1028 DSPI communication clock has a significant delay

[Eddy1]

hi

Recently, I have been using DSPI as the host for slave communication, but I found that the communication speed is very slow. Through logic analysis, I found that when CS is lowered by 2ms, the clock sends every 1ms, and 1ms corresponds to SPI communication which is too slow. Do you have any optimization solutions? The currently used edge bsp5.10

Would you share which pins you are using and log when you access the interface.

Thank you for your response. I have solved the issue by adjusting the timing parameters of the SPI.
