I was under the assumption that all const declarations were assigned to the ROM sections. But when I specify the constants as

shown below, these constants were assigned to data sections. How can I assign the following to ROM sections?

const S_TBL *sp_tbl[]={

p00, /* pointer to structure */

p01, /* pointer to structure */

p02, /* pointer to structure */

};

To assign the above constants to the ROM section, please specify sp_tbl in the following way:

S_TBL *const sp_tbl[]={

p00, /* pointer to structure */

p01, /* pointer to structure */

p02, /* pointer to structure */

};

You need to assign p00, p01, and p02 as well as sp_tbl to the ROM section:

const S_TBL *const sp_tbl[]={

p00, /* pointer to structure */

p01, /* pointer to structure */

p02, /* pointer to structure */

};

[Reference]

When using a const-declaration to a pointer, what is assigned to the ROM will differ depending on the position of the const.

In the following example,

const int *i={a,b,c};

"a, b, c" will be assigned to the ROM.

But, in the following example,

int * const i={a,b,c};

"i" will be assigned to the ROM.
