Hello,
I am working on the bootloader, trying to flash only 256 bytes. So, before flashing, erasing the block 0xFF0000. There is already some data in this block. But erase is not happenin, even if FlashErase() returns 0 and FlashCheckStatus() also gives opResult=0. Also when I check memory, it still shows the same data and not erased.
Following below steps to get flash block erased-
#define LOWBLOCKSELECT 0x00000100U
#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);
irqIsrDisable();
/* 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 in progress */
}
else
{
/* Erase failed */
}
irqIsrEnable();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 */
256U,/* programmable size */
FALSE /* debug mode selection */
};
What could be the issue here?
