Hi Sung,

Sample mode can be updated by changing the CanControllerSyncJumpWidth parameter.

Hi Maheswar.
Can you explain in more detail?
How does it work to adjust sampling count with SJW?

In my case, what is the sampling count? (Not time width , it's question about sampling count adjustment)
The CanControllerBaudrateConfig parameter below is my current configuration.

CanControllerBaudRate = 500
CanControllerPropSeg = 47
CanControllerSeg1 = 16
CanControllerSeg2 = 16
CanControllerSyncJumpWidth = 16
