Prior to use ICE debugger with Versatile Express, you will need to update the version of the ICE's firmware. If you have not installed RealView 4.0 SP3, do it. Open "RealView ICE Update" and "Install Firmware Update ...". Install "[ARM_INSTALL_PATH]\RVI\Firmware\3.4\11\ARM-RVI-3.4.0-25-base.rvi" and "[ARM_INSTALL_PATH]\RVI\Firmware\3.4\22\ARM-RVI-3.4.59-59-patch.rvi".
1. Get EDK2 from Tianocore Subversion repository
svn co https://svn.code.sf.net/p/edk2/code/trunk/edk2 edk2 --username guest
2. Set up the environment. And build the EDK2’s tools
. edksetup.sh make -C BaseTools
3. Ensure the GCC toolchain is in your PATH environment variable or defined by the GCC47_ARM_PREFIX environment variable. Example:
export GCC47_ARM_PREFIX=/opt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.08_linux/bin/arm-linux-gnueabihf-
4. Build the ARM Versatile Express UEFI Firmware
build -a ARM -p ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-CTA9x4.dsc -t GCC47 -D EDK2_ARMVE_STANDALONE=0
5. Edit the ARM Versatile Express configuration file images.txt to declare the location of the UEFI firmware in NOR Flash
TOTALIMAGES: 5 ;Number of Images (Max : 32) NOR0UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE NOR0ADDRESS: BOOT ;Image Flash Address NOR0FILE: \SOFTWARE\bm_v209.axf ;Image File Name NOR1UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR1ADDRESS: 44000000 ;Image Flash Address NOR1FILE: \SOFTWARE\sec_uefi.bin ;Image File Name NOR1LOAD: 0 ;Image Load Address NOR1ENTRY: 0 ;Image Entry Point NOR2UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR2ADDRESS: 45000000 ;Image Flash Address NOR2FILE: \SOFTWARE\uefi.bin ;Image File Name NOR2LOAD: 45000000 ;Image Load Address NOR2ENTRY: 45000000 ;Image Entry Point NOR3UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR3ADDRESS: 46000000 ;Image Flash Address NOR3FILE: \SOFTWARE\kernel.bin ;Image File Name NOR3LOAD: 46000000 ;Image Load Address NOR3ENTRY: 46000000 ;Image Entry Point NOR4UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR4ADDRESS: 40000000 ;Image Flash Address NOR4NAME: BOOTSCRIPT ;Image Name NOR4FILE: \SOFTWARE\bootscr.txt ;Image File Name
6. To select second NOR Flash as a booting device, replace in the ARM Versatile Express file \SITE1\HBI0191B\board.txt:
SCC: 0x004 0x00001F09By:
SCC: 0x004 0x10001F09
7. Copy Build/ArmVExpress-CTA9x4/DEBUG_GCC47/FV/SEC_ARMVEXPRESS_EFI.fd to the ARM Versatile Express mass storage (available when the board is connected through USB to your host machine) under the folder SOFTWARE and name sec_uefi.bin. Example for cygwin:
cp Build/ArmVExpress-CTA9x4/DEBUG_GCC47/FV/SEC_ARMVEXPRESS_EFI.fd /cygdrive/e/SOFTWARE/sec_uefi.bin
8. Start the ARM Versatile Express board. You should read Waiting for firmware at 0x80000000 ... on the serial port.
9. Copy ARMVEXPRESS_EFI.fd at 0x80000000 with RealView Debugger
readfile,raw,nowarn "[EDK2_PATH]\Build\ArmVExpress-CTA9x4\DEBUG_GCC47\FV\ARMVEXPRESS_EFI.fd"=0x80000000
10. Resume the execution from RealView Debugger
1. Build ARM Versatile Express UEFI Firmware
build -a ARM -p ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-CTA9x4.dsc -t GCC47 -D EDK2_ARMVE_STANDALONE=0
2. Start the ARM Versatile Express board. You should read Waiting for firmware at 0x80000000 ... on the serial port.
3. Copy ARMVEXPRESS_EFI.fd at 0x80000000.
With RealView Debugger
readfile,raw,nowarn "[EDK2_PATH]\Build\ArmVExpress-CTA9x4\DEBUG_GCC47\FV\ARMVEXPRESS_EFI.fd"=0x80000000
With ARM DS-5
restore [EDK2_PATH]/Build/ArmVExpress-CTA9x4/DEBUG_GCC47/FV/ARMVEXPRESS_EFI.fd binary 0x80000000
Note: You can script this copy in DS-5 by adding the following lines in the text box "Execute debugger commands" of the 'Debugger' tab in "Debug Configurations":
interrupt if $pc==0x80000000 restore ~/tianocore/Build/ArmVExpress-CTA9x4/DEBUG_GCC47/FV/ARMVEXPRESS_EFI.fd binary 0x80000000 end
4. Resume the execution
The command line window needs to be the one from Visual Studio to get the environment variables required to get some development tools (the windows compiler for BaseTools and `nmake`). The EDK2 toolchain name for ARM RealView Compiler Toolchain under a Windows environment is `RVCT`. The EDK2 build system will automatically pick up the RVCT toolchain defined in your PATH. If you want to use a specific version, set the environment variable 'RVCT_TOOLS_PATH':
set RVCT_TOOLS_PATH=[YOUR_TOOLCHAIN_PATH]
The EDK2 toolchain name for ARM RealView under a Linux environment is `RVCTLINUX`. The EDK2 build system will automatically pick up the RVCT toolchain defined in your PATH. If you want to use a specific version, set the environment variable 'RVCT_TOOLS_PATH':
export RVCT_TOOLS_PATH=[YOUR_TOOLCHAIN_PATH]
The EDK2 toolchain name for ARM RealView under a Cygwin environment is `RVCTCYGWIN`. The EDK2 build system will automatically pick up the RVCT toolchain defined in your PATH. If you want to use a specific version, set the environment variable 'RVCT_TOOLS_PATH':
export RVCT_TOOLS_PATH=[YOUR_TOOLCHAIN_PATH]
The full ArmVe UEFI firmware can be written into NOR Flash to allow the entire boot sequence to be done after a cold boot.
build -a ARM -p ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-CTA9x4.dsc -t GCC47 -D EDK2_ARMVE_STANDALONE=1ARMVEXPRESS_EFI.fd is required to be copied into the ARM Versatile Express board:
cp Build/ArmVExpress-CTA9x4-Standalone/DEBUG_GCC47/FV/SEC_ARMVEXPRESS_EFI.fd /cygdrive/e/SOFTWARE/sec_uefi.bin cp Build/ArmVExpress-CTA9x4-Standalone/DEBUG_GCC47/FV/ARMVEXPRESS_EFI.fd /cygdrive/e/SOFTWARE/uefi.bin
ArmVE's UEFI supports booting Trustzone (two worlds: Secure and Normal Worlds) and No Trustzone (one world: the CPU remains in Secure World) supports. Trustzone support is enabled by Enabling SMC TZASC in the Test Chip SCC Register 1. This register can only be changed by editing the configuration file of your Versatile Express board: E:\SITE1\HBI0191B\board.txt Changing:
SCC: 0x004 0x10001F09
For:
SCC: 0x004 0x10003F09
The default entry in the ARM Boot Manager is defined by the PCDs:
- - gArmPlatformTokenSpaceGuid.PcdDefaultBootDescription|L"NorFlash"
- - gArmPlatformTokenSpaceGuid.PcdDefaultBootDevicePath|L"VenHw(E7223039-5836-41E1-B542-D7EC736C5E59)/MemoryMapped(0,0x46000000,0x462F0000)"
- - gArmPlatformTokenSpaceGuid.PcdDefaultBootArgument|"root=/dev/sda2 rootwait debug earlyprintk console=ttyAMA0,38400 mem=1G"
- - gArmPlatformTokenSpaceGuid.PcdDefaultBootType|1
PcdDefaultBootType defines the type of the image pointed by PcdDefaultBootDevicePath.
- - PcdDefaultBootDevicePath = 0 for an EFI Application
- - PcdDefaultBootDevicePath = 1 for a legacy kernel with ATAG support
- - PcdDefaultBootDevicePath = 2 for a kernel with Flat Device Tree (FDT) support
// Load FDT binary from the Firmware Volume (mapped at 0x80000000) #define LINUX_KERNEL L"MemoryMapped(11,0x80000000,0x6FEFFFFF)\\zImage.fdt" // Linux Kernel from a SD Card #define LINUX_KERNEL L"VenHw(621B6FA5-4DC1-476F-B9D8-52C557D81070)/HD(1,MBR,0x00000000,0xF9,0x3C8907)\\boot\\zImage.fdt" // Kernel from SATA HD - Partition 2 #define LINUX_KERNEL L"Acpi(PNP0A03,0)/Pci(0|0)/Pci(0|0)/Pci(5|0)/Pci(0|0)/Sata(0,0,0)/HD(2,MBR,0x00076730,0x1F21BF,0x1F21BF)\\boot\\zImage.fdt" // Kernel from NOR Flash #define LINUX_KERNEL L"VenHw(02118005-9DA7-443a-92D5-781F022AEDBB)/MemoryMapped(0,0x46000000,0x462F0000)"
1. Build UEFI
export EDK2_DSC=ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-CTA15-A7.dsc export EDK2_MACROS="-D ARM_BIGLITTLE_TC2=1" make -f ArmPlatformPkg/Scripts/Makefile
2. Change the Boot core - BootMon use A15-0 as a primary core while UEFI uses A7-0 Change from:
SCC: 0x700 0x00320003 ;CFGRW48 - Boot cluster and CPU (CA15[0])to:
SCC: 0x700 0x10320003 ;CFGRW48 - Boot cluster and CPU (CA7[0])
3. Configure the VExpress board with UEFI. Change the file SITE1/HBI0249A/images.txt on the VExpress mass-storage such as (note: the Boot Monitor image bm_v513r.axf might have a different name):
TITLE: Versatile Express Images Configuration File [IMAGES] TOTALIMAGES: 4 ;Number of Images (Max : 32) NOR0UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE NOR0ADDRESS: BOOT ;Image Flash Address NOR0FILE: \SOFTWARE\bm_v513r.axf ;Image File Name ;NOR0FILE: \SOFTWARE\bm_sram.axf ;Image File Name NOR1UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR1ADDRESS: 0x0d000000 ;Image Flash Address NOR1FILE: \SOFTWARE\uefi.bin ;Image File Name NOR1LOAD: 0xB0000000 NOR1ENTRY: 0xB0000000 NOR2UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR2ADDRESS: 0x0e000000 ;Image Flash Address NOR2FILE: \SOFTWARE\zImage ;Image File Name NOR2LOAD: 0 NOR2ENTRY: 0 NOR3UPDATE: AUTO ;IMAGE UPDATE:NONE/AUTO/FORCE NOR3ADDRESS: 0x0e800000 ;Image Flash Address NOR3FILE: \SOFTWARE\tc2.dtb ;Image File Name NOR3LOAD: 0
4. Start the board and type:
flash run uefi
The UEFI variables are stored in the NOR Flash of the Versatile Express. The UEFI variables are stored on the smaller block size partition of the NOR Flash - NOR Flash access is slow, using smaller block NOR Flash allows to get better performance than using larger block.
To erase the UEFI variables in the Non-Volatile storage, you need to restart the board to use ARM Boot Monitor (the ARM bootloader delivers with the ARM Versatile Express). On some platforms, Boot Monitor is enabled by changing the SCC used to switch NOR Flash mapping to boot either Boot Monitor or UEFI.
At the Bootmon prompt:
Base Area Size Blocks Block Size ---- --------- ------ ---------- 0x40000000 65280K 255 256K 0x43FC0000 256K 4 64K 0x44000000 65280K 255 256K 0x47FC0000 256K 4 64K Flash> erase range 0x43FC0000 Erasing flash Flash> erase range 0x47FC0000 Erasing flash Flash>
Different ARM platform models have different parameters. To ensure the parameters you are passing are supported by your model, list the supported parameters by using the argument '-l'. Example:
C:\Program Files\DS-5\bin>RTSM_VE_Cortex-A9_MPx4.exe -l # Parameters: # instance.parameter=value #(type, mode) default = 'def value' : description : [min..max] #---------------------------------------------------------------------------------------------- (...) motherboard.mmc.p_mmc_file="mmc.dat" # (string, init-time) default = 'mmc.dat' : MMCard filename motherboard.flashloader1.fname="" # (string, init-time) default = '' : Filename motherboard.flashloader1.fnameWrite="" # (string, init-time) default = '' : FilenameWrite motherboard.flashloader0.fname="" # (string, init-time) default = '' : Filename motherboard.flashloader0.fnameWrite="" # (string, init-time) default = '' : FilenameWrite (...)
The model supports various devices that UEFI already supports such as the CLCD, the MMC controller, the NOR Flash, the RTC, etc
To start the UEFI in the model, ensure the UEFI firmware is loaded in the NOR Flash mapped at 0x0 (generally NOR Flash 0). Note: At reset, the CPU always starts at 0x0.
1. Build UEFI
. edksetup.sh build -a ARM -p ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-RTSM-A9x4.dsc -t RVCTLINUX
2. Start the model with UEFI loaded in NOR Flash 0 (using Windows):
RTSM_VE_Cortex-A9_MPx4 -C motherboard.sp810_sysctrl.use_s8=1 -C motherboard.flashloader0.fname=Build\ArmVExpress-RTSM-CTA9x4\DEBUG_RVCT\FV\ARMVEXPRESS_EFI.fdOr start UEFI from the model Shell (using Linux):
model_shell -m RTSM_VE_Cortex-A9.so -C motherboard.sp810_sysctrl.use_s8=1 -C motherboard.flashloader0.fname=Build/ArmVExpress-RTSM-CTA9x4/DEBUG_RVCTLINUX/FV/ARMVEXPRESS_EFI.fd
As said earlier, the model supports MMC, you could even run UEFI Self Certifcation Test (SCT) on the Model: 1. Create a file that will contain the SCT Binaries
mkfs.vfat -C -n MMC_SD_CARD mmc.dat 131072Note: 131072 is the size is in kilobytes (125M * 1024)
2. Mount the file in the loopback device /dev/loop0:
mkdir fs sudo mount -o rw,loop=/dev/loop0,uid=`whoami`,gid=`whoami` mmc.dat fs
3. Copy the SCT binaries (ArmPlatformSCT folder) on the mounted filesystem (in the directory 'fs')
Note: If your platform firmware does not have EdkShell binary, you could copy the binary on the filesysem. The EdkShell binary is available in [EDK2_ROOT]/EdkShellBinPkg/FullShell/Arm/Shell_Full.efi
4. Unmount the filesystem
sudo umount fs
5. Start the model with the location of your mmc.dat file with the arguments: -C motherboard.mmc.p_mmc_file="mmc.dat"
6. Start EdkShell and Install SCT (refer to SCT documentation for more details).
By default UEFI on RTSM will boot Linux from Semihosting. When using Semihosting support, files are downloaded from the host machine. The file name for the Linux kernel can be found in ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-RTSM-A9x4.dsc:
gArmPlatformTokenSpaceGuid.PcdDefaultBootDevicePath|L"VenHw(C5B9C74A-6D72-4719-99AB-C59F199091EB)/zImage"
A default Device Path may also be specified using the PCD gArmPlatformTokenSpaceGuid.PcdFdtDevicePath. Example for a Device Tree downloaded from Semihosting:
gArmPlatformTokenSpaceGuid.PcdFdtDevicePath|L"VenHw(C5B9C74A-6D72-4719-99AB-C59F199091EB)/vexpress.dtb"
Note: The EFI Device Path Node 'VenHw(C5B9C74A-6D72-4719-99AB-C59F199091EB)' is Semihosting UEFI File System driver (located at ArmPkg/Filesystem/SemihostFs). By default the Semihosting support loads files from the location where the Fast Model has been started. The Semihosting support does not support folder; all files must be in the root of the default location.
A ARM core with Security Extension (case of most ARMv7 core) always starts in Secure World. But enabling Secure and Non-Secure worlds is not enough to have a Secure Platform, you must have Secure and Non-Secure memory. One way to have Secure and Non-Secure Memory regions is to use Trustzone controllers (see: http://www.arm.com/products/system-ip/controllers/trustzone-controllers.php). The Fast Model VExpress does not have Secure memory (this memory cannot be read from Non-Secure world).
If you want to experiment Secure and Non-Secure worlds on the Fast Model, you can use Non-Secure memory as Secure Memory. To enable both worlds, you must set the PCD gArmTokenSpaceGuid.PcdTrustzoneSupport to TRUE. ArmPlatformPkg/Sec module will be responsible to make the transition from Secure to Non-Secure World.
