Tool/software:
Dear Supportteam,
I'm actually trying to activate the crc checksum algorithm over my text file section of linker file.
What is clear for me, is how to activate and to configure the linker command file.
for example:
.text : palign(8) {} > FLASH | FLASH2, crc_table(crc_table_for_text,algorithm= CRC32_PRIME)
What I'm unsure is how to implement it correctly on MSPM0G3507 by using the hardware crc component.
As far as I understand, I have first to initialize the crc component:
void BSL_CRC_Init(void)
{
/* Reset and enable power to CRC */
DL_CRC_reset(BSL_CRC);
DL_CRC_enablePower(BSL_CRC);
while (DL_CRC_isPowerEnabled(BSL_CRC) != true) {
}
/* Initialize the CRC module */
DL_CRC_init(BSL_CRC, DL_CRC_32_POLYNOMIAL, DL_CRC_BIT_REVERSED,
DL_CRC_INPUT_ENDIANESS_LITTLE_ENDIAN, DL_CRC_OUTPUT_BYTESWAP_DISABLED);
}
But then the questions begin.1) Is CRC32_PRIME the same as DL_CRC_32_POLYNOMIAL
2) How to call the calculation correct, is this the correct method which is indirect given in BSL example?
uint32_t BSL_CI_calculateCRC(uint8_t *data, uint32_t dataSize)
{
uint32_t bufferIndex = (uint32_t) 0;
/* Set the Seed value to reset the calculation */
DL_CRC_setSeed32(BSL_CRC, BSL_CRC_SEED);
/* Feed the data to CRC module */
for (bufferIndex = (uint32_t) 0; bufferIndex < dataSize; bufferIndex++) {
DL_CRC_feedData8(BSL_CRC, data[bufferIndex]);
}
/* Return the 32 bit result */
return (DL_CRC_getResult32(BSL_CRC));
}
Or does TI provide any example for this job?
How to get addresses and lengths, I found in another post:

This solved this question, but not how to implement the correct hardware crc usage.
