3.1.8.3.2 DIAG_FLASH_CalculateStoreCRC32()

diag_crc_status_t DIAG_FLASH_CalculateStoreCRC32 (uint16_t startAddress, uint16_t length, uint16_t storeAddress)

The CRC Flash test implements the periodic modified checksum (H.2.19.3.1) defined by the IEC 60730 standard. This API calculates 32-bit CRC for a given FLASH memory region and stores the same at FLASH address indicated by storeAddress argument.

Parameters:
in startAddress

- starting address of FLASH memory region to be considered for CRC

in length

- number of bytes from startAddress to be considered for CRC

in storeAddress

- the FLASH address where calculated CRC will be stored

Returns:

CRC_OK, CRC_ERROR, CRC_INVALID_ADDRESS, CRC_INVALID_LENGTH
