Dear Support,

With Stream example:
- can we loopback channels SFP0 to SFP1?
- Can you confirm that the output file is Data.bin?
- What is the structure of this binary file?

1) Can we loopback SFP0 to SFP1?

No, you can only loop channels by pairs to produce a 32 bit data path. So SFP01 can loop back to the other SFP01, or to SFP23.

2) Is the output file Data.bin

Yes

3) What is the format?

It is a packet file, so the headers are included in the stream. The format of the data is one 32 bit channel in each block.

Thanks Chris.

The first answer is not clear:
No, you can only loop channels by pairs to produce a 32 bit data path. So SFP01 can loop back to the other SFP01, or to SFP23.

What do you mean by "SFP01 can loop back to the other SFP01"?
How can we connect SFP01 to SFP01?

The example lets you configure that setup. You may be right that the physical board doesn't let you set it up.
