I am using Codewarrior 11.1 to compile the program of the S12ZVMC256 chip. In the prm file, use the CHECKSUM command to calculate the CRC of the application code. The method used is METHOD_CRC8 (Figure 1). Unfortunately, the calculated CRC result is shown as B6 (Figure 2), which is incorrect. The correct CRC should be D5. What is the reason? The project I tested is shown in the attachment.
