Out of allocation space in segment ROM at address 0xFB8F - in a HCS08 QG8

[gusnavarro]

Hi !

I was working with my microcontroller and when I compiled it i got

Out of allocation space in segment ROM at address 0xFB8F - in a HCS08 QG8

Is this has to do due to a license issue ?

Can i do something else to "have" more space to add more code into my microcontroller ?

Project.prm file here :

Out of allocation space in segment ROM at address 0xFB8F - in a HCS08 QG8

/* This is a linker parameter file for the mc9s08qg8 */

NAMES END /* CodeWarrior will pass all the needed files to the linker by command line. But here you may add your own files too. */

SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */

    Z_RAM                    =  READ_WRITE   0x0060 TO 0x00FF;

    ROM1                     =  READ_ONLY    0xFFC0 TO 0xFFCF;

END

PLACEMENT /* Here all predefined and user segments are placed into the SEGMENTS defined above. */

    DEFAULT_RAM,                        /* non-zero page variables */

                                        INTO  RAM;

    DEFAULT_ROM,

                                        INTO  ROM; /* ,ROM1: To use "ROM1" as well, pass the option -OnB=b to the compiler */

    _DATA_ZEROPAGE,                     /* zero page variables */

    MY_ZEROPAGE                         INTO  Z_RAM;

END

STACKSIZE 0x80

VECTOR 0 _Startup /* Reset vector: this is the default entry point for an application. */

Please advice

Thanks Gus!

Unless there are mistakes in the various definitions, all this means is that your code is too big for this device.

[gusnavarro]

This device can handle more code that I put.

No mistakes in definitions.

Hi Gus,

I just noticed this question was also answered in SR1-3849004261.

per your feedback. your question got answered.

I post the solution here in case it can also help other customers who have the similar issue. thanks for your understanding.

"the problem is massive memory is used by ansi floating lib functions.
memory resources on QG8  are quite limited.  while use floating lib ansifs.lib support and much floating computation, which very memory consuming.  QG8 memory can't hold them.
so what i suggest you is:
1. don't use floating lib and avoid floating computation in your code. this can reduce the code size.
2. if you want to use floating anyway, I suggest you choose larger memory chip instead,

"

Have a great day,
Zhang Jun
