Overview

The Broadcom bcm958402m2/bcm58402/m7 board utilizes the Viper BCM58402_M7 SoC to provide support for PCIe offload engine functionality.

Hardware

The bcm958402m2/bcm58402/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/bcm58402/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 have not been enabled yet for this board.

The default configuration can be found in :zephyr_file:boards/brcm/bcm958402m2/bcm958402m2_bcm58402_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/bcm58402/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.
