Sounds good. Added in case 228881.

I'm not sure what the problem is. Maybe you can share your project so I can try to debug it here? In that case, please make sure that the code can run on a 52DK without any ext. dependencies.

No, I wasn't calling NRF_LOG_PROCESS() anywhere. By this point, I'm not yet in the main loop.

If I try using NRF_LOG_DEFERRED as 1, it makes no difference. If I revert to NRF_LOG_DEFERRED as 0 but make a few calls to NRF_LOG_PROCESS() in various places leading up to the point at which the buffer presumably overflows, I can get a bit further in execution but no matter how liberally I add NRF_LOG_PROCESS() calls, I still get this "Backends flushed" warning ad infinitum.

Hi,

Are you calling NRF_LOG_PROCESS() to empty the log buffer from your main loop? It looks like you're getting buffer overflow. Maybe you can try setting NRF_LOG_DEFERRED to '1' in your app_config.h to see if that helps.
