101109-1_armel_supported.tar.gz
cd pkgs/
dpkg -x linux-image-2.6.35-1008-linaro-omap_2.6.35-1008.15_armel.deb .
sudo mount -o loop,offset=$[63*512] $(WORKROOT)/beagle_image/beagle_sd.img /tmp/beagle_boot
sudo cp boot/vmlinuz-2.6.35-1008-linaro-omap /tmp/beagle_boot/zImage

5. Replace the Linux command line

  • Get the command line from uboot ('boot.txt' from the boot partition):
console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw earlyprintk fixrtc nocompcache vram=12M omapfb.mode=dvi:1280x720MR-16@60
  • Start the UEFI on the BeagleBoard
  • Go into the 'Boot Menu'
  • Update the existing entry
The default boot selection will start in   8 seconds

The EBL (EDK Boot Loader) is a small simple command line environment that is much simpler that the EFI shell. It is also possible to launch the EFI shell from the EBL command prompt. The EBL source code is located in the edk2 EmbeddedPkg.
Please see the EDK Boot Loader (EBL) WiKi for more information.

Testing UEFI on qEmu

sudo add-apt-repository ppa:linaro-maintainers/tools
sudo apt-get update
sudo apt-get install qemu-user-static qemu-system
  • Using the previous image:
qemu-system-arm -M beagle -serial stdio -sd beagle_sd.img
  • Booting UEFI from NOR Flash: Rebuild the UEFI firmware WITH the OMAP353x header:
cd $(WORKROOT)/edk2/BeagleBoardPkg/
qemu-system-arm -M beagle -serial stdio -sd beagle_sd.img -mtdblock $(WORKROOT)/edk2/Build/BeagleBoard/RELEASE_ARMGCC/FV/BeagleBoard_EFI_flashboot.fd 
  • If UEFI fails to find the Linux kernel then you should expect to see this error message:
ERROR : Did not find linux kernel.

Two reasons could be the source of the error. Either there is no zImage on the SD card (the default location of the kernel for this version of UEFI) or the Device Path of the SD card has changed.

To check if the zImage is on the SD card, start EBL and browse the SD card file system to ensure a 'zImage' file exists on the root of your boot partition:

Booting EDK2 in the Beagle Board DRAM using U-Boot

1. Build the BeagleBoard EDK2 as defined in section 'How to build UEFI for the BeagleBoard'.

2. Copy the BeagleBoard UEFI firmware (BEAGLEBOARD_EFI.fd) on your boot partition (the FAT partition) of your SD card.

3. Start U-Boot on the BeagleBoard

4. Load and Start the UEFI Firmware
