Sorry for not replying to @marioruiz for a long time as there is a problem with U280 power, and the original topic is closed, so I create this.
After I download .xclbin of XUP to U280 (two interfaces are connected to the switch via two qsfp28 Tansceiver modules and a cable), and use the vnx-basic.ipynb to configure the FPGA, there is only one of the two network interfaces is UP.
The make command:
make all DEVICE=<full platform path> INTERFACE=<interface number> DESIGN=<design name>
the result of vnx-basic.ipynb is
Link interface 0 {'cmac_link': True}; link interface 1 {'cmac_link': False}
Then I adjust the interface connecting scheme from 1 to 2:
The result of vnx-basic.ipynb doesn’t change.
So the problem occurs in interface 1. Are there some solutions?
Thanks a lot for your help.
