MPC5777C DSPI not working using MPC5777M example

Hi.

I tried to use the example Example MPC5777M DSPI_SimpleTXRX S32DS porting to MPC5777C SPI but I didn`t have success.

(DSPI_A instead of DSPI_0 and DSPI_B instead DSPI_2)

 

Unfortunately, no data is received by DSPI_A or DSPI_B.

Using the MPC57XXX Motherboard on MPC5777C-416DS and a logical analyzer, I am monitoring the PM7,PM8,PM6, PM13 to check the DSPI_A activity and PO2,PM15,PO0 and PM10 to check DSPI_B activity.

 

The wiring connection:

SINA     PM7 -> PO2   SOUTB 

SOUTA PM8 -> PM15 SINB

SCKA PM6   -> PO0 SCKB

PCSA0 PM13 -> PM10 PCSB0

 

Is there any modification on example to work on MPC5777C ? (clock configuration, pin assignment and etc )

Is that pin assignment correct ?

 

Thanks

Thiago.
