BCM5719

Overview

The BCM5719 is the NIC integrated into the Talos™ II and Blackbird™ systems. It is based on the wildly popular NetXtreme architecture, and there have been efforts to document the internal operation of devices based on that architecture.

All Raptor systems shipped after May 10, 2021 use the open-source Ortega firmware for the BCM5719 device.

The BCM5719 also connects to the BMC via RGMII NC-SI, providing network connectivity to the BMC.

Resources

• Official Ortega firmware shipped on Raptor systems
• Register manual
• Proprietary Broadcom firmware image for recovery of bricked Talos™ II on-board NICs. This image is considered deprecated by Raptor, and Raptor strongly recommends the use of the open-source Ortega firmware instead of the proprietary Broadcom firmware. Note that the two MAC addresses inside this image must be changed to match the MAC addresses on your particular Talos™ II system; failure to do so could potentially cause serious network issues, including harm to other computers and/or users on any network(s) attached to the Broadcom network ports.
