Hi,

I try to test the SPI module on MPC5748G, but failed. The attachment is my project code.

First, I connnected the I/O as the "Qorivva Recipes for MPC574xG" .

After I ran the project, I checked the four signal.

The DSPI_3 SCK (PG4)is :64240622834578655.jpg
The DSPI_3 SOUT (PG2) is :

The DSPI_3 CS0 (PG3) is:

BUT !

The DSPI_3 SIN (PG5) is not correct :

Is there something that I did wrong ?

Can you help me check whether my project is correct ?

Thank you very much !
