How to Calculate FlexRay Header CRC

Hi everyone,


We are using MC9S12XF512 to build a FlexRay application. However, we cannot figure out how the Header CRC configured for each message buffer is calculated.


The official FlexRay does give an algorighm, but it looks like that the actual implementation in MC9S12XF512 is different. Because we tried to use that algorithm to calculate the Header CRC, but the result is different from the value given in the sample applications.


Any advice?


Thanks a lot.
