| 12 | Fixed Virtual Platforms |
| 13 | ----------------------- |
| 14 | |
| 15 | The Fixed Virtual Platforms (FVP) are complete simulations of an Arm system, |
| 16 | including processor, memory and peripherals. They are set out in a "programmer's |
| 17 | view", which gives a comprehensive model on which to build and test software. |
| 18 | |
| 19 | The supported FVPs are available free of charge and can be downloaded from the |
| 20 | Arm developer site [1]_ (user registration might be required). |
| 21 | |
| 22 | Supported features: |
| 23 | |
| 24 | * GICv3 |
| 25 | * Generic timer |
| 26 | * PL011 UART |
| 27 | |
| 28 | The default configuration assumes that U-Boot is bootstrapped using a suitable |
| 29 | bootloader, such as Trusted Firmware-A [4]_. The u-boot binary can be passed |
| 30 | into the TF-A build: ``make PLAT=<platform> all fip BL33=u-boot.bin`` |
| 31 | |
| 32 | The FVPs can be debugged using Arm Development Studio [2]_. |
| 33 | |
| 34 | Juno |
| 35 | ---- |
| 36 | |
| 37 | Juno is an Arm development board with the following features: |
| 38 | |
| 39 | * Arm Cortex-A72/A57 and Arm Cortex-A53 in a "big.LITTLE" configuration |
| 40 | * A PCIe Gen2.0 bus with 4 lanes |
| 41 | * 8GB of DRAM |
| 42 | * GICv2 |
| 43 | |
| 44 | More details can be found in the board documentation [3]_. |
