diag_flash_crc16_lookup.c File Reference

This file contains APIs to test FLASH using CRC16 CCITT Look-up Table algorithm.

Includes

Table 1. voidDIAG_FLASH_CalculateCRC16 (uint32_t startAddress, uint32_t length, uint16_t *crcSeed).

Parameters

[in] startAddress	uint32_t - starting address of FLASH memory region to be considered for CRC
[in] length	uint32_t - number of bytes from startAddress to be considered for CRC
[in, out] crcSeed	uint16_t * - pointer to initial and final CRC

Returns

void

None

Table 2. diag_crc_status_tDIAG_FLASH_CalculateStoreCRC16 (uint32_t startAddress, uint32_t length, uint32_t storeAddress).

Parameters

[in] startAddress	uint32_t - starting address of FLASH memory region to be considered for CRC
[in] length	uint32_t - number of bytes from startAddress to be considered for CRC
[in] storeAddress	uint32_t - the FLASH address where calculated CRC will be stored

Returns

diag_crc_status_t

CRC_OK, CRC_ERROR, CRC_INVALID_ADDRESS, CRC_INVALID_LENGTH, CRC_STORE_ERROR

Table 3. diag_crc_status_tDIAG_FLASH_ValidateCRC16 (uint32_t startAddress, uint32_t length, uint32_t refAddress).
