Octavio,

You need to use the PSECT method like I showed you before.  If you refer to
the Microchip programming manuals, you will see that data in the EE is
always at address 2000h (I think).  This will get the data into the chip
via the programmer.

You need to define a PSECT which puts a block of data at that address.

The note below is one I sent recently to Clyde.  It shows how to accomplish
the same _kind_ of thing - the chip type identifier into the HEX file.
Same method, different absolute address.

In order to use the automatic chip type recognition for the
Parallax/Tech-Tools burner (and I think Microchip specifies it as optional
for the .HEX file), I put together some macros you might want to add in a
future version.  They certainly make my life easier.

Keep up the good work.

Andy



// Put chip type specification into object file, for smarter burning
#define __CHIPTYPE(x)   asm("\tpsect chiptype,class=CHIPTYPE,delta=1");\
                        asm("\tglobal\tchiptype"); \
                        asm("chiptype"); \
                        asm("\tdb "___mkstr(x>>16&0xFF));\
                        asm("\tdb "___mkstr(x>>8&0xFF));\
                        asm("\tdb "___mkstr(x&0xFF))

// Table of chip type definitions for the __CHIPTYPE macro.  This enables
the program to
// provide the correct chip information to the programmer device.
// Sorry - these are the chips I'm currently using, but the types are
usually obvious
#define CT_PIC16C66     0x00660000
#define CT_PIC16C67     0x00670000
#define CT_PIC16C76     0x00760000
#define CT_PIC16C77     0x00770000
#define CT_PIC16F876    0x08760000
#define CT_PIC16F877    0x08760000


This goes into the main C file

__CHIPTYPE(CT_PIC16F876);
