Hi,
I built the lighting-app(Link) and run on nrf52840 DK.
Then, I tried to replace the serial shell console with RTT shell console.
I append the configs below to the prj.conf to enable RTT shell:
#enable rtt shell
CONFIG_UART_CONSOLE=n
CONFIG_SHELL_BACKEND_SERIAL=n
CONFIG_RTT_CONSOLE=y
CONFIG_RTT_TX_RETRY_CNT=2
CONFIG_RTT_TX_RETRY_DELAY_MS=2
CONFIG_SHELL_BACKEND_RTT=y
CONFIG_SHELL_PROMPT_RTT="rtt:~$ "
CONFIG_SHELL_RTT_RX_POLL_PERIOD=10
CONFIG_SHELL_BACKEND_RTT_LOG_MESSAGE_QUEUE_TIMEOUT=100
CONFIG_SHELL_BACKEND_RTT_LOG_MESSAGE_QUEUE_SIZE=10
CONFIG_SHELL_RTT_INIT_LOG_LEVEL_INF=y
I run JLinkRTTLogger on PC to connect RTT console:
JLinkRTTLogger -Device NRF52840_XXAA -RTTChannel 1 -if SWD -Speed 4000 ~/rtt.log
The result is the device keep rebooting:
