aharoune — Sun, 29 Sep 2024 19:10:08 GMT

Hello All.

I have the following connections in my project.

I want to be able to configure the NXP switch so that any messages to be sent from Port 2 to be routed to Port 3 and 4.
and any messages sent through Port 3 to be routed to Port 2 and 4. and any messages sent through Port 4 to be routed to Port 2 and 3.
Basically I want to be able to use the Connectors on Port 2 and 3 to route and sniff data to and from EQ6H.

I want to know the SPI commands and static configurations to be configured to the NXP switch.

Hello aharoune,

I apologize for late response. There are two tools available for configuring SJA1105:

SDK SJA1110 contains basic support of SJA1105
Python3 tools SJA1105X_CONFIG-GENTOOL and Python2 tools SJA1105X-DEVICE-TOOLS

For basic switch functionality, you need to setup L2 Forwarding Table. Please related chapters in Software user manual for SJA1105P, SJA1105Q, SJA1105R, SJA1105S and AH1704 SJA1105PQRS Application Hints.

Best regards,
