Banked memory quesion (Z80 using IAR)

Hi All,

I've just inherited a project that was written for a Z80 platform usin IAR 2.01G compiler.

It?s using banked memory to cross the 64k boundary.

I've a problem addressing variables across pages.

Consider the following example:

///////////// file: moduleA.c //////////////////////////////// //Module A:

#pragma memory=dataseg(MOD_A_DATA) MOD_A_STRUC mod_a_struc;

#pragma memory=constseg(MOD_A_CONST) const char teststr[]="test string"; #pragma memory=default

#pragma codeseg(MOD_A_CODE) Void MOD_A_SET(MOD_A_STRUC * m, int x, int y) { m->member1 = x; m->member2 = y; }

int MOD_A_GET1(MOD_A_STRUC * m, int x, int y) { return m->member1; }

int MOD_A_GET2(MOD_A_STRUC * m, int x, int y) { return m->member2; } /////////////// end module A ////////////////////////////////

Now the main module:

///////////// file: main.c //////////////////////////////// //Module main:

#pragma memory=dataseg(MOD_A_DATA) extern MOD_A_STRUC mod_a_struc;

#pragma memory=constseg(MOD_A_CONST) extern const char teststr[]; #pragma memory=default void main(void) { int I, j; MOD_A_SET(mod_a_struc, 0x12, 0x34); i = MOD_A_GET1(mod_a_struc); j = MOD_A_GET2(mod_a_struc);

printf("%s : %i %i\n\r", teststr, i, j ); }

///////////// end module main ////////////////////////////////

The calls to the set & get function don't seem to address the righ mod_a_struc in memory.

What am I doing wrong?!!!

Thanks & best regards,
