Arm FVP BaseR AEMv8-R

Debug with Arm DS

Overview

This board configuration uses Armv8-R AEM FVP 1 to emulate a generic Armv8-R 2 64-bit hardware platform.

Fixed Virtual Platforms (FVP) are complete simulations of an Arm system, including processor, memory and peripherals. These are set out in a “programmer’s view”, which gives you a comprehensive model on which to build and test your software.

The Armv8-R AEM FVP is a free of charge Armv8-R Fixed Virtual Platform. It supports the latest Armv8-R feature set. Please refer to FVP documentation page 3 for more details about FVP.

To Run the Fixed Virtual Platform simulation tool you must download “Armv8-R AEM FVP” from Arm developer 1 (This might require the user to register) and install it on your host PC.

Hardware

Supported Features

The following hardware features are supported:

Interface	Controller	Driver/Component
GICv3	on-chip	interrupt controller
PL011 UART	on-chip	serial port
Arm GENERIC TIMER	on-chip	system clock

The kernel currently does not support other hardware features on this platform.

When FVP is launched with -a, --application FILE option, the kernel will be loaded into DRAM region [0x0-0x7FFFFFFF]. For more information, please refer to the official Armv8-R AEM FVP memory map document 4.

Devices

System Clock

This board configuration uses a system clock frequency of 100 MHz.

Serial Port

This board configuration uses a single serial communication channel with the UART0.

Programming and Debugging

Use this configuration to build basic Zephyr applications and kernel tests in the Arm FVP emulated environment, for example, with the Synchronization Sample:

# From the root of the zephyr repository
west build -b fvp_baser_aemv8r samples/synchronization

This will build an image with the synchronization sample app. To run with FVP, first set environment variable ARMFVP_BIN_PATH before using it. Then you can run it with west build -t run.

export ARMFVP_BIN_PATH=/path/to/fvp/directory
west build -t run

Debugging

Refer to the detailed overview about Application Debugging. See Debug with Arm DS for how to debug with Arm Development Studio 5.
