For RT1064, I would like to use the SWO trace function, located on pin GPIO_AD_B0_10. Does this require any external component such as pull-up or pull-down resistor? I do not see this information anywhere in RT1064 documentation.
The reason I ask is because on RT1064 EVK, GPIO_AD_B0_10 is used as an interrupt signal for Ethernet (net "ENET_INT") which has a 1k pull-up resistor on it.

Hello Jason,
Hope you are doing well.
You may refer to this document for debug considerations. For the SWO you must use a pull-up for better performance.
