Error with FreescaleIAP code with K22F

Hi again!

I have a K22F platform. I found a problem with the example code of the FreescaleIAP library, i've just done an easier code from this:

--------------

1. include "mbed.h"
2. include "FreescaleIAP.h"

int main() { int sizeflash = flash_size(); printf(" Flash Size: %d\r\n",sizeflash);

int sizesector = SECTOR_SIZE; printf("Sector Size: %d\r\n",sizesector);

int address = flash_size() - SECTOR_SIZE; int *data = (int*)address; printf("Address: %d\r\n",address); printf(" \r\n");

printf("Starting\r\n"); erase_sector(address);

int numbers[2] = {5,6}; program_flash(address, (char*)&numbers, 8);

printf("Resulting flash: \r\n"); for (int i = 0; i<2; i++) printf("%d\r\n", data[i]);

printf("Done\r\n\n");

while (true) { } }

--------------

While i'm printing, "data[i]" returns me only "-1" values, whatever are the variables in the array.

I tried to change the bytes i program (4, 8 and 16) but it returns me always "-1".

Which could be the problem?

Thank you!!
