MPC5746C.h 5.0.1 missing CAN buffers

[cholland]

Hi,

I tried updating the MPC5746C.h file and noticed the message buffers are missing.

CAN_0_MB_tag MB[64];  is not in MPC5746C.h revision 5.0.1.

Seems odd, since revision 4.0.1 seemed to update to the correct number.

It's either that, or I have an edited version. 

I got the version from the following

    MPC5 software example list    

       MPC5746C

            Example MPC5746C PIT ISR GHS614  <-- MPC5746C.h Version 5.0.1

* 4.0.1 M.D. 07-JUL-16 -Corrected number of CAN Message *
*                                      Buffers from 64 to 96 b *
* 5.0 I.T. 03-MAY-17 -Generated from updated RDP Rev5

I am using MPC57465C.h revision 4.0.0

Is there an official repository that I can get the latest and greatest MPC5746C.h file?

Thank you,

P.S. I also noticed that the CSL flag is missing in revision 4.0.0. I went ahead and added it.

typedef union STM_CR_union_tag { /* STM Control Register */
vuint32_t R;
struct {
vuint32_t :16;
vuint32_t CPS:8; /* Counter Prescaler. */  /* <-- Missing in Revision 4.0.0 */
vuint32_t :3;
vuint32_t CSL:1; /* Clock Select. */
vuint32_t :2;
vuint32_t FRZ:1; /* Freeze. */
vuint32_t TEN:1; /* Timer counter Enabled. */
} B;
} STM_CR_tag;

I am attaching newest header file for MPC5746C (rev6.0). Hope it helps

[davidtosenovjan]

Hi,

I have asked for generating of new header file as current RM is 6.0 and header file should be aligned with that.

Also I have mentioned issue with CAN buffers. I will attach new header file as soon as possible.
