CAN_CLK Setting in MBD for MPC57x 3.0 does not Match Data sheet

Dear All

For MPC5744P, the maximum CAN_CLK frequency must be 80MHz but the setting in mpc_clock_man_panther.c is 200MHz. Could you please explain this deviation?

Also, if I change the clock settings to 80MHz (using project to change the clock setting provided by NxP), the baudrate setting in the Simulink block Mask generates wrong code.

I assume for the Simulink Block the input frequency is assumed to be 200MHz (as shown in the panther code comments) but i reality we shall only use maximum 80. To get the correct baudrate, I have to multiply the baudrate by 2.5. Which is not possible in the dropdown menu of Simulink block.

Please provide a solution for this.

Hello abhishek.kumar@chassisbrakes.com‌,

Sorry for the late reply - I'll take a look at this and provide a fix this week so you don't have to manually change the baudrate.

Kind regards,

Razvan.
