question:set the dbitrate 5000000,but show 4857142 ?

There may be several reasons:
1.the Clock is wrong,maybe pllaon, not pll_c;
2.the tcan332G baud rate limit ,could not set 5000000;
3.other reasons

please help me,thank you!

Hello again,

Thank you for translating the last part of your post.

Unfortunately this does not make it much clearer.

I assume based on the Tag that you are working with DriveOS. But which device are you trying to connect?
If you can tell us that thatn we can point you to the correct DriveOS sub-category here on the forums.

And for future reference please do not open new topics but rather reply on just one of them. I scheduled the other one to close, so please stay in this topic for further discussion.

Thanks!
