S32K3x4-Q172 Serial communication

[Canberk]

When I tried to open freemaster I have got could not open the communication port error and I couldn't see my board as port as well in other serial port programs. How can I solve this problem

Thanks

Hi @Canberk,

I'm not sure I understood your issue.

1. Does you PC correctly identify the COM port corresponding to your S32K3 board in device manager when you connect your board to the PC ?
2. Is the UART interface used by any other application beside FreeMASTER ?
3. What type of application are you running on the board ? Is it an example provided by NXP or your custom application ?
