Hi Support team,
I have found some issue while re-writing at last sector i.e.(0x1FC00 - 0x1FFFF) in MSPM03507 mcu.
I am trying to write at location 0x0001FF00. Initially When i write at this location its working fine. But when i try to erase that area and re-write something. It doing nothing. I am using example code only and modified as per my requirement.
/* Address in main memory to write to */
#define MAIN_BASE_ADDRESS (0x0001FF00)
/* 32-bit data to write to flash */
uint32_t gData32 = 0x33333333;
/* 32-bit data to write to flash */
uint32_t gData32_1 = 0x44444444;
int main(void)
{
SYSCFG_DL_init();
/* Unprotect sector in main memory with ECC generated by hardware */
DL_FlashCTL_unprotectSector(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_REGION_SELECT_MAIN);
/* Erase sector in main memory */
gCmdStatus = DL_FlashCTL_eraseMemoryFromRAM(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_COMMAND_SIZE_SECTOR);
if (gCmdStatus == DL_FLASHCTL_COMMAND_STATUS_FAILED) {
/* If command was not successful, set error flag */
gErrorType = ERROR_ERASE;
}
if (gErrorType == NO_ERROR) {
/* 32-bit write to flash in main memory with ECC generated by hardware */
DL_FlashCTL_unprotectSector(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_REGION_SELECT_MAIN);
gCmdStatus = DL_FlashCTL_programMemoryFromRAM32WithECCGenerated(
FLASHCTL, (MAIN_BASE_ADDRESS), &gData32_1);
if (gCmdStatus == DL_FLASHCTL_COMMAND_STATUS_FAILED) {
/* If command was not successful, set error flag */
gErrorType = ERROR_32BIT_W;
}
}
/* Unprotect sector in main memory with ECC generated by hardware */
DL_FlashCTL_unprotectSector(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_REGION_SELECT_MAIN);
/* Erase sector in main memory */
gCmdStatus = DL_FlashCTL_eraseMemoryFromRAM(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_COMMAND_SIZE_SECTOR);
if (gCmdStatus == DL_FLASHCTL_COMMAND_STATUS_FAILED) {
/* If command was not successful, set error flag */
gErrorType = ERROR_ERASE;
}
if (gErrorType == NO_ERROR) {
/* 32-bit write to flash in main memory with ECC generated by hardware */
DL_FlashCTL_unprotectSector(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_REGION_SELECT_MAIN);
gCmdStatus = DL_FlashCTL_programMemoryFromRAM32WithECCGenerated(

if (gCmdStatus == DL_FLASHCTL_COMMAND_STATUS_FAILED) {
/* If command was not successful, set error flag */
gErrorType = ERROR_32BIT_W;
}
}
/* After successful completion, toggle LED and USER_TEST pin */
if (gErrorType == NO_ERROR) {
/*
