Incorrect read data from sdram in NIOS using IORD_16Direct

Hello, i have a problem with reading data from sdram in nios using IORD_16direct. There is my code of sending data to sdram.

for(i = 0; i < 10; i++) {

int chromosome[30] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 };

int randomFirstPoint = onGetRandom(0, 29);

int randomSecondPoint = onGetRandom(0, 29);

int buff = chromosome[randomFirstPoint];

chromosome[randomFirstPoint] = chromosome[randomSecondPoint];

chromosome[randomSecondPoint] = buff;

for (j = 0; j < 30; j++) {

IOWR_16DIRECT(DRAM_BASE + count, 0, chromosome[j]);

count++;

}

}

and there is my code of redaing from sdram

for(i = 0; i < 300; i++) {

int value = IORD_16DIRECT(DRAM_BASE + i, 0);

printf("read value = %d %d\n", value, i);

}

output is

read value = 1

read value = 0 -- incorrect value instead of this would be 2

read value = 3

read value = 16128 -- incorrect value instead of this would be 4

read value = 5

read value = 0 -- incorrect value instead of this would be 6

read value = 7

read value = 16128 -- incorrect value instead of this would be 8

read value = 9

read value = 0 -- incorrect value instead of this would be 10

and so on...
