14.20 diag_flash_crc16.h File Reference

This file contains prototypes for APIs to calculate, store and validate 16-bit CCITT CRC for a given FLASH region.

Includes

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

Functions

Table 14-34. 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_INVALID_ADDRESS, CRC_INVALID_LENGTH, CRC_STORE_ERROR
Table 14-35. diag_crc_status_tDIAG_FLASH_ValidateCRC16 (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
