Configuration for flash is as follows:
SSD_CONFIG FLSHM_ssdConfig = {
C55_REG_BASE, /* C55 control register base */
MAIN_ARRAY_BASE, /* base of main array */
{ 0, 0, 0 }, /* blocks info of low address space */
{ 0, 0, 0 }, /* blocks info of mid address space */
{ 0, 0, 0 }, /* blocks info of high address space */
0, /* number of blocks in 256K address space */
UTEST_ARRAY_BASE, /* base of UTEST array */
TRUE, /* interface flag indicate main or alternate interface */
0x80,/* programmable size */
FALSE /* debug mode selection */
};
Below steps to get flash block erased-
#define LOWBLOCKSELECT 0x00000200U (0x00FF0000)
#define MIDBLOCKSELECT 0x00000000U
#define HIGHBLOCKSELECT 0x00000000U
/* Unlock the requested block for Erase operation */
nLargeBlockSelect.firstLargeBlockSelect = 0;
nLargeBlockSelect.secondLargeBlockSelect = 0;
SetLock(&FLSHM_ssdConfig, C55_BLOCK_LOW, UNLOCK_ALL_BLOCKS);
/* Erase the requested block */
Return_Val = FlashErase(&FLSHM_ssdConfig, C55_ERASE_MAIN, LOWBLOCKSELECT,
MIDBLOCKSELECT, HIGHBLOCKSELECT, nLargeBlockSelect);
if(Return_Val == C55_OK)
{
while(C55_INPROGRESS == FlashCheckStatus(&FLSHM_ssdConfig, C55_MODE_OP_ERASE, &opResult, &FLSHM_eraseCtxData));
/* Erase is successful */
}
else
{
/* Erase failed */
}
