Problem with DSPI sample for MPC5777M

Hello all,

I am going to use DSPI links. I am trying to use MPC5777M DSPI sample available in NXP community on a MPC57XX_MB and MPC5777M_512DS.

I have put a breakpoint on the while testing the SR and I have seen that DSPI_0 SR.TCF is 1 and DSPI_2 SR.TCF stay to 0.

The POPR register are set to 0 for both DSPI.

Have you an idea ?

By the way, no modification has been done in the code.

Thanks a lot

Hello

After code deep analysis, I have found that the comment in the main.c header is wrong.

the line : * EVB connection: P18.12 to P14.13 (CS_0)

must be replaced by * EVB connection: P8.12 to P14.13 (CS_0)

By connecting the CS_0 to PA[12] the sample is working well.
