Get module symbol information

Check Build/BeagleBoard/DEBUG_ARMGCC/FV/FVMAIN_COMPACT.Fv.map
Get .textbaseaddress and .databaseaddress

Load symbol information

-s for waiting for gdb connection
-S for stopping execution when qEmu starts up

Connecting qEmu using GDB

Build EDK2 BeagleBoardPkg on Mac OS X

Install XCode


Install MacPorts


Install ARM toolchain 

sudo port install arm-none-eabi-gcc 

Within Darwin section in  BeagleBoardPkg/build.sh

Change XCODE32 to ARMGCC

Build

./build.sh

Linaro image tools for Mac OS X

Not available yet
https://bugs.launchpad.net/linaro-image-tools
My workaround is making image on the Ubuntu and load it to Mac
Looking forward tools for Mac OS X
Temporarily switch back to Ubuntu

UEFI Boot Linaro images on qEmu based BeagleBoard

Build EDK2 BeagleBoardPkg


Boot Linaro-m alip (Kubuntu 10.10)

Install needed packages
KPH$ sudo apt-get install parted dosfstools uboot-mkimage python-argparse python-dbus python-debian python-parted qemu-arm-static btrfs-tools command-not-found

Create and change to working directory
KPH$ cd $(WORKROOT)
KPH$ mkdir -p linaro-m/alip && cd linaro-m/alip

Get image and hardware packs
KPH$ wget http://releases.linaro.org/platform/linaro-m/alip/final/linaro-m-alip-tar-20101109-0.tar.gz http://releases.linaro.org/platform/linaro-m/hwpacks/final/hwpack_linaro-omap3_20101109-1_armel_supported.tar.gz

Install Linaro image tools
KPH$ sudo add-apt-repository ppa:linaro-maintainers/tools
KPHsudo apt-get update
KPHsudo apt-get install linaro-image-tools

Create u-boot and Linux Linaro image
KPHsudo linaro-media-create --image_file alip.img --dev beagle --binary linaro-m-alip-tar-20101109-0.tar.gz --hwpack hwpack_linaro-omap3_20101109-1_armel_supported.tar.gz
KPH$ sudo chmod a+rw alip.img

Replace u-boot.bin with UEFI
KPHmkdir /tmp/alip_boot/
KPHsudo mount -o loop,offset=$[63*512] $(WORKROOT)/linaro-m/alip/alip.img /tmp/alip_boot
KPH$ sudo cp $(EDK2ROOT)/edk2/Build/BeagleBoard/RELEASE_ARMGCC/FV/BEAGLEBOARD_EFI.fd /tmp/alip_boot/u-boot.bin
KPH$ sudo umount /tmp/alip_boot

ARM UEFI only supports zImage currently, so add zImage to the sdcard
KPH$ tar xzf hwpack_linaro-omap3_20101109-1_armel_supported.tar.gz
KPH$ cd pkgs/
KPH$ dpkg -x linux-image-2.6.35-1008-linaro-omap_2.6.35-1008.15_armel.deb .
KPH$ sudo mount -o loop,offset=$[63*512] $(WORKROOT)/linaro-m/alip/alip.img /tmp/alip_boot
KPH$ sudo cp boot/vmlinuz-2.6.35-1008-linaro-omap /tmp/alip_boot/zImage

Install ARM qEmu
KPH$ sudo add-apt-repository ppa:linaro-maintainers/tools
KPH$ sudo apt-get update
KPH$ sudo apt-get install qemu-user-static qemu-system

Test UEFI on qEmu
KPH$ sudo qemu-system-arm -M beagle -serial stdio -sd alip.img

Takes a while for the GUI desktop on qEmu



























With similar steps you could try another images you like. 
Enjoy. :)
