Board Variants

The following board targets are available:

fvp_base_revc_2xaem/v8a - ARMv8-A (64-bit) with Cortex-A53 cores
fvp_base_revc_2xaem/v8a/smp - ARMv8-A SMP (4 cores)
fvp_base_revc_2xaem/v8a/smp/ns - ARMv8-A SMP Non-Secure
fvp_base_revc_2xaem/v9a - ARMv9-A (64-bit) with Cortex-A510 cores
fvp_base_revc_2xaem/v9a/smp - ARMv9-A SMP (4 cores)
fvp_base_revc_2xaem/v9a/smp/ns - ARMv9-A SMP Non-Secure
fvp_base_revc_2xaem/a320 - ARMv9.2-A with Cortex-A320 configuration

Cortex-A320 Variant:

The fvp_base_revc_2xaem/a320 variant provides Cortex-A320 specific FVP configuration with:

ARMv9.2-A architecture compliance
Enhanced cryptographic extensions (SHA3, SHA512, SM3, SM4)
Advanced memory tagging (MTE Level 3)
QARMA3 Pointer Authentication
Optimized cache configuration for Cortex-A320

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.

Known Problems or Limitations

Programming and Debugging

Environment

First, set the ARMFVP_BIN_PATH environment variable before building. Optionally, set ARMFVP_EXTRA_FLAGS to pass additional arguments to the FVP.

export ARMFVP_BIN_PATH=/path/to/fvp/directory

Programming

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

# From the root of the zephyr repository
west build -b fvp_base_revc_2xaem/v8a samples/synchronization

This will build an image with the synchronization sample app for ARMv8-A. Then you can run it with west build -t run.

For ARMv9-A variants:

# From the root of the zephyr repository
west build -b fvp_base_revc_2xaem/v9a samples/synchronization

For Cortex-A320 variants:

# From the root of the zephyr repository
west build -b fvp_base_revc_2xaem/a320 samples/hello_world

For SMP variants:

# From the root of the zephyr repository
west build -b fvp_base_revc_2xaem/v8a/smp samples/synchronization

For SMP Non-Secure variants with TF-A:

# From the root of the zephyr repository
west build -b fvp_base_revc_2xaem/v8a/smp/ns samples/synchronization

Running Zephyr at EL1NS

In order to run Zephyr as EL1NS with CONFIG_ARMV8_A_NS, you’ll need a proper Trusted Firmware loaded in the FVP model.

The Arm TF-A for FVP can be used to run Zephyr as preloaded BL33 payload.

Checkout and Build the TF-A:

git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git --depth 1
cd trusted-firmware-a/
make PLAT=fvp PRELOADED_BL33_BASE="0x88000000" all fip

then export the ARMFVP_BL1_FILE and ARMFVP_FIP_FILE environment variables:

export ARMFVP_BL1_FILE=<path/to/tfa-a/build/fvp/release/bl1.bin>
export ARMFVP_FIP_FILE=<path/to/tfa-a/build/fvp/release/fip.bin>

Migration from Legacy Board Names

The legacy board name fvp_base_revc_2xaemv8a has been replaced with the unified fvp_base_revc_2xaem/v8a naming. Update your build commands:

Old: west build -b fvp_base_revc_2xaemv8a
New: west build -b fvp_base_revc_2xaem/v8a

The legacy board name remains supported for backward compatibility.
