Hello @songhongliang 

I hope you are doing well.

1)Where to change the sample point settings?
One can change the settings of the CAN device properties.
ip link set DEVICE type can

"bitrate 125000 sample-point 0.875"
by this argument, one can set the bitrate and optionally one can set the sample-point

after Please verify the values by
ip -details -statistics link show can0

For more details please refer to the can.rst file in the Linux source code.
<source_code>/Documentation/networking/can.rst

2)Is the default adoption point of the flexcan driver 75%?
Can you please kindly elaborate on this term & share more detail on it?

Thanks & Regards.
