Function Documentation

CHK_crc32()

uint32_t CHK_crc32	(	uint8_t *	data,
		uint32_t	len
	)

CHK_crc32 provides crc32 algorithm.

This function provides crc32 checksum functionality with hardware support. It has been modified to match the common implementations used in zlib/WinZip/... RCC_CRC_CLK needs to be enabled.

Returns

(type: uint32_t)

CHK_Flashchecksum()

STD_RETURN_TYPE_e CHK_Flashchecksum

(

const VER_ValidStruct_s *

valid_struct

)

CHK_Flashchecksum provides validation for the currently used firmware.

This function gets called during startup and validates the currently used firmware by doing a checksum over pre-defined memory areas and compares result with a pre-calculated checksum stored in the flashheader

Returns

(type: uint8_t)
