Hello Team,

 

We are developing a custom board based on the STM32N657 MCU. During pin assignment in the CubeMX tool, PB3 is shown with the JTDO_SWO function. However, the datasheet indicates that the SWO functionality is associated with PB5.

Could you please confirm which pin actually supports the SWO function?

If you click on PB5 will you see SWO there?
