Hi Udi,

No, I did not find any appropriate solution so had to figure out what's going on using scope instead of logging.

Hi,
I'm looking to flush the RTT buffer periodically. Did you manage to use the log_output_flush() function?

If so, could you please share how to use it and how to get the struct pointer that needs to be passed to it?

Hi Runar,

Thanks for your answer, but my question was about how to access its parameter (const struct log_output *output) from the code that is using LOG_DBG macros (that is not defining log_output structure in that code).

For example, how would I finalize this snippet:

#include <zephyr/logging/log.h>

#include <zephyr/logging/log_output.h>

LOG_MODULE_REGISTER(main, LOG_LEVEL_DBG);

int main()

{

LOG_DBG("Hello, World!");

log_output_flush( <what do I specify here?>);

return 0;

}

Thanks again for your help!

From what I can see log_output_flush is already in the SDK(alt least in NCS 2.6) where as the struct log_output is already in the sdk and can be found here.
