S32G274 M7 LLCE CAN

[zhucc]

The version of RTD is SW32G2_RTD_4.4_2.0.0_HF02，the version of RTD is S32G_LLCE_1.0.2

When using llce can, the following two types of occasional failures are encountered:

1. llce can cannot receive data; it is found that the data in can message buffers has been updated but the CAN receive descriptor has not been updated, and the RXOUT FIFO is always empty

2. llce can cannot send data, and the BLROUT FIFO is always empty

What causes this problem and what are the precautions when llce can be used？

Hi,

Are you using any NXP reference boards? 

Are you using any NXP examples? Or is this a custom application?

Which IDE version are you using?

In general, we understand that the versions you are using are legacy versions, for which we recommend updating to newer package versions. As for the behavior, we don't seem to be able to reproduce this behavior from our side. We do apologize.

We also understand that by the following words:

"occasional failures"

This does not happen always. Can you help us elaborate more on regards of the specific time which you are able to see this behavior? Is the bus fully loaded? How much nodes do you have connected to your bus?

Please, let us know.
