RD-Fremont platform software user guide
Introduction
RD (Reference Design) is a collection of resources to provide a representative view of typical compute subsystems that can be designed and implemented using specific generations of Arm IP. RD-Fremont is the first RD platform with Realm Management Extension (RME) support and is based on the following hardware configuration.
32xMP1 Neoverse Poseidon-V cores with Direct Connect and 2MB of dedicated, private L2 cache for each core.
CMN-Cyprus interconnect with 7x6 mesh network.
Multiple AXI expansion ports for I/O Coherent PCIe, Ethernet, offload
Arm Cortex-M55 processor for Runtime Security Subsystem (RSS) to support Hardware Enforced Security (HES)
Arm Cortex-M7 for System Control Processor (SCP) and Manageability Control Processor (MCP)
Arm Cortex-M55 processor for Local Control Processor (LCP) for local power management of each Application Processor (AP)
The Fixed Virtual Platform of RD-Fremont config supports 16xMP1 Neoverse Poseidon-V CPUs.
This document is a user guide on how to setup, build and run the RD-Fremont software stack on the Fixed Virtual Platform. The components integrated into this stack is described in the software stack introduction page. An overview of the platform’s boot flow is described in boot flow overview page.
Setting up the Host Machine and Syncing the software stack
Host Machine requirements and the necessary steps to be followed to sync the software stack are listed on ‘Setup Workspace’ page.
Obtaining the RD-Fremont FVP
The latest version of the RD-Fremont fixed virtual platform (FVP) can be downloaded from the Arm Ecosystem FVPs page. On this page,
Navigate to “Neoverse Infrastructure FVPs” section.
Click on “Neoverse Fremont Reference Design FVP” link to obtain the list of available Neoverse RD-Fremont Reference Design FVPs.
Select a FVP build under the section “Download RD-Fremont” based on the host machine architecture.
For AArch64 host machine, click “Download Linux - Arm Host (DEV)” link.
For x86-64 host machine, click “Download Linux” link.
The RD-Fremont FVP executable is included in the downloaded installer and named as “FVP_RD_Fremont”. Follow the instructions of the installer and setup the FVP. The installer, by default, selects the home directory to install the FVP. To opt for different directory than the one selected by the installer, provide an absolute path to that directory when prompted for during the FVP installation process.
