| 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 | |
| +-----------+------------+--------------------------------------+ |

| 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. |
