Arm Versatile Express

The vexpress_* board configuration supports the following platforms:

  • FVP_Base_RevC-2xAEMvA
  • FVP_BaseR_AEMv8R
  • 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].
