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.
The BCM5719 also connects to the BMC via RGMII NC-SI, providing network connectivity to the BMC.
Firmware
All Raptor systems shipped after May 10, 2021 use the open-source Ortega firmware for the BCM5719 device.
Older devices that shipped with the proprietary firmware can be updated to the open source firmware by following the instructions on github or by using the following command:
[user@hostname ~]$ sudo fwupdmgr switch-branch
Once on the open source firmware branch, fwupd will will provide updates using the following command:
[user@hostname ~]$ sudo fwupdmgr update

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.
