Issue of Stream loss when having Two different Stream in SJA1110 and S32

[Abrar_23]

Hello @PavelL
@alejandro 
In FRER where i am adding RTAG_TYPE as 0xF1C1
so i am planning to Integrate FRER in CAN and also planning to add FRER for each CAMERA frames also but same RTAG_TYPE as 0xF1C1 whether that will be a Problem ?
and one more issue when after booting up the hardware at first initially if i start to send CAN frames my CAMERA feed is not coming and CAMERA frame is not coming and vice versa condtion is happening when the reboot if i start to send CAMERA Frames the CAN frames are not coming
so this was due to configuring previous configuration so what might be the root cause

Hello @Abrar_23,

I don't fully understand your problem, you added the tags of SJA1110 but you are talking about CAN protocol, which is not supported by the SJA1110. However I don't see how FRER (Frame Replication and Elimination for Reliability) could cause problems in your implementation, but this could depend on the speed you are using, since replicating frames uses network bandwidth.

Hello @alejandro_e 

Sorry for giving the uncleared understanding 

So S32 Process is internally running which will do my CAN operation for for CAN Pacnet Generation. So you can just not consider about s32 implementation the main motive is in FRER in SJA1110.

So I am having a camera 30mbps at speed it's running 

So may I know brief about how much bandwidth utilization will be done during FRER Integration

May I know the network bandwidth exact numbers or something 

How the system will be utilizing bandwith because i too sense that the packet loss root cause when we are tryinv to run both stream need to Transmit parllely CAN and CAMERA

Hello @Abrar_23,

The used bandwidth will depend on the configuration you are using and the  topology of your network, the number of frames you replicate and the size of the frames. in case your network only has the SJA1110 and the camera you mention, the use of FRER does not offer that much advantages, it offers important improvements in networks with several paths to the same nodes. Have you tested your camera without FRER? to check if this solves the other problem?

Thanks
