CAN Devices Enter Busoff State After Wakeup In S32G2

Hi Experts,
Customer encounter an issue. While the S32G M7 core is wakeup from sleep state, it will execute the same process as the cold-start for power-up.

The LLCE can2can routing is enabled. Before sleep, the CAN network is working well.

Usually, the CAN devices will report BUSOFF error once the M7 core re-enable the BCAN controller in wakeup (same as power-on) process.

Please help to review whether the initiation sequence of LLCE MCAL driver rightly cover this kind of corner case.

Thanks,

Jeff
