Bug in HWREG macro since HALCoGen 3.04.00

Other Parts Discussed in Thread: HALCOGEN

Hello,

I found a bug in the HWREG macro in hw_reg_access.h with HALCoGen 3.04.00.

Old definition:

#define HWREG(x)                                                              \
        (*((volatile unsigned long *)(x)))

New definition:

#define HWREG(x)                                                              \
        (*((volatile uint64 *)(x)))

unsigned long is 32bit. This leeds to many wrong initialised registers in emac and mdio and therefore to a not functional ethernet.

There is also a problem for me to fix it, because if I change uint64 to uint32 (it will work then) and generate a new code with HALCoGen my changes were lost.

Any suggestions how to solve it?

Best regards

Christian

    Hi Christian,

            Just to add to Prathap's comment.   You can have a try to use the hw_reg_access.h file in the old version to replace the same name file in the new version. Maybe that will solve your problem. 

             The path of the file is:

                 \HALCoGen\v3.03.01\drivers\TMS570LS3137ZWT\EMAC570v000

                \HALCoGen\v03.04.00-Alpha\drivers\TMS570LS3137ZWT\EMAC570v000

             Hope that this may help you.

    Best Regards,
    Shelford

    Hi.

    Thanks for the suggestions. This can be a solution until fixed HALCoGen will be released. BTW: Is there a release date already known?

    Best Regards

    Hi Christian,

          HALCoGen V3.04.00 is just released in January 2013. Maybe you need to wait some time for a new version.  I will keep you updated  when we have the specific schedule.  Thanks.  Have a good day.

    Best Regards,
