[Warning] Wrong Configuration for PBRIDGE Clock in the MBD toolbox 3.0.0 - Devkit MPC5744P

Hello,

I am using the Devkit MPC5744P and I could check that the Model Based Design Toolbox 3.0.0 for Simulink has a wrong configuration for PBRIDGE clock.

By default, any model using the MBD toolbox presents the PBRIGDE clock frequency running on 100 MHz. I attached a model that verifies the clock configuration and a Freemaster file in order to make easier the visualization.

However the MPC5744P Reference Manual states that the maximum frequency configuration for PBRIGDE clock is 50 MHz, as can be checked below.

Hello rafael.barbosa@chassisbrakes.com,

I have attached here the new PEBRIDGE config.

The path for the file to be replaced is the following:

{TOOLBOX_DIR}\mbdtbx_mpc574x\src\c_library

Kind regards,

Razvan.

Hello rafael.barbosa@chassisbrakes.com‌,

I will investigate this issue and provide a fix for the correct value of PEBRIDGE clock.

Thank you for pointing this out!

Kind regards,

Razvan.
