Part Number: TMS570LC4357

Tool/software:

I'm facing a problem in LIN communication. When I send the header information, it is going to Physical bus error. So what could be the problem here?

Hi Deepak,

Need more information:

Which board you are using for your test Launchpad/HDK/custom board?

Which LIN instance you are using LIN1 or LIN2?

How are you testing the LIN? Did you connect any other board at other end?

Can you check below thread once, this thread explained a potential issue with LIN1 in launchpad or HDK board:

Thanks & regards,

Thank you for your response jagadish. I'm using Eval board with LIN1 instance connecting it to FTDI4232 IC. Now let me check with the thread which you have shared.
