Hi NXP Experts,
There was an abnormality in the use of the LLCE can function of the S32G399A in our project. Occasionally, there was an issue with the reception of a certain CAN message reported by the ECU, while the transmission was normal. After debugging, it was found that the can interrupt could be triggered normally, but the u32Word0 read from Can_SharedMemory changed from 0x18008 to 0x1800f, which was an abnormal value. The calculated u32MbMessageId was 0.This led to message loss.
The RxMbDescIdx had a value and was changing, and word1 sometimes was 0 but was also changing. This situation occurred sporadically, and the affected CAN line was also random.
Please help analyze this situation,The debugging screenshots are provided below. How should I proceed with the next debugging steps, or what solutions are there?
The LLCE version is: 1.0.10
.
Yes, we use our own boards and software. We employ LLCE in the M core and have integrated the MICROSAR com protocol stack of vector.
