crc_calculate

This example is used to calculate CRC 16/32.

Use CRC16

// at main.c
#define CONFIG_USE_CRC16            1

Use CRC32

// at main.c
#define CONFIG_USE_CRC16            0

Log

Use serial port with baudrate 115200 8bit, no parity check.
User can receive log infomation from PA00(Uart TXD) of DUT.

    crc= 0x00006679
    CRC verify OK~~

  two-part accumulation:
    crc= 0x00004546 (addr: 0x200001C8 ~ 0x20000207)
    crc= 0x00006679 (accumulate to 0x20000247)
    CRC verify OK~~
