why there is only port 2 is up when i want to use the mode of 4x25G on N3000

After updating 4x25G related .bin file into N3000 and rsu the bmc , when i checked the information with command of "sudo fpgainfo phy", port 0, port 1 and port 3 were all down and only port 2 was up. However, in the case of 8x10G, after updating binary file, all ports were up automatically without any other operations when checking the info.

Then my question is why there is only port 2 is up in 4x25G mode? And any solutions to make all ports up?

Thanks!

    Which OPN are you using?

    BD-NFV-N3000-1 :Production 10 GbE

    OR

    BD-NVV-N3000-2: Production 25 GbE

    Did you program the BD-NFV-N3000-1 card with 4x25G image?

      Thanks for your reply , the BD I used is N3000-2 I think.
      The question has been solved after an external traffic generator was used.
      The reason may be when i use 8x10 G mode the cable was linking QSFP A with QSFP B for a loop so the links were all up；while in the case of 4x25 G, the QSFP B is disabled actually, but the cable still was linking the QSFP A with QSFP B.
      If I am wrong please let me know.
      Thank for your reply again!

        Maybe I was wrong on the understanding of 8x10G.

        I found my BC is N3000-2 after checking my order，which means the BC is not supported for the mode of 8x10 G. And all ports were up in 8x10G may be only an illusion or a good fortunate.
