Broadcom BCM958402M2 (Cortex-M7)

Overview

The Broadcom bcm958402m2_m7 board utilizes the Viper BCM58402_M7 SoC to provide support for PCIe offload engine functionality.

Hardware

The bcm958402m2_m7 is a PCIe card with the following physical features:

  • PCIe Gen4 interface

  • RS232 UART (optionally populated)

  • JTAG (optionally populated)

Supported Features

The Broadcom bcm958402m2_m7 board configuration supports the following hardware features:

Interface

Controller

Driver/Component

NVIC

on-chip

nested vectored interrupt controller

UART

on-chip

Compatible with UART NS16550

Other hardware features are not supported by the Zephyr kernel.

The default configuration can be found in the defconfig file:

boards/arm/bcm958402m2_m7/bcm958402m2_m7_defconfig

Programming and Debugging

Flashing

The flash on board is not supported by Zephyr at this time. Board is booted over PCIe interface.

Debugging

The bcm958402m2_m7 board includes pads for soldering a JTAG connector. Zephyr applications running on the M7 core can also be tested by observing UART console output.
