Hi everybody.
In the .cmd linker file i have define a memory area for EEPROM emulation named EEPROM_SECT
MEMORY
{
PAGE 0: /* Program Memory */
/* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE1 for data allocation */
RAMM1 : origin = 0x000400, length = 0x000400 /* on-chip RAM block M1 */

dataRAM : origin = 0x008300, length = 0x000D00 /* Ram da usare come Ram */
}
I created an sector denominate EepromFlashSector that i want put in EEPROM_SECT

IIn my code allocate a variabile on EepromFlashSector
#pragma DATA_SECTION(eepromPages, "EepromFlashSector"); EEPROMPAGE eepromPages[EEPROM_NUM_PAGES];
My problem is that this variabile don't start at origin address of EEPROM_SECT but 64 byte later so i can't use the entire space that i have reserved for eeprom, someone can tell me what wrong so i can fill the entire eeprom space.
In the .map file under here you can see where the linker allocate the variabile
