L1100 - segments overlap 0xFFFA and 0xFFFE

[checkers]

I really don't know where these definitions come from.

Can someone explain why segment FFFA of 6 bytes overlaps segment FFFE of 2 bytes?

Not that I can't count, but I don't know why the Processor Expert defined these two segments on the same space.

Which peripheral did I add that caused PE to define ivVreset at 0xFFFE? None of the peripheral definitions mention this address. However, the definition shows up in Vectors.c which is generated by PE.

/*lint -save  -e950 Disable MISRA rule (1.1) checking. */

static const tIsrFunc _ResetVectorTable[] @0xFFFAU = { /* Reset vector table */

/*lint -restore Enable MISRA rule (1.1) checking. */

  /* Reset handler name                    Address Name           Description */

  &_EntryPoint,                         /* 0xFFFA  ivVcop         unused by PE */

  &_EntryPoint,                         /* 0xFFFC  ivVclkmon      unused by PE */

  &_EntryPoint                          /* 0xFFFE  ivVreset       used by PE */

};

It looks like 0xFFFA is ResetVectorTable

I just don't know how to fix this.

There is also this definition ...

extern near void _Startup(void);

/* reset interrupt service routine */

void (* near const _vect[])() @0xFFFE = { /* RESET Interrupt vector */

_Startup

};

Can I move this to another location?

How would I do that? Which address is appropriate for Startup?

Hello

I would recommend to delete the lines:

void (* near const _vect[])() @0xFFFE = { /* RESET Interrupt vector */

_Startup

};

If you are building a Processor Expert application you should let Processor Expert handle the generation of the vector table.

The application entry point for a Processor Expert generated application is _EntryPoint. This function initializes some hardware devices and then calls _Startup.

Thanks,  but the problem with that is that ALL of the code was generated by Processor Expert and it will overwrite that change the next time I run make.

Is this a bug in PE maybe?

I am too new to CodeWarrior.

Hello

There might be some special bean that you have added to your project and that creates this additional

table.

void (* near const _vect[])() @0xFFFE = { /* RESET Interrupt vector */

_Startup

};

I am unable to reproduce that locally, so I would recommend you to submit a service request through our on line support web page for that.

Make sure to attach a project reproducing the trouble.
