LAUNCHXL2-570LC43: EMIF SDRAM acsess TMS570lc43

I have a structure.

struct TelemPackStruct
{
                 uint32_t tmMarker;
                 float32_t    wx ;
                 float32_t    wy ;
                 float32_t    wz ;
                 float32_t    m1 ;
                 float32_t    m2 ;
                 float32_t    m3 ;
                 float32_t    q0 ;
                 float32_t    q1 ;
                 float32_t    q2 ;
                 float32_t    q3 ;
     struct BinData{
                 uint32_t seconds            :32;
                 uint32_t indication         :8;
                 uint32_t mode               :8;
                 uint32_t modeArea            :8;
     }binDataTM;

};

I need to save this type of structure every second with different values in the emif.

I  enabled the emif in the Halcogen (sdram, async1,2,3, pinmux, driver).

I modified the linker file :

MEMORY
{
    VECTORS (X)  : origin=0x00000000 length=0x00000020
    KERNEL  (RX) : origin=0x00000020 length=0x00008000 
    FLASH0  (RX) : origin=0x00008020 length=0x001F7FE0
    FLASH1  (RX) : origin=0x00200000 length=0x00200000
    STACKS  (RW) : origin=0x08000000 length=0x00000800
    KRAM    (RW) : origin=0x08000800 length=0x00000800
    RAM     (RW) : origin=(0x08000800+0x00000800) length=(0x0007F800 - 0x00000800)

/* USER CODE BEGIN (2) */
 	SDRAM   (RXW) : origin=0x80000000 length=0x007FFFE0
/* USER CODE END */
}

and

SECTIONS
{
    .intvecs : {} > VECTORS
    /* FreeRTOS Kernel in protected region of Flash */
    .kernelTEXT  align(32) : {} > KERNEL
    .cinit       align(32) : {} > KERNEL
    .pinit       align(32) : {} > KERNEL
    /* Rest of code to user mode flash region */
    .text        align(32) : {} > FLASH0 | FLASH1
    .const       align(32) : {} > FLASH0 | FLASH1
    /* FreeRTOS Kernel data in protected region of RAM */
    .kernelBSS    : {} > KRAM
    .kernelHEAP   : {} > RAM
    .bss          : {} > RAM
    .data         : {} > RAM

/* USER CODE BEGIN (4) */
    .telem  : {} > SDRAM
/* USER CODE END */
}

I defined an array of structs

#define NUM_OF_PACKS   1024

struct  TelemPackStruct  telemetry [NUM_OF_PACKS] __attribute__((section(".telem")));

The problem i found is the following.

__attribute__((section(".telem"))) volatile  struct  TelemPackStruct  telemetry [NUM_OF_PACKS];

void foo(){
    volatile struct TelemPackStruct tmToRead;
    //filling tmToRead
    telemetry[0]=tmToRead;
 
    //telemetry[0].q1=tmToRead.q1; does the same problem

}

When i try to write telemetry[0] that is stored in the EMIF, it writes only one variable (not single in the structure) and writes it on the WHOLE SDRAM (include ).
