No output from S12ZVML31 serial port

[mine233]

I transplanted the S12ZVML128 program to S12ZVML31, and the program is running normally. However, freemater can only connect the motor through mutilink, not through serial port. There is no output from the serial port tested separately. The program also initializes SCI. What is the reason for this.

Hello @mine233,

Do you use the correct SCI pins of the MCU?

Do you have an NXP EVB or your own board?

Can you share the code?

Thank you,

BR, Daniel
