AM335x Form Error in CAN Driver

Hello,

I am facing an issue CAN driver,

basically we are using auto baud detect feature in our driver.

there are only two nodes in our network. we support 1Mbps and 250kbps baudrate.

So when the other node changes the baudrate we have to auto detect the baudrate and change accordingly.

When other node changes from 1Mbps to 250 kbps we are getting the form error.

But instead of that one we should get the ACK error.

So just want to know whether the form error is expected in this case or whether there is some problem in initialization part.

apart from this can driver works fine.
