There are logged reset sources.</P> <P>Also you can check FCCU module NCFS flags for issue root cause (remember to set 0xA to the Control (FCCU_CTRL) OPS field).</P> <P>If possible share them with me so I can see where is the issue.</P> <P>&nbsp;</P> <P>best regards,</P> <P>Peter</P> Fri, 04 Dec 2020 07:29:34 GMT https://community.nxp.com/t5/MPC5xxx/CAN-question/m-p/1193761#M16785 petervlna 2020-12-04T07:29:34Z
