I am using the imx6ull .I want to set the low CAN bitrate ,such as 6K or 10K. But I can't set it. If I set the bitrate which above the 20K, it is right.
Hi cx
one can try to select suitable reference clock:

Hi. I have a look at the flexcan clk source change on imx6ULLRM. But the FLEXCAN_CTRLX don't have the register on imx6ullRM. I also have a look at the imx25RM. The bit13 of the FLEXCAN_CTRLX is the clk source change bit. So I don't know imx6ull can or not select the clk source.
