How to forward Broadcast Frames to QNX (A72) in case of QNX+RTOS use case with Ethernet Firmware, note all my network operations were managed at QNX.
Issue:
By default, all broadcast frames will be forwarded to Ethernet Firmware (server/master running on MCU2_0 core), and Ethernet Firmware will share with other client cores via Inter-core Virtual Ethernet communication as shown in below diagram, for more details refer to User Guide.
But, on the QNX side there is no support for Inter-core Virtual Ethernet communication. So, the broadcast frames can't receive on the QNX side.
Resolution:
Considering that all network operations are managed on the QNX side, we can forward all broadcast frames to QNX. In this case, other client cores and Ethernet Firmware can't receive broadcast frames.
Steps to follow:
# ip maddr add FF:FF:FF:FF:FF:FF dev eth1
