crc_check()

FctERR crc_check	(	const uint32_t	crc_ref,
		const eCRCFeedSize	feed_size,
		const uint32_t	start_addr,
		const uint32_t	size )

CRC check.

Parameters

[in]	crc_ref	- CRC to check against
[in]	feed_size	- CRC peripheral feed size
[in]	start_addr	- Start address of block to compute CRC
[in]	size	- Size of block to compute CRC (in Bytes)

Return values

ERROR_OK	- CRC consistent
ERROR_CRC	- CRC inconsistent
ERROR_VALUE	- feed_size is not a value of enum eCRCFeedSize
ERROR_COMMON	- size is not int division with feed_size
