RTT doesnt buffer all logs after resetting the target

[Mustafa]

Hello, 

I have an issue with displaying the buffered logs after first connecting with the target. I tried to increase the buffer size of RTT but the terminal line shows always the same amount of logs line ( around 9 lines of logs ), even though I tried to increase the buffer size to 16384 but no luck. 

the project configuration

CONFIG_LOG=y

CONFIG_LOG_MODE_DEFERRED=y

CONFIG_USE_SEGGER_RTT=y

CONFIG_RTT_CONSOLE=y

CONFIG_LOG_MODE_OVERFLOW=y

# CONFIG_LOG_BACKEND_RTT=y

# CONFIG_LOG_BACKEND_RTT_BUFFER=1

# CONFIG_LOG_BACKEND_RTT_BUFFER_SIZE=3000

CONFIG_UART_CONSOLE=n

CONFIG_LOG_BACKEND_UART=n

# Increase log buffer size to prevent logs being dropped.

CONFIG_LOG_BUFFER_SIZE=16384

result output after the first connection

How can I display all the buffered logs after the first connection ?

Platform:

SOC: nrf5340

ncs v2.3.0

Hi,

Try increasing CONFIG_SEGGER_RTT_BUFFER_SIZE_UP
