RD-N2 Cfg2 Platform


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-N2 Cfg2 platform (which is a variant of the the RD-N2 platform) is a quad-chip platform in which four identical chips are connected through high speed CCG link. The CCG link is enabled through CMN-700 Coherent Multichip Link (CML) feature. RD-N2 Cfg2 in particular has the following hardware configuration on each chip.

  • 4xMP1 Neoverse N2 CPUs

  • CMN-700 interconnect (mesh size 6x6)

  • Multiple AXI expansion ports for I/O Coherent PCIe, Ethernet, offload

  • Arm Cortex-M7 for System Control Processor (SCP) and Manageability Control Processor (MCP)

The components integrated into this stack are described in Software Stack section.

Supported Features

RD-N2 Cfg2 platform software stack supports the following features.

Follow the links above for detailed information about the build and execute steps for each of the supported features.

Obtaining FVP

The latest version of the RD-N2 Cfg2 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 N2 Reference Design FVP” link to obtain the list of available Neoverse RD-N2 Reference Design FVPs.

  • Select a FVP build under the section “Download RD-N2” 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-N2 Cfg2 FVP executable is included in the downloaded installer and named as “FVP_RD_N2_Cfg2”. 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.
