The platform port documents are not very standardised right now and they don't integrate properly into the document tree so: 1) Make sure each port has a proper name and title (incl. owner) 2) Correct use of headings, subheadings, etc in each port 3) Resolve any naming conflicts between documents Change-Id: I4c2da6f57172b7f2af3512e766ae9ce3b840b50f Signed-off-by: Paul Beesley <paul.beesley@arm.com>

Arm Versatile Express
|
|
=====================
|
|
|
|
Versatile Express (VE) family development platform provides an
|
|
ultra fast environment for prototyping arm-v7 System-on-Chip designs.
|
|
VE Fixed Virtual Platforms (FVP) are simulations of Versatile Express boards.
|
|
The platform in arm-trusted-firmware 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>`__
|
|
|
|
- `arm-trusted-firmware <https://github.com/ARM-software/arm-trusted-firmware>`__
|
|
|
|
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
|
|
arm-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
