Forum Post: RE: How to config SRIO with this certain situation?

Hi David,

Some questions about your HW:

1. So you are using 3 C6678 EVMs?
2. How do you physically have them connected to each other?

Some questions about your SW:

1. Are you using example code included in the MCSDK? If so, which example?
2. How are you modifying the code to change the mode you are using and accounting for the change in the example?
3. Can you provide the console output of your successful and failed runs?

 If you specifically would like to use lane A and lane B, modes 0 or 2 should work for you. To address your question about mode 4 working, it's possible that the code is set up to work on port 0 in mode 4, which then auto-negotiates down to a 1x port when it realizes that the 4x port is not available.

Mode 0 might not work due to something that you have or have not changed in the code to accommodate this change. I'll be able to provide more insight once I know more about your HW and SW setup.

Thanks,

Clinton
