Hi, Dear support

I face an issue with Sphaero LIN on spc574s60. We are in slave mode, using LINFLEX_0.

Look the INESR value, in this state I can have LIN error interrupt, synch error and frame error. The team investigate for a week and have no idea why we are in this state. Clock looks good, Lin initialization looks good. Rx looks like working, it receive something but can not  understand the header correctly, please give us some hint what we can check.

The exact µC we are using is:

AA-ENG-0

SPC574S60L5

VQ40419217

226XN VQ

MLT 11 417

Is there a list of Known issue regarding the chip for linflex.

Hello Cindy ,

We have no known bug but it is important to respect this relationship.

Separate clock for baud rate calculation

(The relationship LIN_CLK > PBRIDGEx_CLK > 1/3*LIN_CLK should be maintained.)
