RTT Output fails

[John]

I am using SDK V1.8 and have noticed that RTT output will run for a short time then stop.

Debug is still running because breakpoints can be set, just no printk output or other log data, it is happening regardless of which processor I am using say nRF9160 and nRF52840

RTT has been initiated withing prj.conf using : 

CONFIG_UART_CONSOLE=n
CONFIG_RTT_CONSOLE=y
CONFIG_USE_SEGGER_RTT=y

Any help would be vey much appreciated

Hello,

do you have CONFIG_LOG_IMMEDIATE=y enabled in the prj.conf?

[John]

No it wasn't enabled and when I did enable it, I received the above error.

Sorry, it's CONFIG_LOG_MODE_IMMEDIATE and not CONFIG_LOG_IMMEDIATE I believe.

Just brilliant as always.

Thank you very much Hakon.
