Arm Versatile Express
|
|
=====================
|
|
|
|
Versatile Express (VE) family development platform provides an ultra fast
|
|
environment for prototyping Armv7 System-on-Chip designs. VE Fixed Virtual
|
|
Platforms (FVP) are simulations of Versatile Express boards. The platform in
|
|
Trusted Firmware-A has been verified with Arm Cortex-A5 and Cortex-A7 VE FVP's.
|
|
This platform is tested on and only expected to work with single core models.
|
|
|
|
Boot Sequence
|
|
-------------
|
|
|
|
BL1 --> BL2 --> BL32(sp_min) --> BL33(u-boot) --> Linux kernel
|
|
|
|
How to build
|
|
------------
|
|
|
|
Code Locations
|
|
~~~~~~~~~~~~~~
|
|
- `U-boot <https://git.linaro.org/landing-teams/working/arm/u-boot.git>`__
|
|
|
|
- `Trusted Firmware-A <https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git>`__
|
|
|
|
Build Procedure
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- Obtain arm toolchain. The software stack has been verified with linaro 6.2
|
|
`arm-linux-gnueabihf <https://releases.linaro.org/components/toolchain/binaries/6.2-2016.11/arm-linux-gnueabihf/>`__.
|
|
Set the CROSS_COMPILE environment variable to point to the toolchain folder.
|
|
|
|
- Fetch and build u-boot.
|
|
Make the .config file using the command:
|
|
|
|
.. code:: shell
|
|
|
|
make ARCH=arm vexpress_aemv8a_aarch32_config
|
|
|
|
Make the u-boot binary for Cortex-A5 using the command:
|
|
|
|
.. code:: shell
|
|
|
|
make ARCH=arm SUPPORT_ARCH_TIMER=no
|
|
|
|
Make the u-boot binary for Cortex-A7 using the command:
|
|
|
|
.. code:: shell
|
|
|
|
make ARCH=arm
|
|
|
|
|
|
- Build TF-A:
|
|
|
|
The make command for Cortex-A5 is:
|
|
|
|
.. code:: shell
|
|
|
|
make PLAT=fvp_ve ARCH=aarch32 ARM_ARCH_MAJOR=7 ARM_CORTEX_A5=yes \
|
|
AARCH32_SP=sp_min FVP_HW_CONFIG_DTS=fdts/fvp-ve-Cortex-A5x1.dts \
|
|
ARM_XLAT_TABLES_LIB_V1=1 BL33=<path_to_u-boot.bin> all fip
|
|
|
|
The make command for Cortex-A7 is:
|
|
|
|
.. code:: shell
|
|
|
|
make PLAT=fvp_ve ARCH=aarch32 ARM_ARCH_MAJOR=7 ARM_CORTEX_A7=yes \
|
|
AARCH32_SP=sp_min FVP_HW_CONFIG_DTS=fdts/fvp-ve-Cortex-A7x1.dts \
|
|
BL33=<path_to_u-boot.bin> all fip
|
|
|
|
Run Procedure
|
|
~~~~~~~~~~~~~
|
|
|
|
The following model parameters should be used to boot Linux using the build of
|
|
Trusted Firmware-A made using the above make commands:
|
|
|
|
.. code:: shell
|
|
|
|
./<path_to_model> <path_to_bl1.elf> \
|
|
-C motherboard.flashloader1.fname=<path_to_fip.bin> \
|
|
--data cluster.cpu0=<path_to_zImage>@0x80080000 \
|
|
--data cluster.cpu0=<path_to_ramdisk>@0x84000000
