Jetson Nano spi clock problem

I have a problem about using jetson nano’s spi. I was using jetpack 4.6 and enable the spi by Jetson-io, and had passed the loop test.

If I connect to my equipment, its clock will be like the figure below (the blue one is clock).

However, if it were not connected to the device, the shape will be normal (the blue one is clock).

How can I fix it or where did I make a mistake? I changed several spi device and all of them looks weird.
Here was how I set up my equipment. Thanks for your help.

Sorry for the late response, our team will do the investigation and provide suggestions soon. Thanks
