HI~all

 

Did you have any idea with setting sim module baud rate on imx6ul?

In IMX6UL.RM ch45, we set SIM Control Register bit 6~8 to determine baud rate.

My question is :

1. If i want to set flexible divisor, i need to set sim baud_sel  register to "111". And set the SIM Divisor Register.

    But i set any value to this register. It fail on data transmit. So, what value i need to set ?

2. If i set the two register above, i need to set the sample12 register at the same time?

     If i enable this register, it means what value divide by 12 ? 

 

3. Could you support me a way to set divisor with these register ?? 

 

Thanks~
