MBs number of FlexCan in Processor Expert , Number of buffers of Can_PAL in Mex

[samcs]

i wonder if the Configuration parameter: Number of buffers of Can_PAL in S32DS 3.4 platform, is the same meaning of the configuration parameter: MBs number of FlexCan in Processor Expert ?

Hi@samcs

Checked the driver code, the meaning of these two parameters should be the same.

/* Configure features implemented by PAL */
 flexcanConfig.max_num_mb = config->maxBuffNum;

br!

In fact, i found an issue about the cycle time of Tx Messages are not stable, ex: 40ms cycle time, 

it varied from 39XXX to 44xxxx.

I changed the project from S32DS for Arm 2.0 , PE, flexcan compoent to new S32DS34 , Mex, CAN_PAL,

the project on S32DS for Arm 2.0 works well, 40 ms cycle time, 

it showed 39xxx to 40xxxx.

Please help to give some ideas, thanks

Thanks,

While, Number of buffers in CAN_PAL_Component, be limited to 7, why in PE, the MBs number can be set to 32?

Hi@samcs

1. The size of the payload will affect the number of Buffers

2. Can you provide your demo code? I may need to follow your method to reproduce the problem.

BR!
