S32g 如何实现双核保护？

[tomhan]

hi，

请问下，S32 如何知道A核或者M核有异常，比如我想在M核知道A核是否异常了？

Hi,

At this moment the S32G support is mainly done in English, can you help us translate your question to English? We apologize.

Please, let us know.

hi，
question：How can S32g achieve dual core liveliness?

for example，if A core is abnormal，How notify the M core？
thanks

Hi,

Inside the S32G chip there is a Fault Collection and Control Unit (FCCU). The S32G2 Reference Manual mentions the following [Page 3969, S32G2 Reference Manual, Rev. 7, February 2023]:

"The FCCU provides a hardware interface to collect faults and to place the device into a safe state when a failure is detected in the device. No CPU intervention is requested for collection and control operations. FCCU offers a systematic approach to fault collection and control."

And under the Fault Map file attached to the S32G2 Reference Manual, we see the following faults:

Which are related to A core and M core being abnormal, for what we understand.

Please, let us know.
