S32K144_CRC-16-IBM

kwakd_y — Tue, 10 Jul 2018 02:05:22 GMT

I would like to modify the CRC example code provided by the S32 DS.

Example code is "CCITT 16 bits standard" but I have to use "CRC-16-IBM"

Which part should I modify?

Can you provide a fix code?

The example code is "crc_checksum_s32k144" in the S32 design studio.

- .CRC-16-CCITT (x16 + x12 + x5 + 1)

- .CRC-16-IBM (x16 + x15 + x2 + 1)

In example code

/*!< CRC Polynomial, MSBit first.<br/>

* Example polynomial: 0x1021U = 1_0000_0010_0001 = x^12+x^5+1 */

Hi,

you can modify processor expert CRC module (double click to crc1:crc in components) to met your needs:
