Hi expert!

I am planning to use the cpsw of main domain to use the cpsw0 9 ports switch.I found that there isn't any device tree file which enable the cpsw of main domain.Is there any guiding file for me to edit a device tree file for enable cpsw switch and mac?

and in the  <J721E DRA829/TDA4VM Processors Silicon Revision 1.1 Texas Instruments Families of Products>, it says that the cpsw0 is 5 ports switch.

but later it says it is 9-port switch. what does it mean?

    Hi,

    CPSW 9G has a virtual driver in Linux. All initialization is done by Ethernet FW running on Main R5F 2_0 which is loaded by remoteproc. There is no DT for CPSW 9G.

    The reference to 5 ports is a documentation error (it's referring to the CPSW 5G switch on DRA821)

    Regards
