Broadcom BCM958401M2¶
Overview¶
The Broadcom BCM958401M2 board utilizes the Valkyrie BCM58400 SoC to provide support for PCIe offload engine functionality.
Hardware¶
The BCM958401M2 is a PCIe card with the following physical features:
PCIe Gen3 interface
RS232 UART (optionally populated)
JTAG (optionally populated)
Supported Features¶
The Broadcom BCM958401M2 board configuration supports the following hardware features:
Interface |

Connections and IOs¶
Programming and Debugging¶
Flashing¶
The flash on board is not supported by Zephyr at this time. Board is booted over PCIe interface.
Debugging¶
The bcm958401m2 board includes pads for soldering a JTAG connector. Zephyr applications running on the M7 core can also be tested by observing UART console output.
