I've tried everything to get a RTT log message to show up from a dev kit to my computer. The uart log works but no combination of settings will get any RTT message to show up. The docs suggest that setting #define NRF_LOG_BACKEND_SERIAL_USES_RTT 1 should be enough for this to work. It does not output any messages whether its the nrf51 or nrf52. In RTT viewer it says it is connected but if I press a key it says "WARNING: Sent 0 of 1 bytes.". I am using keil to evaluate these chips and this sdk but I cannot get anything to work. Please help me with step by step instructions to get any of the nrf51 or nrf52 sdk examples to output a RTT message using keil.
