EEPROM emulation using FLASH - How to initialize variables

Hi Lori, (Sorry for the big picture above, I tried to insert it between the lines but was unsuccessful...)

Ok, so this is what I tried to do:

Defined a section in the cmd file:

PAGE 1 :

....

D_FLASHA    : origin = 0x3F6000, length = 0x001F7F

SECTIONS
{

.....

my_sec              : > D_FLASHA     PAGE = 1

}

Define an .asm file with the values:

    .sect "my_sec"

      .int    -1587        
      .uword  5342        
      .float  3.2567 

Defined a .c file with the struct, with DATA_SECTION pragma:

#pragma DATA_SECTION(struct1,"my_sec")

typedef struct my_struct
{
    int16    a;
    Uint16    c;
    float32    b;
}my_struct;

my_struct    struct1;

So the Flash was initialized (I don't know why all the trailing zeros..maybe alignment issue...).

And struct1 is of course not initialized correctly.

But it's initialized with zeros... So something is happening there...

Can you please advise what is wrong, and if this is the correct method to implement what I want ?

Thanks a lot

The linker has allocated struct1 followed by your mysec data.  In order for them to overlap you need to use a UNION in the linker command file.
