CAN Devices Enter Busoff State After Wakeup In S32G2

[shuangjunzhu]

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
