C++ (Cpp) Chip_IAP_EraseSector Examples

Example #1

File: nv_storage.c Project: i7sid/SkyNet-Dongle

bool skynet_nv_write(NV_DATA_T* new_data) {
	__disable_irq();
	uint8_t r = 0;

	// prepare
	r += Chip_IAP_PreSectorForReadWrite(SECTOR_NUM, SECTOR_NUM);

	// erase
	r += Chip_IAP_EraseSector(SECTOR_NUM, SECTOR_NUM);

	// prepare again
	r += Chip_IAP_PreSectorForReadWrite(SECTOR_NUM, SECTOR_NUM);

	// write
	r += Chip_IAP_CopyRamToFlash(SECTOR_STARTADDR, (uint32_t *)new_data, sizeof(NV_DATA_T));

	// read again, just for sure
	skynet_nv_read(&read);

	__enable_irq();
	return (r == 0);
}

Example #2

File: lpc43_flash.c Project: ernesto-g/micropython

void flash_erase(uint32_t f_dst, const uint32_t *src, uint32_t n_words) {
	uint8_t e;

	if (n_words == 0) {
		return;
	}
	__disable_irq();

    // erase the sector(s)
	uint32_t Start = flash_get_sector_info(f_dst, NULL, NULL);
	uint32_t End = flash_get_sector_info(f_dst + 4 * n_words - 1, NULL, NULL);

    e = Chip_IAP_PreSectorForReadWrite(Start, End, BANK);
	F_ASSERT(e != IAP_CMD_SUCCESS, "Prepare for erase FAIL");
