Logging to file?

[turboscrew]

I need to get quite a lot of logs and quite fast too. How do I do I get the logs into a file?

I tried with Segger RTT logger, but it tends to give up quite quickly. I heard rumors that the RTT logger and debug terminal in the Segger Embedded Studio don't like each other, and that tends to cause problems. How do I get to use only RTT logger and turn debug terminal logging off?

Or are there other means? There are no serial ports left to use.

The J-link RTT Viewer seems to work a bit better, but loses a lot of log messages.

That can be seen if the log file is compared to debug terminal window. The debug terminal doesn't seem to lose log messages.

Hi,

You could try to increase some buffer sizes, giving the viewer a bit more headroom for fetching the log. I got some partial log messages when increasing the message size, but doubled the NRF_LOG_BACKEND_RTT_TEMP_BUFFER_SIZE setting from 64 to 128 and then all messages went through. For the RTT itself you can increase SEGGER_RTT_CONFIG_BUFFER_SIZE_UP (default value 512). Both of those settings will impact memory usage.

I'll try in the next run. The runs are so long, that it probably happens tomorrow.

That worked. Not with the log viewer, but with the logger. The logger stopped acting up and didn't drop any logs.

THANKS!
