| 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]_. |
