CRC k60 example

barbercolman — Tue, 03 Jul 2012 02:00:56 GMT

I have the k60 quick start demo running and wanted to add a crc to the communications. I added

crc_error=CRC_Config(0x1021, 0, 0, 0, 0);

crc = CRC_Cal_16(seed, mSendBuffer, BSP_DSPI_TX_BUFFER_SIZE);

and was able to link and compile. However program execution never returns from CFC_Config and throws an unhandled execption. Any help?

I don't believe that CRC_Config function enables the clock for the CRC module. For K60, precede with:

SIM_SCGC6 |= SIM_SCGC6_CRC_MASK;
