CAN initialization failed

Hello, TI engineers:

     Our company is using DSP TMS320F28377S, a piece of DSP occasionally failed to initialize CAN, and the rest of the functions are normal. After the CAN is configured in the current program, there is a delay of 10ms, and the fault needs to be delayed for 20ms before the fault disappears.Does the CAN initialization time of this IC exceed 10ms? If it exceeds 10ms, is there a suggested delay time?

 Best wishes

Susan Yang:

请问出现CAN不能正常初始化的概率大吗?是您自制板子?另外在出现问题的芯片上运行TI CAN例程是否可以正常初始化?

您在为28377板加电时,请检查CAN收发器是否也已加电。

选择的CAN时钟源是什么?上电/复位后,此时钟源是否稳定?

此外,请您参考文档:
