2.43.3 FCR_CRCCalculate Function

C 

bool FCR_CRCCalculate (uint32_t startAddress, size_t length, uint32_t crcSeed, uint32_t * crc)

Summary

Computes the CRC for a specified memory region

Description

Configures CRC registers, performs the calculation, and retrieves the resulting CRC value.

Precondition

None

Parameters

ParamDescription
startAddressThe starting memory address of the data block for CRC calculation.
lengthThe length of the data block to be processed
crcSeedThe initial seed value for the CRC calculation.
crcPointer to store the resulting CRC value after computation.

Returns

Always returns true.

Example 

    uint32_t crcSeed = 0xFFFFFFFF;      // Initial CRC seed value
    uint32_t calculatedCrc = 0;         // Variable to store the result
    uint32_t *crc = &calculatedCrc;     // Pointer to the CRC result

    bool result = FCR_CRCCalculate(0xC008000U, 128, crcSeed, crc);
