diag_flash_crc32.h File Reference

This file contains prototypes for APIs to calculate, store and validate 32-bit CRC for a given FLASH region.

Includes

  1. 1.diag_memory_types.h
  2. 2.../../../diag_common/config/diag_config.h

Functions

Table 1. diag_crc_status_tDIAG_FLASH_CalculateStoreCRC32 (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 2. diag_crc_status_tDIAG_FLASH_ValidateCRC32 (uint32_t startAddress, uint32_t length, uint32_t refAddress).
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] refAddress

uint32_t

- the FLASH address where reference CRC is available

Returns
diag_crc_status_t CRC_OK, CRC_ERROR, CRC_INVALID_ADDRESS, CRC_INVALID_LENGTH, CRC_STORE_ERROR
