Arm FVP BaseR AEMv8-R
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.
