Where to find the SWO console output?

I'm trying to route the debug console over SWO, instead of UART. Where to find the SWO console output?

Starting with SDK example: evkbmimxrt1170_semc_cm7 (any other example using debug console should do)

using the peripherals tool - utilities - debug console

serial port type = SWO

added SDK component: ulitily.debug_console

added SDK component: component.serial_manager_swo

routed SWO to pin D6

Update code

manually copied from the SDK zip

fsl_component_serial_manager.c

fsl_component_serial_manager.h

fsl_component_serial_port_internal.h

removed

utilities/debug_console

it compiles successfully

modified code attached

Where to find the SWO console output? There are several Printf in the code, but I can’t find the output. In the unmodified code, they appear on a COM terminal.
