hi carlos.
and also what is block-0 and block-1 flash program.each are 512 kb .so this place i want to change anything?
and flash demo example swap is there is anything i want to change. i attached my flash write,read,erase code.
void internal_flash_write()
{
uint32_t ret; /* Return code from each SSD function */
uint32_t destination; /* Address of the target location */

uint32_t end;

uint16_t number; /* Number of longword or phrase to be program or verify*/
uint32_t *p_data;
uint32_t margin_read_level; /* 0=normal, 1=user - margin read for reading 1's */
