See logs in debug console while UART is comunicating with GPS

[Prayam]

i am working with jlink segger edu, in a custom board, it dont have swd TX, RX pins connected, only jtag pins. I Need to see if my gps conected throw uart is working or not, but i dont know how to send logs to RTT or debug console on segger while Uart is using in other job

Hi,

When the logger module use RTT as backend it uses the SWD pins. Which means that these has to be connected to use this feature. Could you provide a schematic of your custom board?

what do you mean in "these has to be connected "? i have conected SWDIO & SWDClK pins in SWD conector to SWDIO & SWDCLK pins in the MCU module respectively, wich swd pins must be conected with?

I interpreted this as you have not connected the SWD pins. I would prefer it if you could provide me with the schematics. It would clear up any misunderstandings.
