Crc check
void	restore_crc_check_failure_pin (void)
	Restore crc check failure pin to default state.

void	init_crc_check_status (property_store_t *propertyStore)
	Initialize crc check status property based on BCA related fields.

bool	is_application_crc_check_pass (void)
	Compare the CRC on a range of flash(specified in BCA) against a precomputed CRC value(stored in the BCA).

uint32_t	calculate_application_crc32 (crc_checksum_header_t *header, uint32_t crcHeaderStart)
	Calculate CRC checksum according to specified checksum header. More...

Data Structure Documentation

struct crc_checksum_header_t

CRC Checksum Header.

Data Fields
uint32_t	crcByteCount	[08:0b]
uint32_t	crcExpectedValue	[0c:0f]
uint32_t	crcStartAddress	[04:07]
uint32_t	tag	[00:03] Tag value used to validate the bootloader configuration data. Must be set to 'kcfg'.

Application crc check status codes.

Enumerator
kStatus_AppCrcCheckPassed	Crc check is valid and passed.
kStatus_AppCrcCheckFailed	Crc check is valid but failed.
kStatus_AppCrcCheckInactive	Crc check is inactive, Needs to be verified.
kStatus_AppCrcCheckInvalid	Crc check is invalid, As the BCA is invalid or crc parameters are unset (all 0xff bytes).
kStatus_AppCrcCheckOutOfRange	Crc check is valid but addresses are out of range.

uint32_t calculate_application_crc32	(	crc_checksum_header_t *	header,
		uint32_t	crcHeaderStart
	)

Calculate CRC checksum according to specified checksum header.
