Arm Versatile Express
|
||
|
|
=====================
|
||
|
|
|
||
|
|
The vexpress_* board configuration supports the following platforms:
|
||
|
|
|
||
|
|
* FVP_Base_RevC-2xAEMvA
|
||
|
|
* Juno development board
|
||
|
|
|
||
|
|
Fixed Virtual Platforms
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
The Fixed Virtual Platforms (FVP) are complete simulations of an Arm system,
|
||
|
|
including processor, memory and peripherals. They are set out in a "programmer's
|
||
|
|
view", which gives a comprehensive model on which to build and test software.
|
||
|
|
|
||
|
|
The supported FVPs are available free of charge and can be downloaded from the
|
||
|
|
Arm developer site [1]_ (user registration might be required).
|
||
|
|
|
||
|
|
Supported features:
|
||
|
|
|
||
|
|
* GICv3
|
||
|
|
* Generic timer
|
||
|
|
* PL011 UART
|
||
|
|
|
||
|
|
The default configuration assumes that U-Boot is bootstrapped using a suitable
|
||
|
|
bootloader, such as Trusted Firmware-A [4]_. The u-boot binary can be passed
|
||
|
|
into the TF-A build: ``make PLAT=<platform> all fip BL33=u-boot.bin``
|
||
|
|
|
||
|
|
The FVPs can be debugged using Arm Development Studio [2]_.
|
||
|
|
|
||
|
|
Juno
|
||
|
|
----
|
||
|
|
|
||
|
|
Juno is an Arm development board with the following features:
|
||
|
|
|
||
|
|
* Arm Cortex-A72/A57 and Arm Cortex-A53 in a "big.LITTLE" configuration
|
||
|
|
* A PCIe Gen2.0 bus with 4 lanes
|
||
|
|
* 8GB of DRAM
|
||
|
|
* GICv2
|
||
|
|
|
||
|
|
More details can be found in the board documentation [3]_.
