The vexpress_* board configuration supports the following platforms:
- FVP_Base_RevC-2xAEMvA
- FVP_BaseR_AEMv8R
- Juno development board
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 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].
