=== SmdkBoard OVERVIEW ===
The SMDK project aims to support firmware for Exynos 4210 Soc using the edk2
code base.
=== STATUS ===
Current status: Alpha
Current capabilities:
* Uefi Boot from SDMMC card
=== FUTURE PLANS ===
* SUpport for USB
- KeyBoard, Mouse and MassStorage
=== BUILDING SMDK Board ===
Pre-requisites:
* Build environment capable of build the edk2 MdeModulePkg.
* A properly configured ASL compiler:
- Intel ASL compiler: Available from http://www.acpica.org
- Microsoft ASL compiler: Available from http://www.acpi.info
Building the iRam_Bl:
The iRam_Bl is the 1st stage bootloader which is executed by the IROM code.
This code is reused from the u-boot project. this image has to be a plane binary image
which will not have any header format. After generating the binary image the checksum is generated
and stored in the same file at a particular offset. that is done by the executable generated with
the iRam_Bl source files.
To generate the iRAM_Bl image
* Download the u-boot source from git://git.denx.de/u-boot.git by running below command
git clone git://git.denx.de/u-boot.git
* Run following commands
- export ARCH=arm
- export CROSS_COMPILE=/usr/local/arm/gcc-linaro-4.5-2011.03-0/bin/arm-linux-gnueabi- or respective toolchain path
- make smdkv310_config
- make mmc_spl
* the binary "u-boot-mmc-spl.bin" will be generated in the spl directory.
* copy the generated u-boot-mmc-spl.bin to the Uefi Workspace Build/SmdkBoard-Exynos/RELEASE_ARMGCC/FV/
Build the SdmkBoardPkg by running from the Workspace
build -p SamsungPlatformPkg/SmdkBoardPkg/SmdkBoardPkg-Exynos.dsc -a ARM -t ARMGCC -b RELEASE for release version
Following the edk2 build process, you will find the SMDK binaries
under the $WORKSPACE/Build/*/*/FV directory. You can find the below
mentioned binary image.
* SMDKBOARD_EFI.FD
* u-boot-mmc-spl.bin
=== RUNNING SmdkBoardPkg on the SMDK v310 board ===
* need to be in Linux Environment to do the below procedure
* After inserting the SD card. unmount the card by using the command umount /media/XXXXX.
* copy the u-boot-mmc-spl.bin to the SD/MMC card by using the comand
sudo dd if=Build/SmdkBoard-Exynos/RELEASE_ARMGCC/FV/u-boot-mmc-spl.bin of=/dev/sdc bs=512 seek=1
* Copy the Uefi Image to SD/MMC with below command from the Workspace.
sudo dd if=Build/SmdkBoard-Exynos/RELEASE_ARMGCC/FV/SMDKBOARD_EFI.fd of=/dev/sdc bs=512 seek=65
* Now the booting device is ready to be used.
* Insert the SDMMC card in the v310 board reader slot MMC Ch2.
* Connect the Uart cable from the v310 device to the PC terminal.
* POwer ON the Device.
* The boot message should be visible on the termial.
* use option 1 to enter the Embedded Boot loader.
