Thingy53 not displaying output from RTT

[Aman711]

Hi Team,

I have connected my THingy53 board with nRF5340_DK board for flashing and debugging but i have not seen any output from the device on respective ports and also RTT consol.

I have tried Hello world code and also tried several solutions but could not able to get the output. (I am able to get output from nRF5340_DK module on Port11)

Setup: VS Code with Nordic extension

The debug cable between DK and target board only connects the SWD signal for RTT, and RTT is not used in the examples by default.

The VCOM ports are only connected to the MCU on the DK.

You can enable RTT console in prj.conf or via Kconfig.

Thanks for response 

I have set like ton of config in prj.conf file as below, but did not get any output.

CONFIG_RTT_CONSOLE=y

CONFIG_UART_CONSOLE=y

CONFIG_STDOUT_CONSOLE=y

CONFIG_LOG=y

CONFIG_USE_SEGGER_RTT=y

CONFIG_LOG_BACKEND_RTT=y

CONFIG_LOG_BACKEND_UART=y

CONFIG_SEGGER_RTT_BUFFER_SIZE_DOWN=64

CONFIG_MAIN_STACK_SIZE=8192

CONFIG_SEGGER_RTT_BUFFER_SIZE_UP=4096

CONFIG_LOG_BUFFER_SIZE=4096

Please suggest if you find anything or else suggest me some documentation or example which I could follow.

Thanks in advance.

Hello, in order to use RTT you will need to disable the UART backend. Please see nRF Connect SDK documentation on Logging backends and How to use RTT.

Kind regards,
